Direct Photoexcitation of Borate Enabling Minisci Reaction

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.
