Recent Advances in Carbonyl‐Photoredox/Transition Metal Dual Catalysis

Abstract Organic transformations using carbonyl‐photoredox/metal dual catalysis have attracted much attention in recent years. Abundant and inexpensive carbonyl photosensitizers effectively serve as single electron, energy or hydrogen atom transfer agents to induce metal‐catalyzed cross‐coupling and dicarbofunctionalization of olefins. This review covers literature reports of metal‐catalyzed photocatalytic coupling reactions from 2020 to mid‐2023, with a focus on C−C (C(sp 3 )−C(sp 3 ), C(sp 3 )−C(sp 2 ), C(sp 2 )−C(sp 2 ), C(sp 2 )−C(sp)) and C‐heteroatom (C(sp 3 )−S, C(sp 3 )−N, C(sp 2 )−O, C(sp 2 )−S, C(sp 2 )−P, C(sp 2 )−B) bond forming reactions.
