The explanation given above applies correspondingly to homologs and to their derived radicals.
The present invention relates to the compounds of the formula I in the form of the free base or of an acid addition salt. Acids which can be used for forming salts are inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid and phosphoric acid or organic acids such as formic acid, acetic acid, propionic acid, malonic acid, oxalic acid, fumaric acid, adipic acid, stearic acid, oleic acid, methanesulfonic acid, benzenesulfonic acid or toluenesulfonic acid.
In addition to the cis/trans isomerism of the cycloalkyl group, as mentioned, some of the compounds of the formula I have one or more asymmetric carbon atoms or stereoisomers at double bonds. It is therefore possible for enantiomers or diastereomers to occur. The invention comprises both the pure isomers and mixtures thereof. The mixtures of diastereomers can be resolved into the components by conventional methods, for example by selective crystallization from suitable solvents or by chromatography. Racemates can be resolved into the enantiomers by conventional methods, for example by forming salts with an optically active acid, separating the diastereomeric salts and liberating the pure enantiomers by means of a base.
The invention also relates to a process for the preparation of compounds of the formula 1, which comprises reacting a compound of the formula 11 ##STR6## in which A, R.sup.1, R.sup.2 and R.sup.3 are as defined under formula I and L is a leaving group, for example halogen, alkylthio, alkanesulfonyloxy or arylsulfonyloxy, alkylsulfonyl or arylsulfonyl with a nucleophile of the formula III ##STR7## in which X, E, U, n, p, R.sup.4 and R.sup.5 are as defined under formula I above, and subjecting the compounds of the formula I obtained in this way or in another way to further derivatization, if desired, on the heterocycle or in the side chain R.sup.5.
The substitution reaction described above is known in principle. The leaving group L can be varied within broad limits and can for example be a halogen atom such as fluorine, chlorine, bromine or iodine, or alkylthio such as methylthio or ethylthio, or alkanesulfonyloxy such as methane-, trifluoromethane- or ethanesulfonyloxy, or arylsulfonyloxy such as benzenesulfonyloxy or toluenesulfonyloxy, or alkylsulfonyl such as methylsulfonyl or ethylsulfonyl, or arylsulfonyl such as phenylsulfonyl or toluenesulfonyl.
The abovementioned reaction is carried out in a temperature range from 20.degree. to 150.degree. C., expediently in the presence of a base and, if desired, in an inert organic solvent such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidin-2-one, dioxane, tetrahydrofuran, 4-methyl-2-pentanone, methanol, ethanol, butanol, ethylene glycol, ethylene glycol dimethyl ether, toluene, chlorobenzene or xylene. It is also possible to use mixtures of the solvents mentioned.
Suitable bases for the case in which X is oxygen are for example alkali metal or alkaline earth metal carbonates, hydrogen carbonates, amides or hydrides, such as sodium carbonate, sodium hydrogen carbonate, potassium carbonate, sodium amide or sodium hydride, and for the case in which X is NH they are, for example, alkali metal or alkaline earth metal carbonates, hydrogen carbonates, hydroxides, amides or hydrides, such as sodium carbonate, sodium hydrogen carbonate, potassium carbonate, sodium hydroxide, sodium amide or sodium hydride, or organic bases such as triethylamine or pyridine. A second equivalent of an amine of the formula III can also be employed as auxiliary base.
When X is oxygen, the nucleophiles of the formula III required as starting materials can be prepared by known methods, for example by reducing a carbonyl group using an appropriate reducing agent, for example a complex metal hydride, or, in the case of an aldehyde or ketone, with hydrogen and a hydrogenation catalyst. For the preparation of the cis-cyclohexanols, the starting materials for the particularly preferred cis-cyclohexyloxy derivatives, particularly suitable methods are the catalytic hydrogenation of suitably substituted phenols or the reduction of suitably substituted cyclohexanone derivatives with complex hydrides which carry spatially bulky substituents, for example L-Selectride.RTM..
