In the literature, certain phenylhydrazone derivatives are proposed as active ingredients in pesticides. The biological properties of these known compounds, however, are not fully satisfactory in the field of pest control, which is why there is a need to produce further compounds with pesticidal properties, especially for the control of insects and members of the order acarina; this problem is solved according to the invention with the development of the present compounds of formula (I).

Some compounds of formula (I) comprise asymmetrical carbon atoms, as a result of which the compounds may occur in an optically active form. Owing to the presence of the C=N double bond, the compounds may occur in E and Z isomeric forms. Atropisomers of the compounds may also occur. Formula (I) should encompass all these possible isomeric forms and mixtures thereof, for example racemates or mixtures of E/Z isomers.

The general terms used hereinbefore and hereinafter have the following meanings, unless defined otherwise.

Groups and compounds containing carbon comprise, unless defined otherwise, in each case 1 to 8 inclusive, preferably 1 to 6 inclusive, more particularly 1 to 4 inclusive, especially 1 or 2, carbon atoms.

Alkyl-as a group per se and as a structural component of other groups and compounds, such as alkyl halide, alkoxy or alkylthio-is, in each case with due consideration to the number of carbon atoms in the group or compound concerned, either straight-chained, i. e. methyl, ethyl, propyl, butyl, pentyl or hexyl, or branched, e. g. isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl, neopentyl or isohexyl.

Alkenyl-as a group per se and as a structural component of other groups and compounds, such as alkenoxy, alkenyl halide or alkenoxy halide-is, in each case with due consideration to the number of carbon atoms in the group or compound concerned, either straight-chained, e. g. vinyl, 1-methylvinyl, allyl, 1-butenyl oder 2-hexenyl, or branched, such as isopropenyl.

Alkinyl-as a group per se and as a structural component of other groups and compounds, such as alkinyl halide-is, in each case with due consideration to the number of carbon atoms in the group or compound concerned, either straight-chained, e. g. propargyl, 2- butinyl or 5-hexinyl, or branched, such as 2-ethinylpropyl or 2-propargylisopropyl.

C3-C6cycloalkyl is cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl.

Aryl is phenyl or naphthyl, especially phenyl.

Bicyclic heteroaryl is taken to mean a radical which may independently contain one or more heteroatoms only in one ring-such as for example in quinolinyl, quinoxalinyl, indolinyl, benzothiophenyl or benzofuranyl-as well as in both rings-such as for example in pteridinyl or purinyl.

Halogen-as a group per se and as a structural component of other groups and compounds, such as alkyl halide, alkenyl halide and alkinyl halide-is fluorine, chlorine, bromine or iodine, especially fluorine, chlorine or bromine, more especially fluorine or chlorine, and quite particularly chlorine.

Halogen-substituted groups and compounds containing carbon, such as alkyl halide, alkenyl halide or alkinyl halide, may be partly halogenated or perhalogenated, where in the case of repeated halogenation the halogen substituents may be the same or different. Examples of alkyl halide-as a group per se and as a structural component of other groups and compounds, such as alkenyl halide-are methyl substituted once to three times by fluorine, chlorine and/or bromine, such as CHF2 or CF3; ethyl substituted once to five times by fluorine, chlorine and/or bromine, such as CH2CF3, CF2CF3, CF2CC13, CF2CHC12, CF2CHF2, CF2CFC12, CF2CHBr2, CF2CHCIF, CF2CHBrF or CCIFCHCIF; propyl or isopropyl substituted once to seven times by fluorine, chlorine and/or bromine, such as CH2CHBrCH2Br, CF2CHFCF3, CH2CF2CF3 or CH (CF3) 2; and butyl or one of the isomers thereof substituted once to nine times by fluorine, chlorine and/or bromine, such as CF (CF3) CHFCF3 or CH2 (CF2) 2CF3. Alkenyl halide is for example CH2CH=CHCI, CH2CH=CC12, CH2CF=CF2 or CH2CH=CHCH2Br. Alkinyl halide is for example CH2C-=CF, CH2C=CCH2CI or CF2CF2C=-CCH2F.

Some compounds of formula (I) may, as is familiar to persons skilled in the art, occur as tautomers, especially if R2 is H. Accordingly, any reference to compounds of formula (I) hereinbefore and hereinafter is understood to include also their corresponding tautomers, even if the latter are not specifically mentioned in each case.

