We present here a novel paired electrocatalysis-enabled convenient synthesis of the ( E )-vinyl sulfoximines through the cross-coupling reaction of sulfinamides and olefins. This protocol showed a broad substrate scope and excellent E selectivity of products under metal- and oxidant-free conditions. A preliminary mechanistic study suggested that fluorinated sulfoximine generated from anodic oxidation of sulfinamide was the key intermediate that was then converted into the sulfonimidoyl radical at the cathode with the help of DBU in this reaction.

3d-Metal catalyzed borrowing hydrogen (BH) reactions represent powerful and environmentally friendly approaches for the direct coupling of alcohols with nitriles to assemble various important branched nitriles. The development of simple and efficient ligands is a crucial issue in this field. In this study, we designed a series of readily available N , N -bidentate ligands that demonstrated good efficiency in the Mn-catalyzed BH reaction of alcohols and nitrile derivatives, yielding the targeted nitriles in moderate to good yields. Remarkably, the mildness and practicality of this protocol were further demonstrated by the successful synthesis of anipamil via a two-cascade borrowing hydrogen procedure., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)
