Oxidation of 4-aminophenol or benzene-1,4-diamine by bleaching powder followed by treatment of the products with hydrogen chloride was the first reported method to prepare p-quinone mono- and diimines.[‌10‌,‌11‌] Bleaching powder is a white or nearly white powder that is usually a mixture of calcium chloride hypochlorite, calcium hypochlorite, and calcium chloride, sometimes called chloride of lime. It can be prepared by reacting calcium hydroxide, or slaked lime, with chlorine gas. In this manner, N-chloroquinone imine or N,N-dichloroquinone diimines are obtained.
