Treatment of suitably diaminated 1,4-benzoquinones (I) or monoaminated 2-hydroxy-1,4-benzoquinones (II) with sulphuric acid gives the title compounds. These exist predominantly in the o-hydroxy-p-quinone imine form rather than the p-amino-o-quinone form in chloroform solution, whereas in ethanol the tautomers are present in approximately equal amounts.
用硫酸处理适当重整的1,4-苯醌(I)或单胺化的2-羟基-1,4-苯醌(II),得到标题化合物。它们主要以邻-羟基-对苯醌亚胺的形式存在,而不是在氯仿溶液中以对-氨基-邻苯醌的形式存在,而在乙醇中,互变异构体的存在量大致相等。
