Ligand-to-Copper Charge-Transfer-Enabled C-H Sulfoximination of Arenes.

Herein, we report a photoinduced sulfoximine-to-copper charge-transfer-enabled generation of sulfoximinyl radicals directly from NH -sulfoximines for C-H sulfoximination of arenes via radical addition. Through copper-LMCT, N-arylation of NH -sulfoximines was achieved for the first time using arenes of different electronic structures as the aryl donors.
