The reaction of 1-aminoanthraquinone with primary aliphatic amines in the presence of cobalt(II) chloride under atmospheric oxygen preferentially gave the corresponding 1-amino-4-(alkylamino)anthraquinones.The reaction did not proceed with aqueous ammonia, bidentate amines, secondary aliphatic amines, and primary arylamines.While, with alicyclic amines the reaction mainly afforded 1-amino-2,4-bis(alkylamino)anthraquinones.
