Photoinduced C–H direct arylation of unactivated arenes

摘要

Two general protocols have been developed for the photoinduced,metal-free direct arylation of unactivated arenes with aryl iodide.Both methods gave good to excellent yields for most substrates.Notably,the C–F bond in method A and the C–F,C–Cl,and C–Br bonds in method B could survive the arylation reaction.These methods offered excellent options for syntheses of biaryls.
