[0204] b) transformation in an inert solvent in the presence of an anhydride or antimony pentachloride, and following aqueous treatment, to form a compound of XXXXI 100

[0205] (so-called Katada reaction), and the halogenation of this compound if necessary in the presence of a base and a suitable solvent as described under variant a).

[0206] The above methods of preparation are explained in more detail in the following reaction schemes 1 to 12.

[0207] The preparation of a compound of formula I 101

[0208] wherein R.sub.1 to R.sub.3, A and W are as defined under formula I, is explained in the following reaction scheme 1: 102

[0209] The pyridine derivatives of formula I, wherein R.sub.3 is a HOOC-- or R.sub.5OOC group, may be prepared according to variant a) in reaction scheme 1 in a manner analogous to known methods, a useful method being to react for example the 6-halogen pyridine (L.sub.4=halogen) of formula II in the presence of a palladium or nickel catalyst, such as a palladium triphenylphosphine complex (PdCl.sub.2(PPh.sub.3).sub.2), with carbon monoxide under pressure in an autoclave, if necessary in the presence of an alcohol of formula V

R.sub.5--OH (V)

[0210] and a base, such as a trialkylamine, for example triethylamine.

[0211] According to variant b) in reaction scheme 1, pyridine derivatives of formula I, wherein R.sub.3 is a B.sub.1--C.sub.2-C.sub.8alkenyl, B.sub.1--C.sub.2-C.sub.8alkinyl or B.sub.2--C(R.sub.12).dbd.CH group, are obtainable in a manner analagous to known methods, such as those described in "Transition Metals in Organic Synthesis", Editor S. Gibson, Oxford Press, 1997, for example starting from a 6-halogen pyridine of formula II (L.sub.4=halogen) under the conditions of the Heck reaction with an olefin in the presence of a palladium catalyst, such as palladium(II) acetate (Pd(CH.sub.3COO).sub.2), a tertiary amine, such as triethylamine, and a solvent. According to variant c) in reaction scheme 1, pyridine derivatives of formula I, wherein R.sub.3 is a cyano group, are obtainable for example directly by reacting for example the 6-halogen pyridine of formula II (L4 =halogen) with a cyanidation reagent such as an alkali metal cyanide, for example potassium or sodium cyanide, a transition metal cyanide, for example copper cyanide, a tetraalkylammonium cyanide or trialkylsilyl cyanide, for example trimethylsilyl cyanide, in an inert solvent.

[0212] According to variant d) in reaction scheme 1, a reactivation for example of the 6-halogen pyridine of formula II (L.sub.4=halogen) first takes place via oxidation to form the corresponding pyridine-N-oxide of formula IV and the reaction thereof with dimethylcarbamoyl chloride to form the reactive 1-carbamoyloxypyridinium salt. The following reaction of this pyridinium salt with a cyanidation reagen is carried out in a manner analogous to that described under c). Such cyanidation reactions are described for example in Heterocycles 22, 1121 (1984), J.Org.Chem. 48, 1375 (1983) and U.S. Pat. No. 4,776,219.

[0213] Further derivatization of the pyridine derivatives of formula I, primarily obtainable according to variants a) to d) in reaction scheme 1, wherein R.sub.3 is a carboxyl, alkoxycarbonyl, alkenyl or alkinyl, or cyano group, and A is nitrogen, can be readily accomplished, taking into account the chemical reactivities of the pyridyl and W parts (groups W.sub.1 to W.sub.10), in a manner analogous to known standard methods, such as esterification, transesterification, hydrolysis, oxidative or reductive processes, or condensation reactions, for example the Wittig-Horner reaction. Such standard methods are described for example in WO 93/06090, EP-A-0 240 659 and in Houben-Weyl, "Methoden der Organischen Chemie", Vol. E1, Thieme Verlag Stuttgart, 1982.

