Direct α-C–H alkylation of alcohols via photoinduced hydrogen atom transfer

A general approach for the α-C-H alkylation of alcohols has been established, offering access to highly functionalized alcohols via visible light irradiation with TBAP as a co-catalyst. The methodology exhibits excellent functional group tolerance and a wide substrate scope. Its practicality is underscored by successful gram-scale synthesis and a sunlight-driven reaction demonstration.
