The synthesis of 3-aroylcarbazoles and the unknown 1-aroylcarbazoles has been achieved by the photolysis of 9-aroylcarbazoles in polar solvent.Irradiation of 3(a-c) in non-polar solvent afforded regiospecifically 5(a-c), carbazole (1) and for the first time, 9H-indolophenanthridin-9-one (8) from 3b.The yield of 8 was significantly improved by UV exposure of 9-(2-iodobenzoyl)-carbazole (3e) in methanol and iodine, without providing any photomigrated product.
