PROCESS FOR THE PRODUCTION OF AMINODIPHENYLAMINES

The present invention relates to a process for the production of aminodiphen yl- 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 forme...