When X is NH, the nucleophiles of the formula III required as starting materials can be prepared by known methods, for example by reducing an oxime or a nitrile using an appropriate reducing agent, for example a complex metal hydride or hydrogen in the presence of a hydrogenation catalyst, reductive amination or Leuckart-Wallach reaction of an aldehyde or ketone or Gabriel reaction of an alkyl halide or alkyl tosylate. In order to prepare the cyclohexylamines, the starting materials for the particularly preferred cis-cyclohexylamino derivatives a particularly suitable method is the reductive amination of suitably substituted cyclohexanones with ammonium salts and sodium cyanoborohydride or with ammonia and hydrogen in the presence of metal catalysts such as nickel, ruthenium, rhodium or palladium, in which method the proportion of the desired cis amine is particularly high. A further method is the hydrogenation of anilines in the presence of hydrogenation catalysts.
Suitable reactions for the preparation of the starting materials for the particularly preferred cyclohexyl derivatives are, in particular:
1.) Alkenyl derivatives (n=5, U=direct bond, R.sup.5 =alkenyl) ##STR8##
Sg=protective group ##STR9##
Particularly suitable protective groups Sg are trialkylsilyl groups such as the trimethylsilyl or tert-butyl dimethylsilyl group. The substituents. R and R' can be varied widely (e.g. R.dbd.H, alkyl, aryl; R'.dbd.H, alkyl, aryl, heterocyclyl, alkanoyl, etc.).

The invention also relates to compositions, especially insecticidal and acaricidal compositions, which comprise the compounds of the formula I in addition to suitable formulation auxiliaries.
The compositions according to the invention generally contain the active compounds of the formula I in an amount of 1 to 95% by weight.
They can be formulated in various ways, as predetermined by the biological and/or chemicophysical parameters. The following possibilities are therefore suitable for formulation:
Wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions, sprayable solutions, dispersions on an oil or water base (SC), suspoemulsions (SE), dusting agents (DP), seed-dressing agents, granules in the form of microgranules, spray granules, coated granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.
These individual types of formulation are known in principle and are described, for example, in:
Winnacker-Kuchler, "Chemische Technologie" �Chemical technology!, Volume 7, C. Hauser Verlag, Munich, 4th Edition 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker N.Y. 2nd Ed. 1972-73; K. Martens, "Spray Drying Handbook", 3rd Ed. 1979, G. Goodwin Ltd., London.
The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives, are likewise known and are described, for example, in:
Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Darland Books, Caldwell N.J.; H. v. Olphen, "Introduction of Clay Colloid Chemistry", 2nd Ed., J. Wiley & Sons, N.Y.; Marschen, "Solvents Guide", 2nd Ed., Interscience, N.Y. 1950; McCutcheon's "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte" �Surface-active ethylene oxide adducts!, Wiss. Verlagsgesell., Stuttgart 1967; Winnacker-Kuchler, "Chemische Technologie" �Chemical technology!, Vol. 7, C. Hauser Verlag, Munich, 4th Edition, 1986.
On the basis of these formulations, it is also possible to produce combinations with other pesticidally active substances, fertilizers and/or growth regulators, for example in the form of a readymix or as a tank mix. Wettable powders are preparations, uniformly dispersible in water, which contain, besides the active compound and in addition to a diluent or inert material, wetting agents, for example polyoxethylated alkylphenols, polyoxethylated fatty alcohols, alkyl- or alkylphenolsulfonates, and dispersing agents, for example sodium ligninsulfonate or sodium 2,2'-dinaphthylmethane-6,6'-disulfonate. Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or higher-boiling aromatics or hydrocarbons, with addition of one or more emulsifiers. As emulsifiers, the following can be used, for example: calcium salts of alkylarylsulfonates, such as Ca dodecylbenzenesulfonate, or non-ionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxethylene sorbitol esters.
Dusting agents are obtained by grinding the active compound with finely divided solid substances, for example talcum, natural clays such as kaolin, bentonite, pyrophillite or diatomaceous earth. Granules can be prepared either by atomizing the active compound onto adsorptive, granulated inert material or by applying active compound concentrates onto the surface of carrier materials such as sand or kaolinites, or of granulated inert material by means of adhesives, for example polyvinyl alcohol or sodium polyacrylate, or alternatively mineral oils. Suitable active compounds can also be prepared in the fashion conventional for the preparation of fertilizer granules, if desired as a mixture with fertilizers.
