Paired Electrocatalysis-Enabled\nCross Coupling of\nSulfinamides with Olefins toward the Synthesis of Vinyl Sulfoximines

We present here a novel paired electrocatalysis-enabled\nconvenient\nsynthesis of the (<i>E</i>)-vinyl sulfoximines through the\ncross-coupling reaction of sulfinamides and olefins. This protocol\nshowed a broad substrate scope and excellent <i>E</i> selectivity\nof products under metal- and oxidant-free conditions. A preliminary\nmechanistic study suggested that fluorinated sulfoximine generated\nfrom anodic oxidation of sulfinamide was the key intermediate that\nwas then converted into the sulfonimidoyl radical at the cathode with\nthe help of DBU in this reaction.
