Rodenticidal active diphenylamine, method of reducing a population of rats and mice, as well as rodenticidal composition for use in the method

摘要

Novel diphenylamines of the formula IMAGE where the substituents are defined in claim 1, are prepared. These compounds are obtained by reacting an aniline which has the substituents R1-R5 with a 2-halo-5-nitrobenzotrifluoride. The resulting compound is subsequently subjected to n-alkylation to introduce the substituent R. If necessary, halogen substituents are introduced by halogenation in the 2-, 4- and/or 6- position. The novel compounds are used as active substance in rodenticides.