In wettable powders, the concentration of active substance is for example about 10 to 90% by weight, with the remainder to 100% by weight being composed of conventional formulation components. In the case of emulsifiable concentrates, the concentration of active substance can be from about 5 to 80% by weight. Formulations in the form of dusts usually contain 5 to 20% by weight of active substance, while sprayable solutions contain about 2 to 20% by weight. In the case of granules, the content of active substance depends partly on whether the active compound is liquid or solid and on which granulation auxiliaries, fillers, etc. are used.
In addition, the active substance formulations mentioned include, if desired, the adhesives, wetting agents, dispersing agents, emulsifiers, penetrants, solvents, fillers or carriers which are conventional in each case.
For use, the concentrates--present in commercially available form--are diluted, if desired, in a customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and, in some cases, in the case of microgranules as well. Preparations in the form of dusts and granulated preparations, and sprayable solutions as well, are usually not diluted further with other inert substances before use.
The application rate required varies with the external conditions, such as temperature and humidity, inter alia. It can vary within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance; preferably, however, it is between 0.001 and 5 kg/ha.
The active compounds according to the invention may be present in their commercially available formulations, and in the application forms prepared from these formulations, in mixtures with other active compounds, such as insecticides, attractants, sterilizing agents, acaricides, nematicides, fungicides, growth regulators or herbicides.
The pesticides include, for example, phosphates, carbamates, carboxylates, formamidines, tin compounds and substances produced by microorganisms, inter alia.

The active compound content of the use forms prepared from the commercially available formulations can be from 0.00000001 to 95% by weight of active compound, preferably between 0.00001 and 1% by weight.
Application is effected in a conventional fashion, matched to the use forms.
The active compounds according to the invention are also suitable for combating ecto- and endoparasites in the area of veterinary medicine or in the area of animal keeping.
The active compounds according to the invention are applied here in a known fashion, such as by oral application in the form of, for example, tablets, capsules, potions or granules, by dermal application in the form of, for example, dipping, spraying, pouring-on and spotting-on and powdering, and also by parenteral application in the form of, for example, injection.
The novel compounds, according to the invention, of the formula I can accordingly also be employed particularly advantageously in the keeping of livestock (for example cattle, sheep, pigs and poultry such as chickens, geese, etc.). In a preferred embodiment of the invention, the novel compounds, if appropriate in suitable formulations (cf. above) and if appropriate with the drinking water or feed, are administered orally to the animals; Since excretion in the droppings occurs in an effective fashion, the development of insects in the animal droppings can be prevented very simply in this fashion. The dosages and formulations suitable in each case are particularly dependent on the type and stage of development of the productive animals and also on the degree of infestation of the insects, and can easily be determined and fixed by conventional methods. In the case of cattle, the novel compounds can be employed, for example, in dosages of 0.01 to 1 mg/kg of body weight.
The compounds of the formula I according to the invention are also distinguished by an outstanding fungicidal action. Fungal pathogens which have already penetrated the plant tissue can successfully be controlled curatively. This is particularly important and advantageous in the case of those fungal diseases which can no longer be controlled effectively with the otherwise conventional fungicides once infection has taken place. The spectrum of action of the claimed compounds embraces a variety of economically important phytopathogenic fungi such as, for example, Plasmopara viticola, Phytophthora infestans, Erysiphe graminis, Piricularia oryzae, Pyrenophora teres, Leptosphaerea nodorum and Pellicularia sasakii and Puccinia recondita.
In addition, the compounds according to the invention are also suitable for use in industrial areas, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metalworking, or as a preservative in drilling and cutting oils.
The active substances according to the invention can be employed in their commercially available formulations, either alone or in combination with other fungicides known from the literature.

The abovementioned co-components are known active compounds, many of which are described in Ch. R. Worthing, S. B. Walker, The Pesticide Manual, 7th Edition (1983), British Crop Protection Council. The active substance content of the use forms prepared from the commercially available formulations can be varied within wide limits; the concentration of active compound in the use forms can be from 0.0001 to 95% by weight of active compound and is preferably between 0.0001 and 1% by weight.