[0216] For the preparation of the compounds of formula Ia according to the invention, many known standard methods are available, such as those described for example in EP-A-0 438 209 and DE-OS-19 604 229 (R.sub.16=Cyano). In reaction scheme 2, a selection of suitable preparative processes is shown, wherein the choice of reaction pathways and reagents depends on the reactivities of the substituents in the intermediate stages. Starting for example from a compound of formula III, the aminopyridine of formula VI can be obtained by reacting with ammonia in an inert solvent, if necessary in an autoclave at temperatures from -10 to 180.degree. C. This aminopyridine can be reacted in the presence of a base and a solvent either

[0217] a) with a chloroformate of formula VII (X.sub.6=O or S) to form a pyridyl carbamate of formula VII, or

[0218] b) with oxalyl chloride, phosgene (X.sub.6=O) or thiophosgene (X.sub.6=S) to form an iso(thio)cyanate of formula IX. Such reactions are described for example in Angew. 1971, 407. The carbamate and iso(thio)cyanate of formulae VII and IX can be cyclized in the presence of the enamine derivative of formula X in an inert solvent to form the uracil derivative of formula XI, the reaction of the iso(thio)cyanate of formula IX being advantageously carried out in the presence of 0.1-1.5 equivalents of a base, for example sodium hydride, potassium tert-butylate or alkaline earth metal oxide or hydroxide, for example barium hydroxide. The desired compounds of formula Ia can be prepared from the uracils of formula XI, according to standard methods, in the presence of an inert solvent and at least 1 equivalent of a base, for example an alkali metal carbonate such as potassium carbonate,

[0219] c) with an alkylation agent of formula XII to form an N-alkyl derivative of formula Ia (R.sub.15=alkyl), or

[0220] d) in analogy to WO 97/05116 with a hydroxylamine derivative of formula XII, wherein L.sub.1 is a leaving group such as HOS(O).sub.2O-- 105

[0221] for example 2,4-dinitrophenylhydroxylamine or hydroxylamine-O-sulfonic acid, to form the N-amino derivative of formula Ia (R.sub.15=amino). The desired thiono derivatives of formula Ia (X.sub.6, X.sub.7=S ) can be obtained by thionization, for example with phosphorus pentasulfide or Lawesson's reagent.

[0225] The compounds of formula Ib can be prepared according to known methods, for example according to reaction scheme 3 (variant a)) by reacting a 2-halogen pyridine derivative of formula IlIl (L4=halogen) with hydrazine, preferably in an amphiprotic solvent, such as alcohols, by analogy with GB-A-2 230 261, to form the 2-hydrazino derivative of formula XIV.

[0226] This is reacted with a diketone of formula XV, by analogy with DE OS-1 9754348, or with a dihalogen ketone of formula XVa, by analogy with WO 97/07104, to form the hydrazone derivative of formula XVII. Subsequent cyclization to the desired compound of formula Ib takes place in the presence of the phosphoran derivative of formula XVIII, if necessary in the presence of a base, for example 4-dimethylaminopyridine. If X.sub.8=O in a compound of formula Ib, then thionization can subsequently be carried out in a manner similar to that described under reaction scheme 2 (X.sub.8=S). According to reaction scheme 3, the hydrazone derivative of formula XVII can also be obtained from the 2-aminopyridine derivative of formula VI by means of diazotization, preferably under exclusion of water, and subsequent coupling with the keto acid of formula XVI (Japp-Klingemann reaction similar to that described under DE-OS-19754348)--(variant b) in reaction scheme 3).

For those cases (variant c)) where, in a compound of formula Ig, R.sub.33 is hydrogen and X.sub.13 and/or X.sub.14 are/is oxygen, alkylation can subsequently be carried out, if necessary with an alkylation reagent of formula XXI, on the free N-atom of the hydantoin ring and the ring carbonyl group then thionized (X.sub.13 and/or X.sub.14=S).

[0232] The preparation of a compound of formula Ih 110

[0247] According to reaction scheme 8, the pyrrolindione derivatives of formula Ie and the tetrahydroisoindolindione derivatives of formula If can be obtained in a manner analogous to known methods, for example by reacting an anhydride of formula XXVIII (variant a)) and/or XXVIIla (variant b)) with an aminopyridine of formula VI in an inert solvent, such as ether, for example dioxan, or a lower alkylcarboxylic acid, for example propionic acid, at temperatures of 20-200.degree. C. The compounds of formulae Ie and If (X.sub.9 to X.sub.12=O) which are obtainable according to reaction scheme 8 can be thionized if necessary with a suitable sulfur reagent (X.sub.9 to X.sub.12=S).

