Certain hydrazone derivatives are proposed in the literature as insecticidally active ingredients in pesticides. However, the biological properties of these known compounds are not entirely satisfactory in the field of pest control, which is why there is a need to provide other compounds having pesticidal properties, in particular for controlling insects, this object being achieved according to the invention by provision of the present compounds I. The compounds I can exist as E/Z isomers, for example in the following two isomeric forms Accordingly, the compounds I are, if appropriate, also to be understood as meaning hereinbelow appropriate E/Z isomers, even if the latter are not specifically mentioned in each case. Some of the compounds I may exist as tautomers, for example, if R 6 is H then corresponding compounds I, i.e. those in which X is a substructure -N(H)-C(R 7 )=Y, may be in equilibrium with the respective tautomers comprising a substructure -N=C(R 7 )-YH. Accordingly, the compounds I hereinbelow are, if appropriate, also to be understood as meaning corresponding tautomers, even if the latter are not mentioned specifically in each case. The compounds I and, if appropriate, their E/Z isomers and tautomers can exist as salts. Compounds I which have at least one basic centre can form, for example, acid addition salts. These acid addition salts are formed, for example, with strong inorganic acids, such as mineral acids, for example sulfuric acid, a phosphorus acid or a hydrohalic acid, with strong organic carboxylic acids, such as unsubstituted or substituted, for example halogen-substituted, C 1 -C 4 alkanecarboxylic acids, for example acetic acid, such as saturated or unsaturated dicarboxylic acids, for example oxalic acid, malonic acid, maleic acid, fumaric acid or phthalic acid, such as hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or such as benzoic acid, or with organic sulfonic acids such as unsubstituted or substituted, for example halogen-substituted, C 1 -C 4 alkane- or arylsulfonic acids, for example methane- or p-toluenesulfonic acid. Furthermore, compounds I having at least one acidic group can form salts with bases. Examples of suitable salts with bases are metal salts, such as alkali metal salts or alkaline earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower-alkylamine, for example ethyl-, diethyl-, triethyl- or dimethylpropylamine, or a mono-, di- or trihydroxy-lower-alkylamine, for example mono-, di- or triethanolamine. Furthermore, appropriate internal salts may be formed, if appropriate. Preferred within the scope of the invention are agrochemically advantageous salts; however, salts which are disadvantageous for agrochemical purposes, for example salts which are toxic to bees or fish, and which are employed, for example, for the isolation or purification of free compounds I or their agrochemically utilizable salts, are also embraced by the invention. Due to the close relationship between the compounds I in free form and in the form of their salts, the free compounds I or their salts hereinabove and hereinbelow are, analogously, also to be understood as meaning the corresponding salts or the free compounds I, if appropriate. This also applies correspondingly to E/Z isomers and tautomers of compounds I and their salts. Unless otherwise defined, the general terms used hereinabove and hereinbelow have the meanings given below. Halogen - as a group per se and as structural element of other groups and compounds, such as haloalkyl, haloalkoxy, haloalkoxyalkyl and haloalkenyl - is fluorine, chlorine, bromine or iodine, in particular fluorine, chlorine or bromine. Unless otherwise defined, carbon-containing groups and compounds have in each case at least 1 but not more than 8, preferably at least 1 but not more than 4, in particular 1 or 2, carbon atoms. C 3 -C 6 Cycloalkyl is cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Alkyl - as a group per se and as structural element of other groups and compounds, such as haloalkyl, alkoxy, alkoxyalkyl, alkylthio, alkylsulfynyl or alkylsulfonyl - is, in each case with due consideration of the number of carbon atoms existing in each case in the particular group or compound, either straight-chain, i.e. methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl or octyl, or branched, for example isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl, neopentyl or isooctyl. Halogen-substituted carbon-containing groups and compounds, such as haloalkyl, haloalkoxy or haloalkenyl, can be partially halogenated or perhalogenated, it being possible for the halogen substituents to be identical or different in the case of polyhalogenations. Examples of haloalkyl - as a group per se and as structural element of other groups and compounds, such as halocycloalkylalkyl and