For example, the nitrile derivative R3CH2CN is condensed with the ketone or the aldehyde R7COR6 in the presence of a base to provide the acrylonitriles XIII. Preferably R3 in R3CH2CN is an aryl or heteroaryl group as defined above for R3. Typically, a nitrile is dissolved in a solvent, for example, ethanol and water to which the aldehyde or acetone is added followed by a base. Typical bases used may be hydroxides, alkali metals, for example, neighborhood, potassium or sodium and the mixture is typically stirred at room temperature.
The acrylonitrile XIII is treated as described in Scheme D with sulfur ylide to provide the cyclopropyl nitriles XIV.

The compositions and compounds of the present invention can be applied directly to the site to be protected, for example, the area around or on the economic plants infected with insects or the plants on which infection is to be prevented. Examples of harmful insects belong to the orders Lepidoptera, Coleóptera, - Diptera, Thysanoptera, Hymenoptera, Heteroptera, Homoptera, Orthopera, and Acariña. The compounds and compositions can be applied as contact or systemic pesticides. The compounds of the invention are applied to the habitat of the insect at a rate of 0.0005 to 10 kilograms per hectare, preferably 0.05 to 5 and more preferably 0.1 to 1 kilograms per hectare. In the practice of the method of the invention, the active compound can be applied to the soil or foliage where it is absorbed by the plant, transmitted to other parts of the plant and, in the long run, ingested by the pest or insects by ingestion of the part or parts of the plant. This means of application is called systemic application. Alternatively, the active compound can be applied to the soil and contacted there with the insects and other pests that it is desired to control. This means of application is called soil application. Another possibility is that the active compound can be applied to the foliage of plants that will be released from insects and other pests that feed on the foliage. The compositions and formulations according to the present invention may also include known pesticidal compounds. This broadens the spectrum of activity of the preparation and can give rise to synergism. Among the suitable insecticides known in the art are those listed in the United States Patent 5, 075,471, see in particular columns 14 and 15. The compounds of the present invention can be applied in the form of compositions or formulations. An example of the preparation of compositions and formulations can be found in the publication of the American Chemical Society "Pesticidal Formulation Research" (1969), Series of Advances in Chemistry No. 86, written by Wade Van Valkenburg and in the publication of Marcel Dekker, Inc . "Pesticide Formulations", (1973) edited by Wade Van Valkenburg. In these compositions and formulations, the active substance is mixed with the conventional inert element acceptable from the agronomic point of view (that is, compatible with the plant or inhented from the point of view of the pesticide, or both), diluents or extenders of plagiarids, for example solid transported material or liquid transported material, of the type usable in conventional compositions or formulations of plagicides. By "agronomically acceptable carriers" is meant any substance that can be applied to dissolve, disperse or diffuse the active ingredient in the composition without hindering the effectiveness of the active ingredient and which alone has no significant harmful effect on the soil. , equipment, desirable plants or agronomic environment. If desired, adjuvants can also be combined, for example, sulfactants, stabilizers, antifoaming agents and anti-aging agents. Examples of compositions and formulations according to the invention are aqueous solutions and dispersions, oily solutions and oil dispersions, pastes, dusting powders, wettable powders, emulsifiable concentrates, flowable elements, granules, baits, invert emulsions, aerosol compositions and Fumigating candles. Moisturizing powders, pastes, flowable elements, emulsifiable concentrates are concentrated preparations that are diluted with water before or during their use. In such formulations, the compounds are expanded with a liquid or solid carrier and, when desired, suitable surfactants are incorporated. Decoys are preparations that generally comprise a food or other substance attractive to insects, which includes at least one compound of the instant invention. Generally, it is desirable, particularly in the case of foliar spray formulations, to include adjuvants, for example, wetting agents, spreading agents, dispersing agents, tackifiers, adhesives and similar agents in accordance with a list of the adjuvants commonly used in the art. The technique, and an analysis thereof, can be found in many references, for example in the publication of John W. McCutcheon, "Detergents and Emulsifiers, Annual". The