Zusammenfassung:Benzyl esters of the formula I (I) where R1 is methyl, ethyl, halogen, methoxy or ethoxy, R2 is alkyl, alkenyl, cycloalkyl, cycloalkenyl, bicycloalkyl, bicycloalkenyl, C1-C5-alkyl-substituted cycloalkyl, C1-C5-substituted cycloalkenyl, C1-C5-alkyl-substituted bicycloalkyl or C1-C5-alkyl-substituted bicycloalkenyl, R3 is hydrogen, cyano, C2-C4-alkynyl, C2-C4-alkenyl or C1-C4-alkyl, A is the carboxylate radical of an acid component typical for pyrethroids and X is hydrogen or halogen, with the proviso that R2 is not CH2-CH=CH-B when B is hydrogen, alkyl or alkenyl and at the same time R1 is methyl or halogen, and furthermore with the proviso that R2 is not methyl when R1 is methyl, their manufacture, their use for combating pests, and precursors for manufacturing the benzyl esters.
