Abstract Irradiation of 1,5-dichloroanthraquinone (1,5-DCAQ) with 366-nm light in ethanol gives anthrahydroquinone (AQH2) as a final product. This is interpreted in terms of the following consecutive reactions; 1,5-DCAQ\xrightarrowhν1,5-dichloroanthrahydroquinone\xrightarrowhν1–chloroanthraquinone\xrightarrowhν1-chloroanthrahydroquinone\xrightarrowhνanthraquinone\xrightarrowhνAQH2. Similar reactions were also observed for other α-chloroanthraquinones.
