PROCESS FOR THE PREPARATION OF 3- (1,2-DIBROMO-ALKYL) -2,2-DIMETHYL-CYCLOPROPANE-1-CARBOXYLATES REPLACED, PESTICIDED COMPOSITES, COMBAT AND PARASITES PROCESS AND PROCESS FOR THE PREPARATION OF PESTICIDIC COMPOSITES

摘要

Substituted 3-(1,2-dibromo-alkyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid esters of the formula IMAGE 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.
