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.
氨基蒽醌通常用作染料和着色剂。但是已知的合成非对称取代的1,4-二氨基蒽醌的方法繁琐且复杂。通过新型单氨基-单对甲苯磺酰基蒽醌提供了一种简单高效的方法,特别适用于制备非对称取代的1,4-二氨基蒽醌。