haloalkenyl - are methyl which is mono- to trisubstituted by fluorine, chlorine and/or bromine, such as CHF 2 or CF 3 ; ethyl which is mono- to pentasubstituted by fluorine, chlorine and/or bromine, such as CH 2 CF 3 , CF 2 CF 3 , CF 2 CC1 3 , CF 2 CHC1 2 , CF 2 CHF 2 , CF 2 CFC1 2 , CF 2 CHBr 2 , CF 2 CHC1F, CF 2 CHBrF or CC1FCHC1F; propyl or isopropyl, mono- to heptasubstituted by fluorine, chlorine and/or bromine, such as CH 2 CHBrCH 2 Br, CF 2 CHFCF 3 , CH 2 CF 2 CF 3 or CH(CF 3 ) 2 ; and butyl or one of the isomers thereof, mono- to nonasubstituted by fluorine, chlorine and or bromine, such as CF(CF 3 )CHFCF 3 or CH 2 (CF 2 ) 2 CF 3 . Acyl groups can be formyl, acetyl, propionyl, butyryl, isobutyryl, valeryl, isovaleryl, pivaloyl, hexanoyl, heptanoyl, octanoyl, aroyl, for example benzoyl, or heteroaroyl, for example thienoyl. Examples of heteroaryl radicals are thienyl, pyrryl, imidazolyl, pyrazolyl, triazolyl, thiazolyl, isothiazolyl, pyridyl, indolyl, benzo[b]thienyl or benzo[b]furyl.

Salts of compounds I can be converted in a manner known per se to give other salts of compounds I, for example acid addition salts can be converted to other acid addition salts, for example by treating a salt of an inorganic acid, such as a hydrochloride, with a suitable metal salt, such as a sodium, barium or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt which forms, for example silver chloride, is insoluble and thus separates out from the reaction mixture. Depending on the procedure and on the reaction conditions, the compounds I which have salt-forming properties can be obtained in free form or in the form of salts. The compounds I and II can exist in the form of one of the isomers which are possible or in the form of a mixture of these, for example depending on the number and the absolute and relative configuration of the asymmetric carbon atoms as pure isomers, such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures; the invention relates to the pure isomers as well as to all isomer mixtures which are possible and is to be understood accordingly hereinabove and hereinbelow even when stereochemical details are not mentioned specifically in each case. Diastereomer mixtures and racemate mixtures of compounds I and II which can be obtained according to the process - depending on the selection of starting materials and procedures - or via other routes can be separated in a known manner by virtue of the physico-chemical differences of the components to give the pure diastereomers or racemates, for example by fractional crystallization, distillation and/or chromatography. Enantiomer mixtures which can thus be obtained, such as racemates, can be resolved by known methods to give the optical antipodes, for example by recrystallization from an optically active solvent, by chromatography on chiral adsorbents, for example high-pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable microorganisms, by cleavage with specific, immobilized enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, only one enantiomer being complexed in the process. Pure diastereomers or enantiomers can be obtained according to the invention not only by separating suitable isomer mixtures, but also by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process according to the invention using starting materials with correspondingly suitable stereochemistry. If individual components differ with regard to their biological activity, it is advantageous to isolate, or synthesize, in each case the biologically more active isomer, for example enantiomer, or isomer mixture, for example enantiomer mixture. The compounds I and II can also be obtained in the form of their hydrates and/or include other solvents, for example those which may need to be used for crystallizing compounds which are in solid form. The invention relates to all those embodiments of the process by which, starting with a compound which can be obtained during any stage of the process as starting material or intermediate, all or some of the missing steps are carried out or a starting material is used in the form of a derivative or salt and/or a racemate or antipode thereof or, in particular, is formed under the reaction conditions. In the process of the present invention, starting substances and intermediates which are preferably used are those which lead to the compounds I which have been described at the outset as being particularly valuable. In particular, the invention relates to the preparation processes described in Examples HI to H10. The invention also provides starting materials and intermediates, in each case in free form or in salt form, which are novel and are used according to the invention for the preparation of the compounds I or the salts thereof, their use as well as processes for their preparation.