[0248] The preparation of a compound of formula Ii 118

A suitable (thio)carbonylation reagent of formula XXXI is for example phosgene, diphosgene, thiophosgene or carbonyidiimidazol. L.sub.3 in a compound of formula XXXI is therefore a leaving group such as a halogen, for example, chlorine or bromine, trichloromethoxy or 120

According to variant b), the hydrazinopyridine derivative of formula XIV can be cyclized with an iminoether of formula XXXVI to form a triazolone derivative of formula Ik, wherein X.sub.19 is oxygen, and R.sub.38 is hydrogen, and then if necessary alkylated or thionized as described under variant a). According to variant c) in reaction scheme 10, the hydrazinopyridine derivative of formula XIV can be reacted first with an aldehyde of formula XXXVII and then, in the presence of a lower alkylcarboxylic acid, such as acetic acid, with an alkali metal cyanate to form a compound of formula XXXVIII which, if necessary, is not isolated, and finally cyclized with an oxidizing agent, such as alkali metal hypochlorite (Javelle) to form a compound of formula Ik, wherein X.sub.19 is oxygen, and R.sub.38 is hydrogen. If necessary, the resulting compound of formula Ik can be alkylated or thionized, as described under variant a).

[0254] In certain cases, compounds of formula I can also be usefully obtained in a manner analogous to that described in J. Het. Chem. 15, 1221 (1978) by the substitution of a 2-halogen pyridine of formula IlI (L.sub.4=halogen), if necessary in the presence of a suitable solvent and a base, with the desired heterocycles of formulae W.sub.01 to W.sub.010 123

[0258] The preparation of compounds of formula 11 is explained in reaction scheme 12. 126

[0259] The pyridin-N-oxides of formula XXXX (reaction scheme 12) can be prepared according to known methods, such as described in Org. Synth. 4, 828 (1963); ibid. 3, 619 (1955); U.S. Pat. No. 3,047,579; and B. Iddon and H. Suschitzky in "Polychloroaromatic Compounds", Editor H. Suschitzky, Plenum Press, London 1974, page 197, a useful method being to react the pyridine derivatives of formula XXXIX with oxidizing agents, such as organic peroxy acids, for example m-chloroperbenzoic acid, peracetic acid and pertrifluoracetic acid, or aqueous hydrogen peroxide solution or hydrogen peroxide urea adduct together with carboxylic acids and/or carboxylic acid anhydrides, or inorganic peroxy acids, for example peroxymonosulfuric acid (Caro's acid). Suitable solvents are, for example, water, organic acids such as acetic acid and trifluoracetic acid, halogenated hydrocarbons such as dichloromethane and 1,2-dichloroethane, esters such as ethyl acetate, ethers such as tetrahydrofuran and dioxan or mixtures comprising these solvents. The reaction temperatures lie within the range of -20.degree. C. to 100.degree. C., depending on the solvent or solvent mixture used. The pyridin-N-oxides of formula XXXX can be halogenated either directly according to known methods, for example with phosphorus oxychloride, phosphorus oxybromide, sulfuryl chloride, thionyl chloride or phosphorus pentachloride in phosphorus oxychloride to form the halogen pyridine derivatives of formula II (L.sub.4=halogen), or first reacted--likewise according to known methods (e.g. Quart. Rev. 10, 395 (1956); J. Am. Chem. Soc. 85, 958 (1963); and J. Org. Chem. 26, 428 (1961))--in the presence of anhydrides, for example acetic anhydride, trifluoracetic anhydride and methanesulfonic acid anhydride in a suitable inert solvent, such as halogenated hydrocarbons, for example dichloromethane and 1,2-dichloroethane, amides such as N,N-dimethylformamide and 1 -methyl-2-pyrrolidone and if necessary in the presence of sodium acetate, to form the pyridol derivatives of formula XXXXI, which can then then be halogenated to form halogen pyridines of formula II, as described above for compounds of formula XXXX (L.sub.4=halogen).

