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 R<1>-R<5> 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. |
