Organic Sulfinic Acids and Salts in Visible Light-Induced Reactions

Sulfinic acids and their salts are a useful source of sulfur-containing structures. Photocatalysis of these compounds with visible light enables chemists to achieve various transformations under mild conditions. This review article summarizes visible light-induced reactions of sulfinic acids and their salts. This article is organized by reaction type and brief discussions on plausible reaction mechanisms for typical transformations are presented.
