We present an efficient and versatile visible light-driven methodology for synthesizing sulfinamides and sulfoxides using nitroarenes as the nitrogen source and thiophenols as the sulfur source. The switch-over of the two reaction pathways was achieved by changing the type of photocatalyst and the amount of thiophenol in the reaction mixture. The reaction proceeds under mild conditions with good functional

sulfinamides are prepared by copper‐catalyzed transsulfinamidation of primary sulfinamides with O‐benzoyl hydroxylamines. Subsequent oxidations of the resulting products lead to the corresponding sulfonamides. Treatment of N‐aryl sulfinamides with O‐benzoyl hydroxylamines under copper catalysis provides N‐aryl sulfonimidamides.

Achieving the preparation of enantiomerically enriched -stereogenic compounds is a long-standing objective in stereoselectivesynthesis, owing to the fundamental importance and broad applications of these chiral scaffolds in various fields. Despite recent significant advancements, catalyst-controlled stereoselectivesynthesis of -stereogenic compounds remains to be a considerable challenge, particularly
