Abstract
Abstract Carbazole and α-carboline are the photocyclization products of o-nitrodiphenylamine and 3-nitro-2-phenylaminopyridine respectively. The proposed mechanism includes the transfer of the amine hydrogen to the nitro group, the abstraction of HNO2 and electrophilic cyclization or cyclization to nitrohydrocarbazole followed by the elimination of HNO2. o-Aminodiarylamines do not cyclize under similar conditions.
