There are described new compounds of formula (I) wherein X is hydrogen, halogen, phenyl or C1-4alkyl; Y is fluorine or chlorine; A is -O-, -S- or -N(R1)-, wherein R1 is C1-4alkyl, phenylthio or tolylthio; n is from 1 to 12; m is from 2 to 6; R is hydrogen or one of groups (A) or (B) wherein Het is a saturated or unsaturated , 3- to 7-membered heterocyclic ring that optionally additionally comprises O or S as further hetero atom or the hetero group -N(C1-6alkyl)-; Aryl is phenyl or naphthyl; and R2, R3, R4, R5, R6, R7 and R8 are each independently of the others hydrogen, C1-4alkyl, C1-4alkoxy, C1-4alkylthio, C1-4haloalkyl, C2-6alkenyl, C2-6alkynyl, halogen, hydroxy, cyano, nitro, phenyl, amino, C1-4alkylamino, (C1-4alkyl)2amino, C1-4alkylsulfonyl or arylsulfonyl; in free form or in the form of physiologically tolerable salts. Also described are the preparation and use of such substances in the control of ectoparasites on domestic animals, productive livestock and pets, and ectoparasiticidal compositions for use on such animals. |
