Herein, we report a photoinduced sulfoximine-to-copper charge-transfer-enabled generation of sulfoximinyl radicals directly from -sulfoximines for C-H sulfoximination of arenes via radical addition. Through copper-LMCT, N-arylation of -sulfoximines was achieved for the first time using arenes of different electronic structures as the aryl donors.
在此，我们报告了一种光诱导亚磺酰胺-铜电荷转移引发的亚磺酰基自由基的生成，该自由基可直接从 -亚磺酰胺中生成，用于芳环的 C-H 亚磺酰化反应中的自由基加成。通过铜-LMCT，首次实现了不同电子结构芳环作为芳基供体的 -亚磺酰胺的 N-芳基化反应。
