Recent Advances in Carbonyl‐Photoredox/Transition Metal Dual Catalysis

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.
