EP-A-0 347 488, EP-A-0 372 263, EP-A-0 426 948, EP-A-0 434 940 and EP-A-0 492 171 propose cyanophenylpyrrole derivatives as acaricidal and insecticidal active ingredients in pesticides. However, the biological properties of the compounds described in these publications are not entirely satisfactory in the pest control sector, and this is why it has been found necessary to provide other compounds having pest-controlling properties, in particular for the control of insects and of representatives from the order of the Acarina, and this object is achieved according to the invention by providing the present compounds I which, surprisingly, are additionally also suitable for controlling phytopathogenic fungi. 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 perchloric acid, sulfuric acid, nitric acid, nitrous acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, for example unsubstituted or halogen-substituted CrC4alkyl carboxylic acids, for example acetic acid, or unsaturated or saturated dicarboxylic acids, for example oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid or phthalic acid, or hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or benzoic acid, or with organic sulfonic acids for example C1-C4alkyl - or arylsulfonic acids which are unsubstituted or substituted for example by halogen, for example methane- or p-toluenesulfonic acid. Furthermore, compounds I having at least one acidic group can form salts with bases. Suitable salts with bases are, for example, metal salts such as alkali metal salts or alkaline earth metal salts, for example sodium salts, potassium salts 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, corresponding internal salts may possibly be formed. Preferred within the scope of the invention are agrochemically advantageous salts; however, the invention also comprises 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 usable salts. Due to the close relation between the compounds I in free^orna-af^rrti^T^i^jrf tl^eir salts, the free compounds I, or salts _ 2 JUN 1995 2440g -3- thereof, which are mentioned hereinbefore and hereinafter are also to be understood as meaning analogously and expediently, where appropriate, the corresponding salts, or the free compounds I, respectively.

What has been said hereinbefore for salts of compounds I applies analogously to starting materials listed hereinbefore and hereinafter with regard to salts thereof. The reactions described hereinbefore and hereinafter are carried out in a manner known per se, for example in the absence or, conventionally, in the presence of a suitable solvent or diluent or a mixture of these, the process being carried out, depending on the circumstances, with cooling, at room temperature or with heating, for example in a temperature range of approximately -80°C to the boiling point of the reaction medium, preferably from approximately -20°C to approximately +150°C, and, if required, in a sealed container, under pressure, under an inert gas atmosphere and/or under anhydrous -9- 24 4 0 conditions. Particularly advantageous reaction conditions can be found in the examples. The starting materials listed hereinbefore and hereinafter which are used for the preparation of the compounds I, in free form or in salt form, are known or can be prepared by methods known per se, for example according to the instructions below. Variant a-): Examples of suitable halogenating agents are elemental halogens, such as elemental chlorine, bromine or iodine, sulfuryl halides such as sulfuryl chloride or sulfuryl bromide, or N-halosuccinimides, such as N-chlorosuccinimide or N-bromosuccinimide.

