Organocatalytic, oxidative, intramolecular C-H bond amination and metal-free cross-amination of unactivated arenes at ambient temperature
The twinkling of an I: In a new atom-economical and environmentally friendly organocatalytic method for intramolecular C-H amination, the C-N bond forms at ambient temperature by abstraction of two atoms of hydrogen; only acetic acid and water are formed

STUDIES ON ENAMIDES PART-2 : A NOVEL PHOTOCHEMICAL SYNTHESIS OF 9H-INDOLOPHENANTHRIDIN-9-ONE, A BENZCANTHINE ANALOGUE
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.
