Abstract

3-Isoxazolylbenzyl esters of the general formulae Ia and Ib ##STR1## where R is halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.2 --C.sub.4 -alkenyl, C.sub.2 -C.sub.4 -haloalkenyl, C.sub.2 -C.sub.4 -alkynyl, C.sub.2 -C.sub.4 -haloalkynyl, unsubstituted or substituted phenylethenyl, C.sub.3 -C.sub.8 -cycloalkyl, aryl, hetaryl, CO.sub.2 R.sup.3 or CONR.sup.4 R.sup.5, PA1 R.sup.3, R.sup.4 and R.sup.5 are each hydrogen or C.sub.1 -C.sub.6 -alkyl, PA1 n is 0, 1 or 2, and the radicals R may be different when n is 2, PA1 R.sup.1 is halogen or C.sub.1 -C.sub.4 -alkyl, PA1 R.sup.2 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.2 -C.sub.4 -alkenyl, C.sub.2 -C.sub.4 -alkynyl or cyano and PA1 A is the carbonyl radical of an acid component usually found in pyrethroids, are contained in pesticides.