Examples of such solvents or diluents which may be mentioned are; aromatic, aliphatic and alicyclic hydrocarbons and halohydrocarbons such as benzene, toluene, xylene, mesitylene, tetralin, chlorobenzene, dichlorobenzene, bromobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, tetrachloromethane, dichloroethane, trichloroethene or tetrachloroethene; esters such as ethyl acetate; ethers such as diethyl ether, diisopropyl ether, dibutyl ether, tert-butyl methyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol dimethyl ether, dimethoxydiethyl ether, 24 4 0 9 5 - l'l - tetrahydrofuran or dioxane; ketones such as acetone, methyl ethyl ketone or methyl isobutyl ketone; alcohols, such as methanol, ethanol, propanol, isopropanol, butanol, ethylene glycol or glycerol; amides such as N,N-dimethylformamide, N,N-diethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone or hexamethylphosphoric triamide; nitriles such as acetonitrile; and sulfoxides such as dimethyl sulfoxides. If the reaction is carried out in the presence of a base, bases which are employed in excess such as triethylamine, pyridine, N-methylmorpholine or N,N-diethylaniline, can also act as solvents or diluents. The reaction is advantageously carried out in a temperature range of from approximately 0°C to approximately +180°C, preferably from approximately +10°C to approximately +130°C, in many cases in the range between room temperature and the reflux temperature of the reaction mixture. Variant c): Examples of suitable halogenating agents are of the type described in variant a). Examples of suitable bases for facilitating the reaction with the halogenating agent are of the type described in variant a). Examples of suitable radical initiators are peroxo compounds, such as dibenzoyl peroxide or di-tert.-butyl peroxide, azo compounds, such as 2,2'-azobisisobutyronitrile, and light. The reactants can be reacted with each other as such, i.e. without the addition of a solvent or diluent, for example in the melt. However, the addition of an inert solvent or diluent or a mixture of these is advantageous in most cases. Examples of such solvents or diluents which may be mentioned are of the type described in variant b). The reaction is advantageously carried out in a temperature range of from approximately 0°C to approximately +180°C, preferably from approximately +10°C to approximately +130°C, in many cases in the range between room temperature and the reflux temperature of the reaction mixture. It is possible to prepare different products of the formula I when variant c) is carried out, depending on the number of equivalents of halogenating agent used. At least two equivalents of halogenating agent have to be used. By means of the first equivalent the ? A A 0 Q F - 12- dihydropyxrole derivative VII is oxidised and the corresponding pyrrole intermediate is thus obtained ("compound A")- By means of the second equivalent of halogenating agent the halogen substituent R2 is introduced into the 4-position of the pyrrole ring of the compound A, thus yielding the corresponding compound I, wherein R4 is methyl ("compound B"). In order to obtain the corresponding compound I, wherein R4 is a group R2CH2-, i. e. in order to mono-halogenate the methyl group R4 of the compound B, a third equivalent of halogenating agent is needed. The term "equivalent" is to be understood in this paragraph in such a way, that it comprises not only the exact amount corresponding to the exact equivalent, but also a certain range, for example approximately 10%, above and below this exact amount. It is possible to isolate the compound A and/or the compound B, but preferably the reaction is carried out in the form of a one-pot-reaction without isolation of the compounds A and B. It is also possible to add the whole amount of halogenating agent at the beginning of the reaction, but preferably the halogenating agent is added portionwise, for example in several portions of one equivalent each. The mono-halogenation of the methyl group R4 of compound B is preferably carried out in the presence of a radical initiator. The compounds II which are used as educts in process variant a), in free form or in salt form, are novel and also form a subject of the invention. Particularly preferred compounds of the formula II within the scope of the invention are those mentioned in Examples HI A further subject of the invention is the process for the preparation of the compounds of the formula II, in free form or in salt form, which comprises, for example, d) to prepare a compound of the formula II in which R4 is hydrogen, or a salt thereof, reacting a compound of the formula O in which R1? R3 and n are as defined in formula I, or a salt of such a compound, with 2-chloroacrylonitrile, preferably in a high-boiling polar solvent such as nitromethane, and at the reflux temperature of the reaction mixture, or and H6. (IV) e) to prepare a compound of the formula II in which R4 is other than hydrogen, or a salt of 24 4 0 9 - 13 - such a compound, reacting a compound of the formula II which can be obtained, for example, in accordance with variant d), and in which R4 is hydrogen, or a salt of such a compound, preferably in the presence of a base, for example of the type given in the case of variant a), with a compound of the formula X-R4 (HI) which is known or which can be prepared analogously