[0260] The reaction temperatures for this transformation reaction generally lie within the range of -30.degree. C. to 80.degree. C. By analogy with Tetrahedron 37, 187 (1981), antimony pentachloride (Katada reaction) presents itself as a further variant for the above transformation reaction.

[0261] The method described in the invention for the preparation of compounds of formula II 127

The starting compounds of formula XXXIX used in reaction scheme 12 can be prepared in a manner analogous to the methods described for compounds of formula Ia to Ik (R.sub.3=hydrogen) under reaction schemes 2 to 11.

[0263] The compounds of formulae III and VI are known or can be prepared according to known methods, as described in DE-A-3 917 469; WO 97/07114; WO 92/00976; JP-A-58-213 776; EP-A-0 012 117; EP-A-0 306 547; EP-A-0 030 215; EP-A-0 272 824; EP-A-0 500 209; U.S. Pat. Nos. 4,996,323; 5,017,705; WO 97/05112; J. Het. Chem. 11, 889 (1974); J. Het. Chem 21, 97 (1984); Tetrahedron 41, 4057 (1985); Heterocycles 22, 117; Synth. 1988, 938; J. Med. Chem. 25, 96. The 2-aminopyridines of formula VI can in addition be prepared by Curtius, Hofmann or Lossen reactions from corresponding pyridine derivatives with carboxylic acid, carboxylic acid chloride, carboxylic acid azide, carboxylic acid ester or carboxylic acid amide functions in Position 2.

[0264] The reagents of formulae V, VII, X, XII, XIII, XV, XVa, XVI, XVIII, XIX, XXI, XXII, XXIVa, XXIVb, XXV, XXVa, XXVb, XXVc, XXXIV, XXVIII, XXVIIIa, XXIX, XXXI, XXXII, XXXIV, XXXV, XXXVI and XXXVII as used in reaction schemes 1 to 10 are either known or can be prepared in a manner analogous to disclosed methods.

[0265] The heterocycles of formulae W.sub.01 to W.sub.010 are either known or can be prepared in a manner analogous to known standard methods of heterocyclic chemistry.

[0266] The reactions for obtaining the compounds of formula I are advantageously carried out in aprotic inert organic solvents. Such solvents are hydrocarbons such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons such as dichloromethane, trichloromethane, tetrachloromethane or chlorobenzene, ethers, including diethyl ether, 1,2-dimethoxyethane, diglyme, tetrahydrofuran or dioxane, nitriles such as acetonitrile or propionitrile, amides such as N,N-dimethyl formamide, diethyl formamide or N-methyl-pyrrolidinone. The reaction temperatures are preferably in the range from -20.degree. to +120.degree. C. The reactions are usually slightly exothermic and can as a rule be carried out at room temperature. The reaction mixture can be heated for a brief time to boiling point to shorten the reaction time or also to initiate the reaction. The reaction times can also be shortened by addition of a few drops of a base as reaction catalyst. Particularly suitable bases are tertiary amines such as trimethylamine, triethylamine, quinuclidine, 1,4-diazabicyclo[2.2.2]octane, 1,5-diazabicyclo[4.3.0]non-5- -ene or 1,5-diazabicyclo[5.4.0]undec-7-ene. Further suitable bases are also inorganic bases, typically hydrides such as sodium or calcium hydride, hydroxides such as sodium and potassium hydroxide, carbonates such as sodium and potassium carbonate, or hydrogencarbonates such as potassium and sodium hydrogencarbonate. The compounds of formula I can be isolated in conventional manner by concentrating the reaction mixture and/or removing the solvent by evaporation and by recrystallizing or triturating the solid residue in a solvent in which it is not readily soluble, typically an ether, an aromatic hydrocarbon or a chlorinated hydrocarbon, or by means of column chromatography and a suitable eluent.

