PHOTOCHEMICAL REACTIONS OF CHLOROANTHRAQUINONES

Article abstract of DOI:10.1246/cl.1982.1967

Irradation of 1,5-dichloroanthraquionone (1,5-DCAQ) with 366 nm light in ethanol gives anthrahydroquinone (AQH2) as a final product.This is interpreted interms of the following cosecutive reactions; 1,5-DCAQ --hν--> 1,5-dichloroanthrahydroquinone --hν--> 1-chloroanthraquinone --hν--> 1-chloroanthrahydroquinone --hν--> anthraquinone --hν--> AQH2.Similar reactions were also observed for other α-chloroanthraquinones.
