New compounds of formula (I) are described, wherein R is the group (A). R1 and R2, independently of one another, are hydrogen, halogen, cyano, nitro, C1-4-alkyl; C1-4-haloalkyl, C1-4-alkoxy, C1-4-haloalkoxy or benzyl; A is oxygen, sulphur or -N(R6)-, whereby R6 is C1-4-alkyl, phenylthio or tolylthio; p is a whole number from 1 to 10; R3, R4 and R5 independently of one another, are hydrogen, halogen, cyano, nitro, C1-4-alkyl, C1-4-haloalkyl, C1-4-alkoxy or C1-4-haloalkocy; or R3 and R4 are in neighbouring positions and, together with the phenyl ring to which they are bonded, form a naphthyl group; n is 1, 2 or 3; m is 1, 2 or 3; and Z is C1-6-alkyl, phenyl or halogen; in free form or in the form of physiologically acceptable salts. In addition, the preparation and usage of these substances in the control of ectroparasites on domestic animals, livestock or pets, is described, as well as ectoparasitic compositions for usage on these animals. |
