2-Amino-, 1-chloro-2-amino-, and 2-amino-3-chloroanthraquinones react with halogenobenzenes in nitrobenzene in the presence of an acid-combining agent and copper catalyst to form initially 2-phenylaminoanthraquinones, which are then converted into 2-(diphenylamino)anthraquinones.In the reaction of 1-chloro-2-aminoanthraquinone with halogenobenzenes, in addition to mono- and diarylation of the amino group dehalogenation of the anthraquinone ring occurs both in the initial compound and in the arylation products, and N,N'-diphenylindanthrene is also formed.
