Article abstract of DOI:10.1016/S0040-4020(01)85846-4

Pyrex-filtered sunlight irradiation of solutions of 2-amino-1,4-naphthoquinone unexpedtedly failed to produce cyclobutane dimers.Irradiation in acetic anhydride led to the formation of the trimeric 6-<3'-amino-2'-(1,4-naphthoquinonyl)>-dibenzocarbazole-5,13:7,12-diquinone as well as 3,3'-diamino-2,2'-bi-<1,4-naphthoquinonyl and dibenzocarbazole-5,13:7,12-diquinone.Similar treatment of 2-methylamino-1,4-naphthoquinone afforded 6-<3'-methylamino-2'-(1,4-naphthoquinonyl)>-dibenzocarbazole-5,13:7,12-diquinone and 6-methyl-dibenzocarbazole-5,13:7,12-diquinone
