Abstract
The invention relates to the derivatives of cycloaliphatic acids, especially to the preparation of esters substituted cyclopropancarbonic acid of general formulaalkyl, substituted by chlorine or fluorine:A1-(YS) α-cyano-3 phenoxybenzyl; (IR) α ethinyl-3-phenoxybenzyl; (IR) α-methyl-3-phenoxybenzyl; (IR) or (IRS)-cyano-6-phenoxy-2-pyridylmethyl; α-cyano-3-phenoxybenzyl. IR and (IS)-2-methyl-4-oxo-3-(2-propinyl)-2-2cyclopenten-1-il, in addition indicated in the formula double bound can have Z or E geometry.These substances can be used as insecticides in agriculture.The purpose of the invention is creation of new more active substances of indicated class.Synthesis is led by acidic treatment of corresponding ester-acid with alcohol (introducing A group) in the organic solvent medium in the presence of alkalipyridine, dimethylaminopyridine and in the case of necessity dicyclogexylcatbodimide. The new substances are active relativ to room flys and cockroaches at the concentration of 0,031-1,273 mg/m2 against 1,95-3,1 mg/m2.
