摘要

Thiazoline derivatives of the formula IMAGE in which Y is -N = N- or IMAGE and R¹ and R² are hydrogen or acyl with the proviso that at least one of the substituents R¹ or R² is hydrogen and Ar is a disubstituted or with another ring fused phenyl radical, with the proviso that the substituents are not in the 2,6-position, or their salts; Processes for their preparation and their use in combating ectoparasites and endoparasites.
