The process according to the invention for the production of compounds of formula I is carried out analogously to known processes, e.g. that described in WO 98/12182, and is characterised in that in order to produce those compounds of formula I < R ' 3 >n„ wherein A, Rn, Rι 3 , nι 3 and W have the significances indicated under formula I, for example a compound of formula II wherein Rn, R 13 and nι 3 have the significances indicated, and W 0 is a group (Wo,,) ; R 2 to R 5 , n, and U have the significances indicated under formula I, and R 10 signifies hydrogen or a protecting group, is either a) when R 10 is hydrogen, reacted with a compound of formula III R,S(O) 2 -L (III), wherein R, has the significance indicated under formula I, and L is a leaving group, in an appropriate solvent and in the presence of a base, or b) when R, 0 is a protecting group, this is firstly cleaved and subsequently the resulting compound of formula II, wherein R, o signifies hydrogen, is reacted as described under a) with a compound of formula III. Depending on the properties (reactivity) of the substituents in the groups W 0 ι to Wo, and in the pyridyl moiety of the compounds of formula II, these will suitably be present either as "free" pyrazole derivatives, in which R 10 signifies hydrogen, or as protected pyrazole derivatives, wherein Rι 0 is a protecting group. Appropriate protecting groups are for example benzyl, wherein the phenyl ring may be substituted by halogen, d-d-alkyl, Cι-C 6 -alkoxy, nitro or cyano; allyl, which may be substituted by d-d-alkyl or halogen; tert.-butyl; trityl; benzhydryl (diphenylmethyl); C,-d- alkoxycarbonyl; allyloxycarbonyl; benzyloxycarbonyl, wherein the phenyl ring may be substituted by halogen, d-d-alkyl or d-d-alkoxy; Cι-C -alkylcarbonyi; or benzoyl, wherein the pheny ring may be substituted by halogen, d-C -alkyl or d-d-alkoxy. The technology for introducing and cleaving protecting groups is described for example in "Protective Groups in Organic Synthesis", 2nd Edition, Editors Th. W. Greene and P.G.M. Wuts, John Wiley & Sons, Inc., New York, 1991. Cleavage of the benzyl protecting group, which is optionally substituted on the phenyl ring, in the compounds of formula II (R, 0 = benzyl) may take place by oxidation using the Jones reagent, analogously to the manner described in I.I. Grandberg et al., J. Gen. Chem. USSR (Engl. Transl.) 33, 515 (1963), or using a basic solution of hydrogen peroxide in a water/- methanol mixture, analogously to the manner described in Tetrahedron Lett. 24, 1385 (1983). Cleavage of the benzyl protecting group, which is optionally substituted on the phenyl ring, may also take place under reduction conditions, e.g. using sodium in ammonia, analogously to the manner described in Synthetic Communic. 25, 761 (1995); Chem. Ber. 101 , 3265 (1968); or J. Am. Chem. Soc. 71 , 3994 (1949). Cleavage of the benzyl protecting group, which is optionally substituted on the phenyl ring, may also take place by acidic catalysis, e.g. using trifluoroacetic acid optionally in the presence of an inert organic solvent such as toluene, dichloromethane or 1 ,2-dichloro- ethane, analogously to the manner described in Synthetic Communic. 25, 761 (1995). The tert.-butyl protecting group in the compounds of formula II (R 10 = tert.-butyl) may be cleaved for example with acids, e.g. sulphuric acid solutions, analogously to the manner described in J. Heterocyclic Chem. 30, 389 (1993). The trityl protecting group in the compounds of formula II (R 10 = trityl) may be cleaved for example by acidic catalysis with trifluoroacetic acid optionally in the presence of an inert organic solvent such as cyclohexane, toluene, dichloromethane or chloroform, analogously to the manner described in J. Het. Chem. 14, 1171 (1977). The benzoyl protecting group in the compounds of formula II (R 10 = benzoyl) may be cleaved for example using cobalt hexacarbonyl in an inert solvent such as toluene, xylene or acetonitrile, analogously to the manner described in Bull. Chem. Soc. Jpn. 61 , 4473 (1988). The reaction of the "free", deprotected pyrazole intermediates of formula II, wherein Rio signifies hydrogen, with a compound of formula III, conveniently takes place in an inert solvent such as aliphatic or aromatic hydrocarbons, for example hexanes, petroleum ether, toluene or benzene; halogenated hydrocarbons such as dichloromethane, 1 ,2-dichloro- ethane, chloroform or carbon tetrachloride; ethers such as diethyl ether, tert.