to corresponding known compounds and in which R4 is as defined in formula I with the exception of hydrogen, and X is a leaving group, for example of the type given in variant b), or, if appropriate, with a salt thereof, and, if desired, in each case converting a compound of the formula II which can be obtained according to the process or by a different route, in free form or in salt form, into a different compound of the formula n, resolving an isomer mixture which can be obtained according to the process, and isolating the isomer desired, and/or converting a free compound of the formula II which can be obtained according to the process into a salt, or converting a salt of a compound of the formula II which can be obtained according to the process into the free compound of the formula II or into a different salt. The compounds IV, in free form or in salt form, are known or can be prepared analogously to known compounds, for example by reacting a compound of the formula HOOC- CH—V \ NH2 <R> <V>' which is known or which can be prepared analogously to corresponding known compounds and in which R3 and n are as defined in formula I, or a salt of such a compound, with a compound of the formula O RrCF2-C-0-C-CF2-Ri (VI), which is known or which can be prepared analogously to corresponding known compounds and in which Rj is as defined in formula I, the process preferably being carried out under atmospheric pressure, if appropriate in the presence of a solvent or diluent, for example of the type given in the case of variant a), in particular in the presence of a high-boiling aromatic hydrocarbon such as toluene, xylene, mesitylene or tetralin, and at temperatures between 70°C and 200°C, in particular between 120°C and 180°C, preferably at the boiling point of the reaction mixture. The compounds VII which are used as educts in process variant c), in free form or in salt 24 4 { - 14- form, are -novel and also form a subject of the invention. A further subject of the invention is the process for the preparation of the compounds of the formula VII, in free form or in salt form, which comprises, for example, f) reacting a compound of the formula O COOH in which Rlt R3 and n are as defined in formula I, or a salt of such a compound, with acrylonitrile, preferably in a high-boiling polar solvent, such as acetonitrile, in the presence of an acid anhydride, such as acetic anhydride, and at the reflux temperature of the reaction mixture, and, if desired, converting a compound of the formula VII which can be obtained according to the process or by a different route, in free form or in salt form, into a different compound of the formula VII, resolving an isomer mixture which can be obtained according to the process, and isolating the isomer desired, and/or converting a free compound of the formula VII which can be obtained according to the process into a salt, or converting a salt of a compound of the formula VII which can be obtained according to the process into the free compound of the formula VII or into a different salt. The compounds VIII are known or can be prepared analogously to corresponding known compounds. A compound I, II or VII which can be obtained according to the process or by a different route can be converted into a different compound I, II or VII in a manner known per se by replacing one or more substituents of the starting compound I, II or VII in the customary manner by (an)other substituent(s) according to the invention. For example, - hydroxyl groups (as substituents of alkyl groups R4) can be alkylated to give alkoxy groups (as substituents of alkyl groups R4); - halogen R3 can be introduced into unsubstituted positions of the phenyl ring; - mercapto groups R3 and/or R4 can be oxidised to give sulfinyl or sulfonyl groups R3 and/or R4 or sulfinyl groups R3 and/or R4 can be oxidised to give sulfonyl groups R3 '3 244095 -15- and/orR4; - methyl groups R4 can be mono-halogenated to give mono-halomethyl groups R4; or - the halogen substituent present in mono-halomethyl groups R4 can be replaced by an alkoxy group to give a mono-alkoxymethyl group R4. Depending on the choice of the reaction conditions and starting materials which are suitable in each case, it is possible to replace, in one reaction step, only one substituent by a different substituent according to the invention, or a plurality of substituents can be replaced by other substituents according to the invention in the same reaction step. Salts of compounds I, n or VII can be prepared in a manner known per se. For example, acid addition salts of compounds I, II or VII are obtained by treatment with a suitable acid or a suitable ion-exchanger reagent, and salts with bases are obtained by treatment with a suitable base or a suitable ion-exchanger reagent. Salts of compounds I, II or VII can be converted in the customary manner into the free compounds I, II or VII, respectively, for example acid addition salts by treatment with a suitable basic agent or a suitable ion-exchanger reagent and salts with bases for example by treatment with a suitable acid or a suitable ion-exchanger reagent. Salts of compounds I, II or VII can be converted into other salts of compounds I, II or VH, respectively, in a manner known per se, for example acid addition salts into different acid addition salts, for example by treatment of a salt of an inorganic acid