摘要

The present invention relates to new substituted biphenyloxazolines of the formula (I), process for their preparation, new intermediates and the use of the substituted bi-phenyloxazolines for combating animal pests. In formula (1), A represents hydrogen or fluoro, B represents fluoro or chloro, R represents R1 or R2, where R1 represents C1-C6-halogenoalkl having at least one fluorine atom and additionally at least one hydrogen or chlorine atom, R2 represents hydrogen, C1-C6-alkenyl, C1-C6-alkinyl, or represents C3-C6-cycloalkyl-C1-C6-alkyl which can be substituted by halogen or C1-C6-alkyl; or represents C6-cycloalkenyl-C1-C6-alkyl, or represents phenyl-C1-C6-alkyl or naphthyl-C1-C6-alkyl, each of which can be substituted by halogen, C1-C6-alkyl or nitro; or represents pyridyl-C1-C6-alkyl, which can be substituted by halogen; or represents the radical COR3, in which R3 represents C1-C6-alkyl or C1-C6-alkoxy; or represents the radical NHR5, in which R5 represents C1-C6-alkyl, or phenyl which can be substituted by halogen, X represents halogen, and m represents 0 or 1, n represents 1, with the proviso, that 2-(2,6-difluorphenyl)-4-[4-(2,2,2-trifluorethoxy)biphenyl-4]-2-oxazolin and 2-(2-chlor-6-fluorphenyl)-4-[4-(2,2,2-trifluorethoxy)biphenyl-4]-2-oxazolin are excluded.