-butyl methyl ether; aprotic, polar solvents such as dimethyl sulphoxide (DMSO), dimethyl formamide (DMF), N-methylpyrrolidone (NMP), dimethyl acetamide or sulpholane. Suitable bases are inorganic bases such as carbonates, for example sodium or potassium carbonate, or sodium or potassium bicarbonate; hydroxides such as sodium, potassium or calcium hydroxide; metal oxides such as calcium oxide; hydrides such as sodium hydride; or organic bases such as alkylamines, for example triethylamine, Hϋnig's base (di-isopropyl- ethylamine), dimethyl aniline or diazabicycloundecene (DBU). L in the compound of formula III signifies a leaving group, such as a halide, imidazolyl, triazolyi or R,S(O) 2 -O-. The compounds of formula I, wherein in groups W, to W 3 the substituent R 3 signifies halogen, may be obtained directly from the corresponding compounds of formula I, wherein R 3 is hydrogen, whilst taking into consideration the reactivities of the remaining substituents, by means of halogenation e.g. with elementary chlorine, bromine or iodine, sodium hypochlorite (NaOCI) or iodomonochloride (JCI) in an appropriate solvent and optionally in the presence of a base. Depending on the selected solvents and processes, suitable bases are for example sodium acetate, imidazole or pyridine. Suitable solvents are e.g. glacial acetic acid, water, alcohols, for example ethanol, chlorinated hydrocarbons, for example chlorobenzene, carbon tetrachloride, 1 ,2-dichloro- ethane, chloroform or 1 ,1 ,2,2-tetrachloroethane. Halogenation may also be carried out in the presence of a catalyst, e.g. a Lewis acid such as iron (III) chloride, iron (III) bromide, aluminium chloride or thallium triacetate. The corresponding iodination may also conveniently take place in the presence of an oxidation agent, e.g. nitric acid or sulphur trioxide (SO 3 ). The reaction temperatures are generally in the range -50°C to boiling point of the solvent employed. Such halogenation reactions are described e.g. in "Advanced Organic Chemistry", Editor J. March, John Wiley, New York, 1995, page 476 ff.; Chem. Ber. 43, 2106 (1910); J. Het. Chem. 1965, 410; Bull. Soc. Chim. France 1967, 2617; J. Chem. Soc. 1968, 1507; Synthesis 1982, 844; J. Org. Chem. 1984, 4687; and J. Prakt. Chem. 1989, 799. Alternatively, the compounds of formula I, wherein R 3 signifies bromine or chlorine, may be obtained by reacting the corresponding compounds of formula I, wherein R 3 is hydrogen, with sulphuryl chloride, N-bromosuccinimide (NBS) or N-chlorosuccinimide (NCS). The preferred solvent is e.g. carbon tetrachloride. Reactions of this kind are described for example in WO 98/12182 and DE-A-19 638 234. The choice of appropriate preparation method and of corresponding reaction conditions for the functional conversion in the pyridyl moiety is preferably made at an earlier stage of the reaction, taking into consideration the properties (reactivity) of the substituents already present. This functional conversion conveniently takes place in the presence of an appropriate protecting group in the pyrazole increment, e.g. in compounds of formula II, wherein R 10 is for example benzyl. Then, as indicated above, the protecting group (e.g. R 10 in the compounds of formula II) can be cleaved and the R 1 S(O) 2 - group introduced into the pyrazole increment. Such functionalisations in the pyridyl increment are described e.g. in WO 98/21 199. In the following reaction scheme, the possibilities of functional conversion on the pyridyl increment of the compounds of formulae IV, V, VI and VII are listed by way of example, whereby W 0 in the compounds of formulae IV to IX is a group W 0 ι to W 04 (W04) , wherein R 2 to R 5 , n, and U possess the significances indicated under formula I, and R, 0 signifies a protecting group, such as benzyl, allyl, tert.-butyl, trityl, benzhydryl, alkoxycarbonyl, allyloxycarbonyl, benzyloxycarbonyl, alkylcarbonyl or benzoyl. Reaction scheme: VI VII CO, EtOH, I^CO g , MeJ, PdCI 2 (PPh 3 ) 2 , T NMP VIII IX To produce the compounds of formula I, wherein W signifies a group W 4 (examples P5 to P7), the compounds of formula ll 4 wherein A, R,,, R, 3 , n, 3 and U have the significances indicated under formula I, and R, 0 signifies hydrogen, benzyl or benzyl which is substituted on the phenyl ring by halogen, C,-C -alkyl or C,-C -alkoxy, are important intermediates.

