ABSTRACT:
Aminoanthraquinones are generally useful as dyes and coloring agents. But known methods of synthesizing unsymmetrically substituted 1,4-diaminoanthraquinones are tedious and complex. A simple and efficient method is provided for preparing 1,4-diaminoanthraquinones, particularly unsymmetrically substituted 1,4-diaminoanthraquinones, by means of novel monoamino-monotosyl-anthraquinones.
