Direct Photoexcitation of Borate Enabling Minisci Reaction

Abstract The photoexcitable borate enabling Minisci C−H alkylation of heteroarene has been described. This protocol using alkylborate only needed O 2 and visible light, which provides a considerably clean system. The direct photoexcitation of alkylborate allowed the generation of tertiary , secondary , and primary ‐alkyl radical including methyl radical. This light‐driven Minisci reaction gave a choice for the functionalization of heteroarenes.
