Photoinduced Palladium-Catalyzed Denitrogenative Cyclization of N -Aroyl Benzotriazoles to Phenanthridinones

Abstract
A photoinduced Pd-catalyzed denitrogenative cyclization of N-aroyl benzotriazoles was developed. Employing commercially available Pd2(dba)3/XantPhos as the catalyst and PhSiH3 as the additive, a series of N-aroyl benzotriazole derivatives was efficiently converted to phenanthridinones under mild reaction conditions.