such as a hydrochloride with a suitable metal salt such as a sodium salt, barium salt 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 so precipitates from the reaction mixture. Depending on the procedure or reaction conditions, the compounds I, II or VII which have salt-forming properties can be obtained in free form or in the form of salts. The compounds I, II or VII, in free form or in salt form, can exist in the form of one of the isomers which are possible or as a mixture thereof, for example 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, depending, for example, on the number, absolute and relative configuration of asymmetric carbon atoms in the 24 4 0 -16- molecule and/or depending on the configuration of non-aromatic double bonds in the molecule; the invention relates to the pure isomers as well as to all isomer mixtures which are possible and is to be understood accordingly hereinbefore and hereinafter, even when stereochemical details are not mentioned specifically in each case. Diastereomer mixtures and racemate mixtures of compounds I, II or VII, in free form or in salt form, which can be obtained according to the process - depending on the choice of starting materials and procedures - or by other routes can be resolved in the known manner based on the physicochemical differences of the components to give the pure diastereomers or racemates, for example by fractional crystallisation, distillation and/or chromatography. Enantiomer mixtures such as racemates which can be obtained accordingly can be resolved by known methods to give the optical antipodes, 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 microorganisms, by cleavage with specific immobilised enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer is sequestered, or by conversion into diastereomeric salts, for example by reacting a basic end product racemate with an optically active acid such as carboxylic acid, for example camphoric acid, tartaric acid or malic acid, or sulfonic acid, for example camphorsulfonic acid, and resolution of the resulting diastereomer mixture, for example on the basis of their different solubilities by fractional crystallisation to give the diastereomers from which the enantiomer desired can be liberated by the action of suitable agents, for example basic agents. In addition to the resolution of conresponding isomer mixtures, pure diastereomers, or enantiomers, can also be obtained according to the invention by generally known methods of diastereoselective, or enantioselective, synthesis, for example by carrying out the process according to the invention with educts having a suitable stereochemistry. It is advantageous to isolate, or synthesise, in each case the biologically more active isomer, for example enantiomer or diastereomer, or isomer mixture, for example enantiomer mixture or diastereomer mixture, if the individual components have different biological activities. 24409 - 17- The compounds I, II or VII, in free form or in salt form, can also be obtained in the form of their hydrates and/or can include other solvents, for example those which can be used for the crystallisation of compounds in solid form. The invention relates to all those embodiments of the process in which a compound which can be obtained in any step of the process is used as starting material or intermediate and all, or some, of the missing steps are carried out, or in which a starting material in the form of a derivative or salt and/or racemates or antipodes thereof are used or, in particular, formed under the reaction conditions. It is preferred to use those starting materials and intermediates, in each case in free form or in salt form, in the process of the present invention which lead to the compounds I or salts thereof 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 H6. Another subject of the invention is novel starting materials and intermediates, in each case in free form or in salt form, which are used according to the invention for the preparation of the compounds I or salts thereof, a process for their preparation, and their use as starting materials and intermediates for the preparation of the compounds I; in particular, this applies to the compounds II and VII.

The active ingredients according to the invention allow the control, i.e. reduction or destruction, of pests of the abovementioned type which are found in particular on plants, especially on useful plants and ornamentals in agriculture, in horticulture and in forestry, or on parts of such plants, such as fruits, flowers, foliage, stalks, tubers or roots, and in some cases the protection against these pests extends to parts of plants which are formed at a later point in time. Suitable target crops 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 soybeans; oil crops such as oil-seed rape, mustard, poppy, olives, sunflowers, coconut, castor-oil plant, cacao or groundnuts; cucurbits such as pumpkins, cucumbers or melons; fibre plants such as cotton, flax, hemp or jute; citrus fruit such as oranges, lemons, grapefruit or tangerines; vegetables such as spinach, lettuce, asparagus, cabbage species, carrots, onions, tomatoes, potatoes or bell peppers; Lauraceae such as avocado, cinnamonium or camphor; and also tobacco, nuts, coffee, egg plants, sugar cane, tea, pepper, vines, hops, Musaceae, latex plants and ornamentals.

