摘要：
A novel and effective blue LED-induced methodology has been developed to synthesize a number of 6-alkyl(aryl)phenanthridines from isocyanobiaryls and alkyl(aryl)sulfinates in ethyl lactate under aerobic conditions. This protocol did not require a photoredox catalyst, and the reaction was sparked by the photochemical activity of an electron donor-acceptor complex formed by the interaction of isocyanobiaryls with alkyl(aryl)sulfinates. The environmental friendliness, mildness, gram-scale synthesizability, lack of toxic organic solvents/additives, and lack of a transition metal are only a few notable advantages of this methodology.