Compounds of formula (I) which show 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. perchloric acid, sulfuric acid, nitric acid, nitrous acid, a phosphoric acid or a hydrogen halide, with strong organic carboxylic acids, such as C1-C4alkanecarboxylic acids substituted if appropriate by halogen, e. g. acetic acid, such as dicarboxylic acids unsaturated if appropriate, e. g. oxalic, malonic, succinic, maleic, fumaric or phthalic acid, such as hydroxycarboxylic acids, e. g. ascorbic, lactic, malic, tartaric or citric acid, or benzoic acid, or with organic sulfonic acids, typically C1-C4alkanesulfonic or arylsulfonic acids substituted where appropriate for example by halogen, e. g. methanesulfonic or p- toluenesulfonic acid. In a broader sense, compounds of formula (I) with at least one acid group can form salts with bases. Suitable salts with bases are for example metal salts, typically alkali or 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. ethyl, diethyl, triethyl or dimethylpropylamine, or a mono-, di-or trihydroxy-lower alkylamine, e. g. mono-, di-or triethanolamine. Corresponding internal salts where appropriate may also be formed. Compounds of formula (I) in free form are hereinbefore and hereinafter taken to imply also their corresponding salts, and the salts where applicable are taken to mean also the free compounds of formula (I). The same applies for tautomeric derivatives of compounds of formula (I) and salts thereof. In each case, the free form is generally preferred.

The compounds of formulae (I), (lla), (llb) und (VIII) may be present in the form of one of the possible isomers or as a mixture thereof, depending for example on the number and the absolute and relative configuration of the asymmetric carbon atoms as pure isomers, such as enantiomers and/or diastereomers or isomer mixtures, such as mixtures of enantiomers, for example racemates; the invention relates both to the pure isomers and to all possible isomeric mixtures, and is hereinbefore and hereinafter understood as doing so, even if stereochemical details are not specifically mentioned in every case.

Diastereomer mixtures and racemate mixtures of compounds of formulae (I), (lla), (Ilb) and (VIII), obtainable as described in the method-depending on the starting materials and working procedures selected-or by other means, can, owing to the physicochemical differences of the constituents, be separated in known manner into the pure diastereomers or racemates, for example by fractionated crystallization, distillation and/or chromatography.

The resolution of correspondingly obtainable mixtures of enantiomers, such as racemates, can be achieved by known methods, for example by recrystallization from an optically active solvent, by chromatography on chiral adsorbents, e. g. high-pressure liquid chromatography (HPLC) on acetyl cellulose, by the use of suitable microorganisms, by cleavage with specific immobilized enzymes, through the formation of inclusion compounds, e. g. using chiral crown ether, wherein only one enantiomer is complexed.

According to the invention, apart from isolation of corresponding isomer mixtures, generally known methods of diastereoselective or enantioselective synthesis can also be applied to obtain pure diastereomers or enantiomers, e. g. by carrying out the method of the invention using educts with correspondingly suitable stereochemistry.

It is of advantage to isolate or synthesize the biologically more active isomer in each case, e. g. enantiomer or mixture of isomers, e. g. enantiomer mixture, if the individual components show differences in biological efficacy.

Compounds of formula (I), (lla), (Ilb) und (VIII) can also be obtained in the form of their hydrates and/or also can include other solvents used for example where necessary for the crystallization of compounds present in solid form.

The invention relates to all those forms of the method, according to which one starts from a compound obtainable as a primary material or an intermediate at any stage of the method and carries out all or some of the missing steps, or uses, or-especially under the reaction conditions-produces a starting material in the form of a derivative or a salt and/or its racemate or enantiomer.

In the method of the present invention, the starting materials and intermediates used are preferably those that lead to the compounds of formula (I) described at the beginning as being especially useful.

The invention relates in particular to the manufacturing processes described in Examples H1, H2, H4 and H5.

Starting materials and intermediate products used according to the invention for the preparation of compounds of formula (I), and in particular the compounds of formulae (II), (III), (IV) and (VIII), which are new, and their use and methods for their preparation likewise form an object of the invention.

Compounds of formulae (lla), (Ilb) and (VIII) as well as the use thereof for the preparation of compounds of formula (I) represent a further object of the invention.

The compounds of formulae (III) to (VI) and (IX) are known or can be prepared according to known methods.

A further object of the invention is a method for controlling pests using a compound of formula (I), wherein A,, A2 and R2 have the same meaning as defined hereinbefore for formula (I).

