ABSTRACT:
The present invention relates to a process for the production of aminodiphenyl-amines, such as 4-aminodiphenylamine (4-ADPA), by reacting nitrohalogenated benzenes with anilines in the presence of a base as well as a copper-phosphorus complex, followed by hydrogenation of the intermediately formed nitrodiphenyl-amines.