[0267] The compounds of formula I or compositions containing them may be used according to this invention by all standard methods of application used in agriculture, including preemergence application, postemergence application and seed dressing, as well as by different methods and techniques such as controlled release. For controlled release, a solution of the herbicide is applied to mineral granular carriers or to polymerized granules (urea/formaldehyde) and then dried. A coating can then be additionally applied (coated granules) that allows the herbicide to be released at a controlled rate over a specific period of time. The compounds of formula I may be used as herbicides in unmodified form, i.e. as obtained in the synthesis. Preferably they are processed in conventional manner with the auxiliary agents customarily employed in formulation technology, e.g. to emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates or microcapsules. Such formulations are described, for example, in WO 97/34485 on pages 9 to 13. As with the type of agents, the methods of application such as spraying, atomizing, dusting, wetting, scattering or pouring, are selected in accordance with the intended objectives and the prevailing circumstances. The formulations, i.e. the agents, preparations, or compositions containing the compound of formula I or at least one compound of formula I and usually one or more than one liquid or solid formulation assistant, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the herbicide with said formulation auxiliaries, typically solvents or solid carriers. Surface-active compounds (surfactants) may additionally be used for preparing the formulations. Examples of solvents and solid carriers are described in WO 97/34485 on page 6. Depending on the herbicide of formula I to be formulated, suitable surface-active compounds are nonionic, cationic and/or anionic surfactants and surfactant mixtures having good emulsifying, dispersing and wetting properties. Examples of suitable anionic, non-ionic, and cationic surfactants are listed in WO 97/34485 on pages 7 and 8. Also the surfactants customarily employed in the art of formulation and described, inter alia, in "McCutcheon's Detergents and Emulsifiers Annual" MC Publishing Corp., Ridgewood N.J., 1981, Stache, H., "Tensid-Taschenbuch" (Handbook of Surfactants), Carl Hanser Verlag, Munich/Vienna, 1981, and M. and J. Ash, "Encyclopedia of Surfactants", Vol I-III, Chemical Publishing Co., New York, 1980-81 are suitable for manufacture of the herbicides according to the invention.

[0268] The herbicidal compositions will as a rule contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of herbicide, from 1 to 99.9% by weight, preferably from 5 to 99.8% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant. Whereas it is preferred to formulate commercial products as concentrates, the end user will normally use dilute formulations. The compositions may also contain further ingredients, such as: stabilisers, e.g. where appropriate epoxidized vegetable oils (epoxidized coconut oil, rapeseed oil, or soybean oil); antifoams, typically silicone oil; preservatives; viscosity regulators; binders; and tackifiers; as well as fertilizers or other chemical agents. The compounds of formula I are usually applied with success to the plants or the locus thereof in concentrations of 0.001 to 4 kg/ha, especially 0.005 to 2 kg/ha. The concentration required to achieve the desired action can be determined by experimentation. It will depend on the type of action, the development stage of the cultivated plant and of the weed, as well as on the application (locus, time, method), and as a result of these variables can vary over a wide range. The compounds of formula I have excellent herbicidal and growth inhibiting properties, which make them suitable for application in crops of cultivated plants, especially in cereals, cotton, soybeans, sugar beet, sugar cane, plantations, rape, maize, and rice, and for the non-selective control of weeds. Crops will also be understood as meaning those crops that have been made tolerant to herbicides or classes of herbicides by conventional breeding or genetic engineering methods. The weeds to be controlled may be monocot as well as dicot weeds, typically Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola, and Veronica.

BIOLOGICAL EXAMPLES

Example B1

Preemergence Herbicidal Action

[0842] Monocot and dicot test plants are sown in standard soil in plastic pots. Immediately after sowing, the plants are sprayed at a concentration of 2 kg active ingredient/ha with an aqueous suspension of the test compound prepared from a 25% wettable powder (Example F3, b)) according to WO 97/34485) or an emulsion of the test compound prepared from a 25% emulsifiable concentrate (Example F1 c)) according to WO 97/34485) (500 l of water/ha). The test plants are then cultivated in the greenhouse under optimum conditions. The test is evaluated 3 weeks later on a rating scale of 1-9 (1=total damage, 9=no action). Ratings of 1 to 4 (especially of 1 to 3) denote good to very good herbicidal action.