These intermediates of formulae II, to ll 4 are new. The invention thus also relates to these compounds. A number of known standard processes are available for producing the starting compounds of formula II (construction of the pyrazole rings), the choice of appropriate preparation process depending on the properties (reactivity) of the substituents in the respective intermediates. Such processes are described for example in WO 98/21199 and in the references cited therein. Details of a few examples are also given by way of example in preparation examples P1 to P7. The starting compounds 5-chloro-3-fluoro-2-pyrιdιne-carboxylιc acid chloride and 3,5- dιchloro-2-acetylpyrιdιne used in preparation examples P2 and P4 are either known or may be produced in analogous manner to WO 98/21199. Where no specific synthesis is carried out in order to isolate pure isomers, the product may be obtained as a mixture of two or more isomers. The isomers may be separated by methods known perse. In addition, the person skilled in the art is familiar with the order in which certain reactions, e.g. the introduction or cleavage of protecting groups, may be suitably carried out so as to avoid possible secondary reactions. All application methods that are usual in agriculture may be considered for the usage according to the invention of the compounds of formula I or compositions containing them, such as pre-emergence application, post-emergence application and seed dressing, as well as various methods and techniques such as controlled release of active ingredient. To do this, the active ingredient in solution is absorbed onto mineral granulate substrates or polymerised granulates (urea/formaldehyde) and dried. If desired, a coating may be additionally given (coated granules), which enables the active ingredient to be dispensed over a certain period of time The compounds may be used in unmodified form, i e. as they are obtained during synthesis, but are preferably processed in conventional manner with the excipients that are customary in formulation techniques, e.g. into emulsifiable concentrates, directly sprayable or diluable solutions, diluted emulsions, wettable powders, soluble powders, dusts, granules or microcapsuies. Such formulations are described for example in WO 97/34485 on pages 9 to 13. The application process, such as spraying, misting, dusting, wetting, scattering or pouring are selected according to the type of agent, the targeted aims and the prevailing conditions. The formulations, i.e. the agents, preparations or compositions containing the active ingredient of formula I or at least one active ingredient of formula I and normally one or more solid or liquid formulation excipients, are produced in known manner, e.g. by intimately mixing and/or grinding the active ingredients with the formulation excipients such as solvents or solid carriers In addition, surface-active compounds (surfactants) may be used when producing the formulations. Examples of solvents and solid carriers are given for example in WO 97/34485 on page 6. Depending on the type of active ingredient of formula I to be formulated, the surface-active compounds may be non-ionic, 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 for example in WO 97/34485 on pages 7 and 8. Furthermore, the surfactants which are customary in formulation techniques, and are described inter alia in "Mc Cutcheon's Detergents and Emulsifiers Annual" MC Publishing Coφ., Ridgewood New Jersey, 1981 , Stache, H., "Tensid-Taschenbuch", Carl Hanser Verlag, Mϋnchen/Wien, 1981 and M. and J. Ash, "Encyclopedia of Surfactants", Vol Mil, Chemical Publishing Co., New York, 1980-81 , are also suitable for the production of the herbicidal compositions according to the invention. The herbicidal formulations normally contain 0.1 to 99 % by weight, especially 0.1 to 95 % by weight, of herbicide, 1 to 99.9 % by weight, especially 5 to 99.8 % by weight, of a solid or liquid formulation excipient and 0 to 25 % by weight, especially 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 additives, such as stabilisers, e.g. optionally epoxidised vegetable oils (epoxidised coconut oil, rapeseed oil or soya oil), antifoaming agents, e.g. silicone oil, preservatives, viscosity regulators, binding agents, tackifiers, as well as fertilizers or other active ingredients. Normally the active ingredients of formula I may be successfully used either as a mixture comprising the isomers la and lb or as pure isomers la or lb on the plant or the locus thereof at application rates of 0.001 to 4 kg/ha, especially 0.005 to 2 kg/ha. The dosage necessary for the desired effect can be determined by tests. It is dependent on the type of activity, the stage of development of the cultivated plant and of the weed, as well as on the application (locus, time, method) and may vary within a wide range depending on these parameters. The compounds of formula I, and normally in particular the isomers of formula la, are notable for their herbicidal and growth-inhibiting properties, which enable them to be used in crops of useful plants, especially cereals, cotton, soya, sugar beet, sugar cane, plantations, rape, maize and rice, as well as for non-selective weed control (Total Vegetation Management, TVM). Crops are also understood to be those which have been made tolerant towards herbicides or classes of herbicide by means of conventional breeding or by genetic engineering. The weeds to be controlled are both monocot and dicot weeds, for example Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Phaseolus, Echinochloa, Sciφus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.