The active ingredients according to the invention are particularly suitable for controlling, i.e. containing or destroying, pests of the abovementioned type which are found in particular on plants, mainly on useful plants and ornamentals in agriculture, horticulture and forestry, or on parts of such plants, such as fruits, flowers, foliage, stalks, tubers or roots, and, in some cases, the protective effect is also extended to newly-forming parts of the plants. Target crops which are suitable are, in particular, cereals such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar beet or fodder beet; fruit, for example pomaceous fruit, stone fruit and soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; pulses, such as beans, lentils, peas or soya beans; oil crops such as oilseed rape, mustard, poppy, olives, sunflowers, coconut, castor oil, cocoa or groundnuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruits such as oranges, lemons, grapefruit or tangerines; vegetables such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or bell peppers; the laurel family, such as avocado, cinnamon or camphor; and also tobacco, nuts, coffee, egg plants, sugar cane, tea, pepper, grapevines, hops, the plantain family, natural latex plants and ornamentals. The active ingredients according to the invention are particularly suitable for controlling Boophilus microplus, Nilaparvata lugens, Panonychus ulmi and Tetranychus urticae in vegetable, fruit and rice plants. Other fields of application for the active ingredients according to the invention are the protection of stored products and stores and materials, and, in the hygiene field, in particular the protection of domestic animals and productive livestock against pests of the abovementioned type. The invention therefore also relates to pesticides such as emulsifiable concentrates, suspension concentrates, ready-to-spray or ready-to-dilute solutions, spreadable pastes, dilute emulsions, wettable powders, soluble powders, dispersible powders, wettable powders, dusts, granules or encapsulations in polymeric substances, all of which comprise - at least - one of the active ingredients according to the invention and are to be selected according to the intended aims and prevailing circumstances. In these compositions, the active ingredient is employed in pure form, a solid active ingredient for example in a specific particle size, or, preferably, together with - at least - one of the auxiliaries conventionally used in the art of formulation, such as extenders, for example solvents or solid carriers, or such as surface-active compounds (surfactants). Solvents which are suitable are, for example: unhydrogenated or partially hydrogenated aromatic hydrocarbons, preferably the fractions C 8 to C 12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffins or cyclohexane, alcohols, such as ethanol, propanol or butanol, glycols as well as their ethers and esters, such as propylene glycol, dipropylene glycol ether, ethylene glycol or ethylene glycol monomethyl or monoethyl ether, ketones such as cyclohexanone, isophorone or diacetanol alcohol, strongly polar solvents such as N-methylpyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, unepoxidized or epoxidized vegetable oils, such as unepoxidized or epoxidized rapeseed oil, castor oil, coconut oil or soya oil, and silicone oils. Solid carriers which are used, for example for dusts and dispersible powders, are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silicas or highly-disperse absorptive polymers. Suitable paniculate, adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carriers are calcite or sand. Moreover, a large number of granulated materials of inorganic or organic nature can be used, especially dolomite or comminuted plant residues. Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient to be formulated. The surfactants listed below are only to be considered as examples; the specialist literature describes a large number of other surfactants which are conventionally used in the art of formulation and suitable according to the invention. Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can comprise 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols. Other suitable non-ionic surfactants are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylene diaminopolypropylene glycol and alkyl polypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and comprise 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The abovementioned compounds customarily comprise 1 to 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other substances which are suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate. The cationic surfactants are mainly quaternary ammonium salts which comprise, as substituents, at least one alkyl radical having 8 to 22 carbon atoms and as further substituents lower, halogenated or unhalogenated alkyl, benzyl or lower hydroxyalkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimethylammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide. Suitable anionic surfactants can be either water-soluble soaps or water-soluble, synthetic surface-active compounds. Soaps which are suitable are the alkali metal salts, alkaline earth metal salts and substituted or unsubstituted ammonium salts of higher fatty acids 1 Q-C 2 ), such as the sodium salts or potassium salts of oleic or stearic acid, or of natural mixtures of fatty acids which can be obtained from, for example, coconut oil or tall oil; other surfactants which may be mentioned are the fatty acid methyltaurides. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or fatty sulfates are, as a rule, in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and have, as a rule, an alkyl radical having 8 to 22 carbon atoms, alkyl also including the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or calcium salts of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives comprise preferably 2 sulfonic acid groups and a fatty acid radical having approximately 8 to 22 carbon atoms. Alkylarylsulfonates are, for example, the sodium salts, calcium salts or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Suitable phosphates, for example salts of the phosphoric ester of a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids, are also suitable. As a rule, the compositions comprise 0.1 to 99%, in particular 0.1 to 95%, of active ingredient and 1 to 99.9%, in particular 5 to 99.9%, of - at least - one solid or liquid auxiliary, it being possible, as a rule, for 0 to 25%, in particular 0.1 to 20%, of the compositions to be surfactants (% in each case meaning per cent by weight). While concentrated compositions are more preferred as commercial products, the end user employs, as a rule, dilute preparations with considerably lower concentrations of active ingredients. Preferred compositions are, in particular, composed as follows (% = per cent by weight): Emulsifiable concentrates: Active ingredient: 1 to 90%, preferably 5 to 20% Surfactant: 1 to 30%, preferably 10 to 20 % Solvent: 5 to 98%, preferably 70 to 85% Dusts: Active ingredient: 0.1 to 10%, preferably 0.1 to 1% Solid carrier: 99.9 to 90%, preferably 99.9 to 99% Suspension concentrates: Active ingredient: 5 to 75%, preferably 10 to 50% Water: 94 to 24%, preferably 88 to 30% Surfactant: 1 to 40%, preferably 2 to 30% Wettable powders: Active ingredient: 0.5 to 90%, preferably 1 to 80% Surfactant: 0.5 to 20%, preferably 1 to 15% Solid carrier: 5 to 99%, preferably 15 to 98% Granules: Active ingredient: 0.5 to 30%, preferably 3 to 15% Solid carrier: 99.5 to 70%, preferably 97 to 85% By adding other insecticidal active ingredients, the action of the compositions according to the invention can be broadened considerably and adapted to prevailing circumstances. Suitable active ingredients which are added are, for example, representatives of the following classes of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, acylureas, carbamates, pyrethroids, nitroenamines and derivatives, pyrroles, thioureas and derivatives, chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions according to the invention can also comprise other solid or liquid auxiliaries, such as stabilizers, for example unepoxidized or epoxidized vegetable oils (for example epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, as well as fertilizers and other active ingredients for achieving specific effects, for example acaricides, bactericides, fungicides, nematicides, molluscicides or selective herbicides. The compositions according to the invention are prepared in a known manner, for example in the absence of auxiliaries by grinding, screening and/or compressing a solid active ingredient or mixture of active