active compounds of the present invention can only be used as mixtures with one another or with solid or liquid dispersible carrier vehicles or other compatible active agents, especially plant protection agents, for example insecticides, arthropodicides, nematicides , fungicides, bactericides, rodenticides, herbicides, fertilizers, growth regulating agents and cinergists. In the composition of the invention, the active compound is present in an amount substantially between about 0.0001 (1: 999,999) -99 (99: 1)% by weight. For compositions suitable for storage or transportation, the amount of the active ingredient is preferably between about 0.5 (1: 199) -90 (9: 1)% by weight, and more preferably between about (1:99) -75 ( 3: 1)% weight of the mixture. Suitable compositions for direct filtration or field application generally contain the active compound in an amount substantially between 0.0001 (1: 999,999) -95 (19: 1)%, and more preferably between about 0.0005 (1: 199,999) -75 (3: 1)% by weight of the mixture. The composition can also be designated as a proportion of the compound with respect to the carrier. In the present invention, the proportion by weight of these materials (active compound / carrier) can vary from 99: 1 (99%) to 1: 4 (20%) and more preferably from 10: 1 (91%) to 1: 3 (25%). In general, the compounds of the present invention can be dissolved in certain solvents, for example, acetone, methanol, ethanol, dimethylformamide, pyridine or dimethylsulfoxide and the solutions can be diluted with water. The concentrations of the solution may vary from about 1% to about 90% with a preferred range of about 5% to about 50%. For the preparation of emulsifiable concentrates, the composition can be dissolved in suitable organic solvents, or a mixture of solvents, together with an emulsifying agent to improve the dispersion of the compound in water, the concentration of the active ingredient in the emulsifiable concentrates is generally about 10. % to about 90%, and in fluid emulsion concentrates it can be up to about 75%. Wettable powders suitable for sprinkling, can be prepared by mixing the compound with a finely divided solid, such as clay, inorganic silicate and carbonate, and silica and incorporating wetting agents, sticking agents or dispersing agents in mixtures. The concentration of the active ingredients of the formulations is generally in the range of from about 20% to about 99%, preferably from about 40% to about 75%. A typical wetting powder is made by mixing 50 parts of a compound of Formula I, 45 parts of a silicon dioxide, and 5 parts of sodium lingosulfonate. In another preparation a kaolin clay (Barden) is used in place of synthetic precipitated hydrated silicone dioxide in the above wetting powder, and in another preparation 25% is replaced with a synthetic sodium silicoaluminate. The powders are prepared with the compounds of Formula I, or the enantiomorphs, salts and complexes thereof having finely divided inert solids which may be organic or inorganic in nature. Useful materials for this purpose include botanical flours, silicas, silicates, carbonates and clays. A convenient method for preparing a powder is to dilute a wetting powder with a finely divided carrier. Powder concentrates containing from about 20% to about 80% active ingredient are commonly manufactured and are subsequently diluted from about 1% to about 10% to be used in the concentration. The active compounds can be applied as sprays and insecticides by commonly used methods, for example high gallonage hydraulic sprays, low gallonage sprays, ultra low volume sprays, air blast sprays, aerial sprays and powders. The present invention also contemplates methods for killing, combating or controlling pests comprising contacting the pests with a combative or toxic amount. (that is, an amount effective from a pesticidal point of view) of at least one active compound of the invention alone or together with a transported vehicle (composition or formulation) as noted above. The term "contacting" as used in the present specification and the claims means applying at least one of (a) said pests and (b) the corresponding habitat thereof (ie, the place to be protected, by example, a crop being grown or an area where a crop will be grown) the active compound of the present invention alone or as a constituent of a composition or formulation. In addition to the aforementioned ingredients, the preparations according to the invention may also include other substances commonly used in preparations of this type. For example, a lubricant, for example calcium stearate or magnesium stearate, can be added to the wetting powder or to a mixture to be granulated. In addition, for example, "adhesives" may be added, for example, polyvinyl alcohol-based cellulose derivatives or other colloidal materials, for example caffeine to improve the adhesion of the plasmicide to the surface to be protected.
