Novel, direct amination of anthraquinone by rhodium(I) complexes
Abstract
In the presence of certain rhodium(I) complexes, anthraquinone was found to react with amines to give the 1-alkylaminoanthraquinones, along with small amounts of the 1,4-bis(alkylamino)anthraquinones; this direct amination characteristically occurs only at the α-position of anthraquinone.