The compounds of formula (I) according to the invention are active substances of preventive and/or curative merit for use in pest control and offer a very favourable spectrum of biocidal activity with favourable tolerability in warm-blooded animals, fish, and plants even at low concentrations. The compositions according to the invention are active against all or individual development stages of animal pests showing normal sensitivity, and also of those showing resistance, for example insects or members of the order acarina. The insecticidal, ovicidal, and/or acaricidal effect of the compositions of the invention can manifest itself directly, i. e. killing the pests either immediately or after some time has elapsed, for example when moulting occurs, or the eggs thereof, or indirectly, e. g. reducing the number of eggs laid and/or the hatching rate, good efficacy corresponding to a destruction rate (mortality) of at least 50 to 60%.

The animal pests include for example: Members of the orders lepidoptera, coleoptera, orthoptera, isoptera, psocoptera, anoplura, mallophaga, thysanoptera, heteroptera, homoptera, hymenoptera, diptera, siphonaptera, thysanura and acarina; especially preferred is the control of pests of the genera and species which are described in EP-A-736'252, and which are included here by reference.

Pests of said type which occur on plants, especially on crops and ornamentals in agriculture, horticulture and forestry, or on parts of such plants, such as fruits, blooms, leaves, stems, tubers or roots, can be controlled, i. e. kept in check or eradicated, using the active ingredients of the invention, this protection remaining for parts of some plants whose growth does not occur until later.

Target crops within the scope of this application include especially cereals, such as wheat, barley, rye, oats, rice, corn or sorghum; beet, such as sugar beet or fodder beet; fruit, e. g. pomes, drupes and soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, e. g. strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soybean; oleaginous fruits, such as rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans or groundnuts; cucumber plants, such as pumpkins, cucumbers or melons; fibrous plants, such as cotton, flax, hemp or jute; citrus fruits, such as oranges, lemons, grapefruit or mandarins; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or paprika; lauraceae, such as avocado, cinnamon or camphor; and tobacco, nuts, coffee, aubergines, sugar cane, tea, pepper, vines, hops, banana plants, natural rubber plants and ornamentals.

The active ingredients of the invention are especially suitable for the control of insects and members of the order acarina, in particular crop-eating and damaging insects, such as Anthonomus grandis, Diabrotica balteata, Heliothis virescens larvae, Plutella xylostella and Spodoptera littoralis larvae, and spider mites, such as Tetranychus spp., in cultivated plants of cotton, fruit, maize, soya, rape and vegetables.

Other indication areas for the active ingredients of the invention are the protection of stored products and stores and of material and, in the hygiene sector, in particular the protection of domestic animals and livestock against pests of said type.

The invention therefore relates also to pesticides which comprise a compound of formula (I), wherein A,, A2 and R2 have the same meaning as defined hereinbefore for formula (I), with the exception of 1-phenylhydrazono-2-nitriloethylbenzene, such as emulsifiable concentrates, suspension concentrates, ready-to-spray or ready-to-dilute solutions, coatable pastes, dilute emulsions, spray powders, soluble powders, dispersible powders, wettable powders, dusts, granulates or encapsulations in polymeric substances (chosen in accordance with the intended objectives and prevailing circumstances), comprising at least one active ingredient of the invention.

In these compositions, the active ingredient is employed in pure form, the solid active ingredients in a specific particle size, or preferably together with-at least-one of the adjuvants conventionally used in the art of formulation, such as extenders, e. g. solvents or solid carriers, or surface-active compounds (surfactants).

Suitable adjuvants, such as solvents, solid carriers, surface-active compounds, non-ionic surfactants, cationic surfactants, and anionic surfactants in the compositions used according to the invention, are the same as those which are described in EP-A-736'252 (CASE 20400) and which are included in the present object of the invention by reference.

As a rule, the compositions comprise 0.1 to 99%, especially 0.1 to 95%, of active ingredient and 1 to 99.9%, especially 5 to 99.9%, of-at least-one solid or liquid adjuvant, wherein 0 to 25%, especially 0.1 to 20%, of the composition may as a rule be surfactant (% in each case meaning percent by weight). Whereas concentrated compositions tend to be preferred for commercial goods, the end consumer as a rule uses dilute compositions which have substantially lower concentrations of active ingredient. Preferred compositions are thus composed in particular as described in EP-A-736'252.

