In this project, we have developed a novel, efficient and mild condition for amide bond construction from phenyl acetylene/styrene/allyl benzene and isocyanide in the presence of TBHP/TBAI as an oxidant under light condition. This protocol might be an alternative procedure for the amidation under the metal free via radical pathway from isocyanide with step down reaction. The notable features of this protocol are carbon deletion, broad substrate scope, mild condition, visible light, and metal free. Moreover, this is a new tactics for the synthesis of amide bond from Alkyne/Alkene/Allyl group with Isocyanides via carbon deletion strategy in the presence of visible light.
