Radical Arylboration of Unactivated Alkenes via Visible-Light Catalysis

A photoinduced radical arylboration of unactivated alkenes with B2pin2 and aryl nitriles was developed, providing a mild and efficient approach to access useful β-aryl boronates in the absence of a transition-metal catalyst. This reaction undergoes a boron radical addition to alkene and a subsequent radical-radical coupling process. This approach showcases good functional group compatibility and provides a promising and complementary strategy to boron chemistry and traditional transition-metal-catalyzed coupling.
