Abstract

The invention relates to compounds of the general formula ##STR1## wherein R.sub.1 is hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.6 -haloalkyl or unsubstituted or mono- to penta-substituted phenyl, whereby the substituents are selected from the group comprising C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -haloalkyl, C.sub.1 -C.sub.6 -alkoxy, aryloxy, halogen, cyano and nitro, whereby if the number of substituents is greater than 1, the substituents may be identical or different; R.sub.2 is hydrogen, C.sub.1 -C.sub.6 -alkyl, (C.sub.1 -C.sub.6 -alkylene)phenyl, pyridyl, COOR.sub.6, CONR.sub.7 R.sub.8 COR.sub.6, allyl or CH.sub.2 --O--R.sub.6 ; R.sub.3 is C.sub.1 -C.sub.6 -alkyl; R.sub.4 is unsubstituted or substituted phenyl, unsubstituted or substituted benzyl or unsubstituted or substituted heterocyclyl, whereby each of the substituents, independently of each other, is selected from the group comprising C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -haloalkyl, C.sub.1 -C.sub.6 -alkoxy, aryloxy, halogen, cyano, hydroxy, amino and nitro, whereby if the number of substituents is greater than 1, the substituents may be identical or different; R.sub.6 is C.sub.1 -C.sub.6 -alkyl, phenyl or benzyl; R.sub.7 and R.sub.8 independently of one another, are hydrogen or C.sub.1 -C.sub.6 -alkyl; Q is C.sub.1 -C.sub.6 -alkylene; X.sub.1 is N or C(CN); X.sub.2 is N, C(CN), C(COOR.sub.6), C(COR.sub.6), C(SOR.sub.6), C(CONR.sub.7 R.sub.8) or C(NO.sub.2); X.sub.3 and X4, independently of each other, are O or S; and n is 0 or 1 and optionally the enantiomers thereof. The active ingredients have advantageous pesticidal properties. They are especially suitable for the control of pests on domestic animals and livestock.
