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.
