SUBSTITUTED 3-(1,2-DIBROMO-ALKYL)-2,2-DIMETHYL-CYCLOPROPANE-1-CARBOXYLIC ACID ESTERS, PROCESSES AND INTERMEDIATE PRODUCTS FOR THEIR PREPARATION AND THEIR USE IN AGENTS FOR COMBATING PESTS

摘要

Substituted 3-(1,2-dibromo-alkyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid esters of the formula in which R1 is halogen or optionally substituted phenyl or optionally substituted alkyl, R2 is hydrogen, halogen or optionally substituted alkyl, and Y is the radical of an alcohol customary in pyrethroids, with the proviso that Y is a benzyloxy radical which is substituted by halogen and optionally substituted by at least one additional radical if R1 is halogen or methyl, which possess pesticidal properties. The acid moieties of such esters wherein R1 is optionally substituted phenyl are new compounds.
