Certain hydrazone derivatives are proposed in the literature as insecticidally active ingre¬ dients in pesticides. The biological properties of those known compounds are not, however, entirely satisfactory in the area of pest control and, therefore, there is a need to provide further compounds having pesticidal properties, especially for the control of insects, ectoparasites and representatives of the order Acarina. This problem is solved according to the invention by the provision of the present compounds I.
Some of the compounds I may be in the form of tautomers. If, for example, R2 is H, corresponding compounds I, that is to say those having a -N(H)-C(R3)=X partial structure, may be in equilibrium with the respective tautomers having a -N=C(R3)-XH partial structure. Accordingly, hereinafter there is to be understood by compounds I, where appropriate, also corresponding tautomers, even if the latter are not specifically mentioned in every case.
The compounds I and, as the case may be, their tautomers may be in the form of salts.
Compounds I having at least one basic centre may form, for example, acid addition salts.
These are formed, for example, with strong inorganic acids, such as mineral acids, e.g.
sulfuric acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, such as unsubstituted or substituted, for example halo-substituted, Cjalkanecarboxylic acids, e.g. acetic acid, saturated or unsaturated dicarboxylic acids, e.g. oxalic, malonic, maleic, fumaric or phthalic acid, hydroxycarboxylic acids, e.g. ascorbic, lactic, malic, tartaric or citric acid, or benzoic acid, or with organic sulfonic acids, such as unsubstituted or substituted, for example halo-substituted, Cj-Calkane- or aryl-sulfonic acids, e.g.
methane- or p-toluene-sulfonic acid. Compounds I having at least one acid group may furthermore form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal salts and alkaline earth metal salts, e.g. 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, e.g. ethylamine, diethyl- amine, triethylamine or dimethylpropylamine, or a mono-, di- or tri-hydroxy-lower alkyl¬ amine, e.g. mono-, di- or tri-ethanolamine. Furthermore, corresponding internal salts may also be formed. Within the scope of the invention, agrochemically advantageous salts are preferred; also included, however, are salts that have disadvantages for agrochemical applications, for example salts that are toxic to bees and to fish, which can be used, for example, for the isolation and purification of free compounds I or their agrochemically acceptable salts. In view of the close relationship between the compounds I in free form and in the form of their salts, hereinbefore and hereinafter any reference to the free compounds I or their salts is to be understood as including also the corresponding salts or the free compounds I, respectively, where appropriate and expedient. The same applies to tautomers of compounds I and their salts.

Salts of compounds I can be prepared in a manner known per se. For example, acid addition salts of compounds I are obtained by treatment with a suitable acid or a suitable ion-exchange reagent, and salts with bases are obtained by treatment with a suitable base or a suitable ion-exchange reagent.
Salts of compounds I can be converted into free compounds I in customary manner: acid addition salts, for example, by treatment with a suitable basic agent or a suitable ion- exchange reagent, and salts with bases, for example, by treatment with a suitable acid or a suitable ion-exchange reagent.
Salts of compounds I can be converted into different salts of compounds I in a manner known per se: acid addition salts, for example, can be converted into different acid addition salts, for example by treatment of a salt of an inorganic acid, such as a hydro¬ chloride, 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 being formed, for example silver chloride, is insoluble and therefore separates from the reaction mixture.
Depending upon the procedure and the reaction conditions, compounds I having salt- forming properties can be obtained in free form or in the form of salts.
The compounds I, II, III and IV may be in the form of one of the possible isomers or in the form of a mixture thereof; for example, depending upon the number and the absolute and relative configuration of the asymmetric carbon atoms, they may be in the form of pure isomers, such as antipodes and/or diastereoisomers, or in the form of mixtures of isomers, such as mixtures of enantiomers, for example racemates, mixtures of diastereoisomers or mixtures of racemates; the invention relates both to the pure isomers and to all possible .2139465 mixtures of isomers and this is to be understood hereinbefore and hereinafter, even if stereochemical details are not specifically mentioned in every case.
Mixtures of diastereoisomers and mixtures of racemates of compounds I, II, HI and IV that are obtainable in accordance with the process - depending upon the starting materials and procedures chosen, - or by other means, can be separated into the pure diastereoisomers or racemates in known manner on the basis of the physico-chemical differences between the constituents, for example by fractional crystallisation, distillation and/or chromatography.
Mixtures of enantiomers, such as racemates, accordingly obtainable can be separated into the optical antipodes by known methods, for example by recrystallisation from an optically active solvent, by chromatography on chiral adsorbents, for example high- pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable micro¬ organisms, by cleavage with specific immobilised enzymes, or via the formation of inclusion compounds, for example using chiral crown ethers, in which case only one enantiomer is complexed.
Apart from by the separation of corresponding mixtures of isomers, it is possible according to the invention to obtain pure diastereoisomers or enantiomers also by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process of the invention with starting materials having correspondingly suitable stereochemistry.
Advantageously, the biologically more active isomer, for example enantiomer, or mixture of isomers, for example mixture of enantiomers, will be isolated or synthesised, insofar as the individual components have differing biological activity.
The compounds I, II, III and IV can also be obtained in the form of their hydrates and/or may include other solvents, for example solvents that have been used, where appropriate, for the crystallisation of compounds that are in solid form.
The invention relates to all those forms of the process according to which a compound obtainable as starting material or intermediate at any stage of the process is used as starting material and all or some of the remaining steps are carried out, or a starting material is used in the form of a derivative or a salt and/or its racemates or antipodes or, especially, is formed under the reaction conditions.