ingredients, for example to obtain a particular particle size, and in the presence of at least one auxiliary, for example by intimately mixing and/or grinding the active ingredient or mixture of active ingredients with the auxiliary(ies). The invention also provides these processes for the preparation of the compositions according to the invention and the use of the compounds I for the preparation of these compositions. Other subjects of the invention are the methods of application for the compositions, that is to say the methods for controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, seed-dressing, scattering or pouring, to be chosen according to the intended aims and the prevailing circumstances, and the use of the compositions for controlling pests of the abovementioned type. Typical use concentrations are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. As a rule, the rates of application per hectare are 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g ha, preferably 20 to 600 g/ha. A preferred method of application in the field of crop protection is application to the foliage of the plants (foliar application), it being possible to match frequency and rates of application to the danger of infestation with the pest in question. Alternatively, the active ingredient may reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by introducing the active ingredient in solid form into the locus of the plants, for example in the soil, for example in granular form (soil application). In the case of paddy rice, such granules may be metered into the flooded paddy field. The compositions according to the invention are also suitable for the protection of plant propagation material, for example seed, such as fruits, tubers or kernels, or nursery plants, against animal pests. The propagation material can be treated with the composition before planting, for example seed before sowing. Alternatively, the active ingredients according to the invention can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by coating them with a solid composition. Alternatively, the composition can be applied to the planting site when the propagation material is planted, for example into the seed furrow during sowing. The invention also provides these treatment methods for plant propagation material and the plant propagation material which has been treated in this manner. The examples which follow are intended to illustrate the invention. They do not restrict the invention. Temperatures are given in degrees celcius. Preparation examples General notes The compounds are obtained as mixtures of isomers, in most cases in the form of viscous oils. They can be purified by column chromatography. NMR spectra and elementary analyses confirm the claimed structures. Example HI: 4-Chloro-4' -trifluoromethoxybenzophenone 10.8 g of 4-trifluoromethoxybenzonitrile are added dropwise to a solution of 4-chlorophenylmagnesium bromide in ether (from 22.9 g of l-bromo-4-chlorobenzene and 2.88 g of magnesium filings in 80 ml of ether) and the mixture is subsequently refluxed for 24 hours. After cooling, 50 ml of 50% sulfuric acid are added at 20-30°C; after the exothermal reaction has subsided, stirring of the batch is continued for 1 hour at room temperature. The phases are separated, and the aqueous phase is extracted repeatedly by shaking with ether. The combined organic phases are worked up using saturated NaHCO 3 solution and saturated NaCl solution. The solid crude product is purified by means of flash chromatography (ethyl acetate/hexane 1:20). This gives 14.3 g of the title compound in crystalline form with an m.p. of 74-75°C. Example H2: 4- Chloro-4' -trifluoromethoxybenzophenone hydrazone 10.0 g of 4-chloro-4'-trifluoromethoxybenzophenone, 9.70 g of hydrazine hydrate and 2 ml of acetic acid are refluxed gently for 10 hours in 270 ml of absolute alcohol. The solution is then evaporated, the residue is taken up in dichloromethane, and the mixture is washed with water. Evaporation of the dry organic phase gives 9.34 g of the title compound as white, greasy crystals. Example H3: 4-Chloro-4'-trifluoromethoxybenzophenone N-acetylhydrazone (Compound 1.1 in Table 1) 2.24 g of 4-chloro-4'-trifluoromethoxybenzophenone hydrazone, 0.52 ml of acetyl chloride and 1.04 ml of triethylamine are stirred overnight at room temperature in 40 ml of toluene.

