An efficient photocatalytic functionalization of compounds with benzylic C−H bonds by sulfoximidation in visible light is described. The mild reaction conditions allow the use of a broad array of substrates, including diarylmethane, alkyl arenes, arylacetonitrile, 2‐arylacetate, and alkynyl aryl methanes. The sulfoximidation process is highly chemoselective and leads to the corresponding sulfoximines in generally good yields. Mechanistic investigations suggested the intermediacy of sulfoximidoyl radicals.

光催化对苯甲酰CH键的磺酰亚胺化

描述了在可见光下通过亚磺酰亚胺化对具有苄基CH键的化合物进行的有效光催化功能化。温和的反应条件允许使用多种底物，包括二芳基甲烷，烷基芳烃，芳基乙腈，2-芳基乙酸酯和炔基芳基甲烷。亚磺酰亚胺化过程具有高度的化学选择性，并以通常良好的收率产生了相应的亚磺酰亚胺。机理研究表明，磺酰亚氨基自由基是中间的。
