A metal-free radical coupling reaction of aminophenols with amines under UV-light has been successfully developed to synthesize diaminobenzoquinone imines in high yields, in which the commercially available and cheap t-butyl hydroperoxide (TBHP) was used as an oxidant. This protocol provides an easy and green approach for the construction of benzoquinone imines with potential pharmaceutical interest avoiding metal catalyst or photocatalyst.

Key words: UV-light, radical coupling, metal-free, diaminobenzoquinone imines
