Abstract

Disclosed are compounds of formula (I) or pesticidally acceptable salts thereof, wherein, for example, W is ═N—, ═CH—, ═CR— or ═C(NRR)—, Ris halogen, Rand Rare independently of one another hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heterocyclyl, aralkyl or heterocyclylalkyl, Ris cyano, halogen, haloalkyl or CS NH, Ris alkyl or cycloalkyl, Ris hydrogen, alkyl or cycloalkyl, Ris hydrogen, alkyl or cycloalkyl, Ris haloalkyl, haloalkoxy, halogen or —SF, Ris hydrogen, halogen, haloalkyl, nitro or NRR, Rand Rare independently of one another hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heterocyclyl, aralkyl or heterocyclylalkyl, X is —S—, —SO—, or —SO—, Y is —O—, —S—, —SO—, or SO—, Z is hydrogen, halogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heterocyclyl, aralkyl, heterocyclylalkyl or NRR, and Rand Rare hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heterocyclyl, aralkyl, heterocyclylalkyl. These compounds can be used for controlling pests, especially by treatment of domestic animals.