After the mixture has been evaporated, the residue is taken up in dichloromethane and the mixture is washed with water. After drying over MgSO and evaporation, 1.48 g of the title compound remain as a yellow oil. Example H5: 4-Chloro-4 , -rrifluoromethoxybenzophenone N-formyl-N-methylhydrazone (Compound 1.6 in Table 1) 15 g of sodium formate are introduced into 12.5 ml of ether with stirring and with the exclusion of moisture, and 14.7 g of acetyl chloride are added dropwise at 0°C. Stirring is continued for several hours at room temperature, and sodium chloride is filtered off and the mixture is washed with dry ether. This gives a solution of approximately 14.22 g of formyl acetate in ether. Some of this solution, containing approximately 0.38 g of formyl acetate, is added dropwise to a solution of 1.48 g of 4-chloro-4'-trifluoromethoxybenzoρhenone N-methylhydrazone in 20 ml of ether. After a few hours, the reaction has ended, and the mixture is treated with ice-water, and the organic phase is collected, again washed with water and dried over MgSO 4 . After evaporation, the residue is purified by means of flash chromatography (ethyl acetate/hexane 1:3). The product is obtained as an isomer mixture in the form of a yellow oily-waxy substance. Example H6: l-(4-Chlorophenyl)-4-dimethylamino-l-(4-trifluoromethoxyphenyl)- 2,3-diaza-l,3-pentadiene (Compound 2.1 in Table 2) A solution of 0.85 g of 4-chloro-4'-trifluoromethoxybenzophenone hydrazone in 15 ml of toluene is treated with 0.66 g of N,N-dimethylacetamide dimethyl acetal. The mixture is subsequently refluxed for 18 hours. After the mixture has been cooled and the solvent evaporated completely, the brown residue is purified by means of flash chromatography (ethyl acetate/hexane 1:5). The title compound is obtained as an isomer mixture in the form of yellow crystals of m.p. 52-54°C. Example H7: 5-Ethanesulfonyl-l-(4-chlorophenyl)-l-(4-trifluoromethoxyphenyl)-2,3,5- triazapenta- 1 ,3-diene or 5-ethanesulfonyl- 1 -(4-chlorophenyl- 1 -(4-trifluoro- methoxyphenyl)-2,3,5-triazapenta-l,4-diene. (Compound 3.1 in Table 3) 0.75 g of l-ethanesulfonyl-l-aza-3-oxa-l-pentene and 0.85 g of N-ethyldiisopropylamine are added to a solution of 0.85 g of 4-chloro-4'-trifluoromethoxybenzophenone hydrazone in 15 ml of toluene. The mixture is stirred for 20 hours under reflux. After the mixture has been cooled, the solvent is evaporated completely and the residue purified by means of flash chromatography (ethyl acetate/hexane 1:2). The title compound is obtained as an isomer mixture in the form of a yellow wax. Example H8: 4-Bromodifluoromethoxy-4 ' -chlorobenzophenone 2.58 g of 80% sodium hydride in oil are added in three equally- sized portions at 25-30°C to a stirred solution of 25 g of 4-chloro-4'-hydroxybenzophenone in 150 ml of dimethylformamide. 27 g of dibromodifluoromethane are then added dropwise at 25 °C, and the mixture is stirred for 16 hours at room temperature. The reaction mixture is subsequently poured into 800 ml of H 2 O and extracted three times using in each case 300 ml of ethyl acetate. The organic phase is evaporated and the residue purified by column chromatography (silica gel; hexane/ethyl acetate 20:1). This gives white crystals of a melting point 52-55°C. Example H9: 4-Bromodifluoromethoxy-4'-chlorobenzophenone hydrazone 7.15 g of 4-bromodifluoromethoxy-4'-chlorobenzophenone, 5.45 g of hydrazine hydrate and 1.5 ml of glacial acetic acid are stirred for 6 hours at 60°C in 150 ml of ethanol. The reaction mixture is concentrated and the concentrate extracted using water and ethyl acetate. The organic phase is evaporated and the residue purified by column chromatography (silica gel; hexane/ethyl acetate 7:1). This gives yellowish crystals which melt at 45-49°C. Example H10: 4-Bromodifluoromethoxy-4'-chlorobenzophenone N-acetylhydrazone (Compound 1.27 in Table 1) 0.30 g of triethylamine is added dropwise at 20-25°C to a solution of 1.0 g of 4-bromodifluoromethoxy-4'-chlorobenzophenonehydrazone and 0.23 g of acetyl chloride in 20 ml of tetrahydrofuran, and the mixture is stirred for 90 minutes at room temperature. The reaction mixture is concentrated and the concentrate extracted using water and ethyl acetate. The organic phase is evaporated and purified by column chromatography (silica gel; hexane/ethyl acetate 3:1). This gives the product, which melts at 118-120°C.