The activity of the compositions of the invention can be substantially broadened and adapted to prevailing circumstances by adding other insecticidal, acaricidal, and/or fungicidal substances. Additional active ingredients are, for example, substances from the following classes: organophosphorus compounds, nitrophenols and derivatives, formamidine, urea, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions of the invention can also comprise other solid or liquid adjuvants, such as stabilizers, e. g. vegetable oils, epoxidized where appropriate (e. g. epoxidized coconut oil, rapeseed oil or soya oil), antifoams, e. g. silicone oil, preservatives, viscosity modulators, binders and/or tackifiers, and also fertilizers or other active ingredients to achieve specific effects, e. g. acaricides, bactericides, nematocides, molluscicides or selective herbicides.

The compositions of the invention are prepared in a known manner, in the absence of adjuvants, for example, by grinding and/or sieving a solid active ingredient or active ingredient mixture, e. g. to a specific particle size, and in the presence of at least one adjuvant, for example, by intimately mixing and/or grinding the active ingredient or the mixture of active ingredients with the adjuvant (s). These methods for preparing compositions of the invention and the use of compounds of formula (I) for preparing these compositions likewise form an object of the invention.

The methods of application for the compositions, i. e. the methods of controlling pests of said type, such as spraying, atomizing, dusting, coating, dressing, scattering or pouring (chosen in accordance with the intended objectives and prevailing circumstances), and the use of the compositions for controlling pests of said type are further objects of the invention.

Typical concentrations of active ingredient are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm. The rates of application are generally 1 to 2000 g of active ingredient (a. i.) per hectare (ha = approximately 2.471 acres), especially 10 to 1000 g a. i./ha, and preferably 20 to 600 g a. i./ha.

A preferred method of application for crop protection is to apply the active ingredient to the foliage of the plants (leaf application), the number of applications and the rate of application depending on the intensity of infestation by the pest in question. However, the active ingredients can also penetrate the plant through the roots via the soil (systemic action) by impregnating the locus of the plant with a liquid composition, or by applying the compounds in solid form to the soil, e. g. in granular form (soil application). With paddy rice cultures, granules may be metered into the flooded paddy field.

The compositions of the invention are also suitable for protecting plant propagation material, e. g. seeds, such as fruits, tubers or grains, or plant seedlings, from fungal infections and animal pests. The propagation material can be treated with the composition before the start of cultivation, seeds for example being dressed before they are sown. The active ingredients of the invention can also be applied to seeds (coating) by either soaking the seeds in a liquid composition or coating them with a solid composition. The composition can also be given when the propagation material is introduced to the place of cultivation, e. g. when the seeds are sown in the seed furrow. The treatment procedures for plant propagation material and the propagation material thus treated are further objects of the invention.

The invention is illustrated by the following examples. They do not impose any limitation on the invention. Temperatures are given in degrees celsius.

Preparative examples Example H1: Preparation of 4-nitrobenzoic acid-N'- (2,6-dichloro-4-trifluoromethylphenyl)- hydrazide of formula A solution of 35.85 g 4-nitrobenzoyl chloride in 150 ml dichloromethane is added dropwise over a period of about 60 minutes to 45.1 g 2,6-dichloro-4-trifluoromethylphenylhydrazine in 1000 ml dichloromethane while stirring at 0 to 5°C, and the stirring is then continued for a further 60 minutes at room temperature. For 20 minutes the mixture is vigorously stirred while 20.4 g triethylamine is fed in. Stirring is then continued for 3 hours at room temperature. The organic phase is washed three times with 500 ml of water each time, dried on sodium sulfate and the solvents removed in the rotary evaporator. After recrystallization of the residue from toluene, the title product is obtained at a melting point of 188-190 °C.

Example H2: Preparation of 4- {1- [ (2,6-dichloro-4-trifluoromethylphenyl) hydrazono]- chloromethyl}-nitrobenzene of formula To a solution of 69.3 g 4-nitrobenzoic acid-N'- (2,6-dichloro-4-trifluoromethylphenyl)- hydrazide in 600 ml toluene, 33.9 g thionyl chloride is added dropwise while stirring at room temperature. The mixture is then heated to 105°C and stirred for 6 hours. After cooling, the mixture is concentrated to dryness by evaporation on the rotary evaporator and the residue crystallized out from toluene. The title compound is obtained at a melting point of 117- 118°C (compound 1.20).

The reaction mixture is stirred for 18 hours at room temperature and then poured onto 6 I of ice water. The precipitate is filtered, washed three times with water, dissolved in ethyl acetate and washed with 15% NaCI solution. The organic phase is dried, filtered over sodium sulfate, and concentrated to dryness by evaporation on the rotary evaporator. The residue is crystallized out from toluene. This yields the title compound with a melting point of 160-161 °C.
