A visible light initiated α-C(sp3)–H arylation of N-(benzyloxy)phthalimides with cyanopyridines for the construction of highly valuable pyridinyl-containing diarylmethanols, including bioactive motif-based analogues, is reported. This method enables arylation of the C(sp3)–H bonds adjacent to an oxygen atom through alkoxy radical formation by O–N bond cleavage, 1,2-hydrogen atom transfer (HAT), arylation