Other fields of application of the active ingredients according to 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 productive livestock against pests of the abovementioned type. The invention therefore also relates to pesticides such as emulsifiable concentrates, suspension concentrates, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, wettable powders, soluble powders, dispersible powders, dusts, granules or encapsulations in polymeric substances, which comprise - at least - one of the active ingredients according to the invention and which are to be selected depending on the intended aims and prevailing circumstances. The active ingredient in these compositions is employed as pure active ingredient, for example a solid active ingredient 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 surface-active compounds (surfactants). The following are possible as solvents: aromatic hydrocarbons which may be partially hydrogenated, preferably the fractions Cg to C12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalenes, 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 ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methyl-pyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, unepoxidised or epoxidised vegetable oils such as unepoxidised or epoxidised rapeseed oil, castor oil, coconut oil or soya oil, and silicone oils. Solid carriers which are generally used, for example for dusts and dispersible powders, are ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silica or 24 4 0 9 5 -22- highly-disperse absorptive polymers. Possible particulate adsorptive carriers for granules are either porous types, for example pumice, brick grit, sepiolite or bentonite, or non-sorptive carrier materials, for example calcite or sand. Moreover, a large number of pregranulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues. Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants or surfactant mixtures having good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient to be formulated. The surfactants listed below are only exemplary; a large number of other surfactants which are customarily used in the art of the formulation and suitable according to the invention are described in the specialist literature. Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 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, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The compounds mentioned generally contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenol polyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other suitable substances are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate. The cationic surfactants are mainly quaternary ammonium salts which contain at least one alkyl radical having 8 to 22 C atoms as substituents and which have lower halogenated or free alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples which may be mentioned are stearyltrimethylammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide. Suitable anionic surfactants can be either water-soluble soaps or water-soluble synthetic ?, 4 4 0 -23- surface-active compounds. Suitable soaps which may be mentioned are the alkali metal salts, alkaline earth metal salts and substituted or unsubstituted ammonium salts of higher fatty acids (Cl0-C22), such as the sodium salts or potassium salts of oleic or stearic acid or of natural mixtures of fatty acids which can be obtained, for example, from coconut oil or tallow oil; fatty acid methyltaurides may furthermore be mentioned. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. The fatty sulfonates and fatty sulfates are generally in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and generally have an alkyl radical having 8 to 22 C atoms, alkyl also embracing the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or the calcium salt of ligninsulfonic acid, of the dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric acid esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups and one fatty acid radical having 8 to 22 C atoms. Examples of alkylaryl sulfonates are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Other suitable compounds are corresponding phosphates, for example salts of the phosphoric acid ester of a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids. 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, where, as a rule, 0 to 25 %, in particular 0.1 to 20 %, of the composition can be surfactants (% is in each case to be understood as meaning per cent by weight). While concentrated compositions are more preferred as commercially available goods, the end consumer generally uses dilute compositions which have considerably lower concentrations of active ingredient. In particular, preferred compositions are composed as follows (% = per cent by weight): Emulsifiable concentrates: Active ingredient: 1 Surfactant: 1 Solvent: 5 to 90 %, preferably 5 to 20 % to 30 %, preferably 10 to 20% to 98 %, preferably 70 to 85 % 0 -24- 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: Water: Surfactant: 5 to 75 %, 94 to 24 %, 1 to 40 %, preferably 10 to 50 % preferably 88 to 30 % preferably 2 to 30 % Wettable powders: Active ingredient: Surfactant: Solid carrier: 0.5 to 90 %, 0.5 to 20 %, 5 to 99 %, preferably 1 to 80 % preferably 1 to 15 % preferably 15 to 98 % Granules: Active ingredient: Solid carrier: 0.5 to 30 %, 99.5 to 70 %, preferably 3 to 15 % preferably 97 to 85 % The activity of the compositions according to the invention can be broadened