Suitable solvents are: aromatic hydrocarbons, preferably alkylbenzene fractions containing 8 to 12 carbon atoms, such as xylene mixtures or alkylated naphthalenes, aliphatic or cycloaliphatic hydrocarbons, such as cyclohexane, paraffins or tetrahydronaphthalene, alcohols, such as ethanol, propanol or butanol, glycols and their ethers and esters, such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetanol alcohol, strongly polar solvents, such N-methyl-2-pyrrolidone, dimethyl sulfoxide or N,N-di- methylformamide, water and vegetable oils or epoxidised vegetable oils, such as rape oil, castor oil, coconut oil or soybean oil or epoxidised rape oil, castor oil, coconut oil or soybean oil; and, where appropriate, silicone oils.
The solid carriers used, e.g. for dusts and dispersible powders, are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acids or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, such as pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are calcite or sand. In addition, a great number of granulated materials of inorganic or organic nature can be used, especially dolomite or pulverised plant residues.
Depending upon the nature of the compound of the invention or of the combination of that compound with other insecticides which is to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cyclo- aliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydro¬ carbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols. Further suitable non-ionic surfactants are water-soluble adducts of polyethylene oxide with poly¬ propylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Repre¬ sentative examples of non-ionic surfactants are nonylphenol polyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxy- ethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan, e.g. polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants.
Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C8-C22alkyl radical and, as further substituents, unsubstituted or halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates. Examples are stearyltrimethyl- ammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide.
Both so-called water-soluble soaps and water-soluble synthetic surface-active compounds are suitable anionic surfactants. Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C10-C22), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tall oil; mention may also be made of fatty acid methyltaurin salts. More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and generally contain a C8-C22alkyl radical, which also includes the alkyl moiety of acyl radicals; there may be mentioned by way of example the sodium or calcium salt of ligno- 30- sulfonic acid, of dodecyl sulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids. These compounds also comprise the salts of sulfated or sulfonated fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing approximately 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanol- ammonium salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid or of a condensate of naphthalenesulfonic acid and formaldehyde. Also suitable are corres¬ ponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 mol of ethylene oxide, or phospholipids.
The surfactants listed above are to be regarded merely as examples; many more surfactants customarily employed in formulation technology and suitable for use according to the invention are described in the relevant literature.
The pesticidal compositions usually comprise 0.1 to 99 %, preferably 0.1 to 95 %, of a compound of the invention or of a combination of that compound with other insecticides, and 1 to 99.9 %, preferably 5 to 99.9 %, of a solid or liquid adjuvant, it generally being possible for 0 to 25 %, preferably 0.1 to 20 %, of the composition to be surfactants (percentages are by weight in each case). Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations which have considerably lower active ingredient concentrations. Typical concentration rates are from 0.1 to 1000 ppm, preferably from 0.1 to 500 ppm, active ingredient. The application rates per hectare are generally from 1 to 1000 g of active ingredient per hectare, preferably from 25 to 500 g/ha.
Preferred formulations have especially the following composition (throughout, percentages are by weight):
Emulsifiable concentrates:

0.5 to 30 %, preferably 3 to 15 % 99.5 to 70 %, preferably 97 to 85 % The compositions may also comprise other adjuvants, such as stabilisers, e.g. vegetable oils or epoxidised vegetable oils (e.g. epoxidised coconut oil, rape oil or soybean oil), antifoams, e.g. silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, as well as fertilisers or other active ingredients for obtaining special effects.

Preparation Examples General Remarks The compounds are obtained as isomeric mixtures usually in the form of viscous oils.
They can be purified by column chromatography. NMR spectra and elemental analyses confirm the required structures.
Example PI: 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone-N-methylhydrazone 180 g of 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone are heated under reflux in 600 ml of absolute alcohol with 29.6 g of glacial acetic acid and 31.8 g of methyl- hydrazine for one day. The solution is then concentrated by evaporation in vacuo, and the residue is taken up in approximately 150 ml of toluene and again concentrated by evapora¬ tion. The oil which remains is taken up in hexane/ethyl acetate 9:1 and the solution is 32- stirred over magnesium sulfate and sodium bicarbonate for approximately 30 minutes.
The salts are removed by filtration and the filtrate is concentrated by evaporation in vacuo.
The title compound remains behind in the form of a yellow oil.
Example P2 : 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone-N-formyl-N-methyl- hydrazone (compound 1.1 in Table 1) With the exclusion of moisture, 150 g of sodium formate are introduced into approxi¬ mately 125 ml of ether with stirring, and 147 g (1.87 mol) of acetyl chloride are added dropwise thereto at a reaction temperature of 0oC. The reaction mixture is then stirred for several hours at room temperature, sodium chloride is removed by filtration, and the residue is washed with dry ether to yield a solution of approximately 1.87 mol of formyl acetate in ether.
A portion of that solution, containing 0.49 mol of formyl acetate, is added dropwise to a solution of 184 g of the hydrazone from Example PI in 200 ml of ether. The reaction is complete after a few hours. Ice-water is added, the organic layer is collected, washed once more with water, dried over magnesium sulfate and filtered, and the filtrate is concentrated by evaporation and purified by column chromatography on silica gel using ethyl acetate/hexane 1:9 as eluant. The product is obtained as an isomeric mixture in the form of an oily-waxy mass.

After approximately 1 hour, the reaction solution is filtered and washed with a small amount of ethyl acetate, the filtrate is concentrated by evaporation in vacuo, and the 33- residue is purified on a column of silica gel using ethyl acetate/hexane 1:9 as eluant. The product is obtained in the form of a sticky crystalline mass.

After 15 minutes, the reaction mixture is poured onto ice-water, and the organic layer is separated off and, after being dried over magnesium sulfate, is concentrated by evapora¬ tion in vacuo. Purification by column chromatography on silica gel using ethyl acetate/- hexane (1:2) as eluant yields the title compound having a melting point of 112-1160C.