considerably and adapted to prevailing circumstances by adding other insecticidal, acaricidal and/or fungicidal active ingredients. Suitable examples of active ingredients which are added are representatives of the following classes of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions according to the invention can also comprise further solid or liquid auxiliaries, such as stabilisers, for example epoxidised or unepoxidised vegetable oils (for example epoxidised coconut oil, rapeseed oil or soya oil), defoamers, for example silicone oil, preservatives, viscosity regulators, binders and/or adhesives, and also fertilisers or other active ingredients for achieving specific effects, for example bactericides, nematicides, molluscicides or selective herbicides. The compositions according to the invention are prepared in a manner known per se, for example in the absence of auxiliaries by grinding and/or screening of a solid active ingredient, or mixture of active ingredients, for example to obtain a certain 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). 244095 -25- 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 are also part of the invention. The invention furthermore relates to the methods by which the compositions are applied, i.e. the methods for controlling pests of the abovementioned type, such as spraying, atomising, dusting, brushing on, dressing, scattering or pouring, to be selected depending on the intended aims and the prevailing circumstances, and to the use of the compositions for controlling pests of the abovementioned type. Typical application concentrations are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The application rates per hectare are generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 20 to 600 g/ha. A preferred application method in the field of crop protection is application to the foliage of the plants (foliar application), where the frequency of application and the dosage rate can be adjusted as a function of the severity of infestation with the pest in question. Alternatively, the active ingredient can reach the plants via the root system (systemic action), by allowing the locus of the plants to absorb a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example the soil, such as in the form of granules (soil application). In the case of paddy rice, such granules can be metered into the flooded paddy field. The compositions according to the invention are also suitable for protecting plant propagation material, for example seeds, such as fruits, tubers or grains, or plant cuttings, against fungal infections and animal pests. The propagation material can be treated with the composition before use, for example seed can be dressed before sowing. The active ingredients according to the invention can also be applied to seed kernels (coating) either by immersing the kernels in a liquid composition or by coating them with a solid composition. It is also possible to apply the composition to the site where the propagation material is used, for example during sowing into the seed furrow. The invention also relates to these treatment methods for plant propagation material and to the plant propagation material which has been treated in this manner. The following examples are intended to illustrate the invention. They impose no limitation on the invention. Temperatures are given in degrees centigrade. 2 4 4 0 9 5 -26- Preparation examples Example HI: 2-(4-Chlorophenyl)-3-cyano-5-pentafluoroethyl-pyirole (Table 2, Compound No. 2.1). A mixture of 47 g of 4-(4-chlorophenyl)-2,5-dihydro-5-oxo-2-pentafluoroethyl-oxazole, 131.1 g of 2-chloroacrylonitrile and 750 ml of nitromethane is refluxed for 22 hours and then cooled to approx. +5°.

The reaction mixture is stirred for 22 hours at room temperature, poured into 400 ml of water and extracted three times with diethyl ether. The organic phases are combined, washed with NaCl solution, dried over Na2S04 and evaporated in vacuo. The result is yellow crystals which are recrystallised from 10 ml of hexane. This gives the title compound which melts at 69 to 70.5°. Example H4: 2-(4-Chlorophenyl)-3-cyano-4,5-dihydro-l-methyl-5 -pentafluoroethy 1-pyrrole. cn ch3 A mixture of 15 g of N-carboxy-4-chlorophenyl-methyl-N-methyl-N-pentafluoroethyl-carbonyl-amine, 100 ml of acetonitrile, 4.2 ml of acrylonitrile, 11 g of acetic anhydride and 15 drops of triethylamine is heated under reflux for 5.5 hours and then evaporated to dryness. Purification of the residue by column chromatography [Si02; hexane/ethyl acetate (9:1)] yields the title compound, which melts at 113 to 116°. Example H5: 4-Chloro-2-(4-chlorophenyl)-3-cyano- l-methvl-5-pentafluoroethyl-pvrrole (Table 1, Compound No. 1.29). ci cn ch3 A saturated solution of 12 g of N-chlorosuccinimide in N,N-dimethylformamide is added over a period of 30 minutes to a mixture of 10 g of 2-(4-chlorophenyl)-3-cyano-4,5-dihydro-l-methyl-5-pentafluoroethyl-pyiTole and 10 ml of N,N-dimethylformamide. The reaction mixture is heated to 100° for 30 minutes and is then poured, while stirring, into 11 of water. The oily precipitate is taken up in ethyl acetate, and the ethyl acetate phase is washed several times with water, dried and evaporated to dryness. Recrystallisation of the residue using ethyl acetate/hexane yields the title compound, which melts at 120°. 24 4 0 9 5 -28- Example H6: In a manner analogous to that described in Examples HI to H5, it is possible to also prepare the other compounds listed in Tables 1 and 2.
