transsulfinamidation of primary sulfinamides with alkyl, aryl, and heterocyclicamines for the synthesis of diverse secondary and tertiary sulfinamides has been realized. Unlike transition metal-catalyzed cross-coupling approaches restricted to non-commercially available disubstituted O-benzoyl hydroxylamines, this newly developed protocol is suitable for diverse readily available primary and secondary amines without
develop a simple and convenient method for the Ni/NHC-catalyzed cross-coupling of methyl sulfinates and amines without an acid/base to afford secondary or tertiary sulfinamides in moderate to good yields. The method can provide the desired products with broad substrate scope, good chemoselectivity and good functional group compatibility. The presented approach may enrich the Ni/NHC catalyst system and

We have developed a simple and convenient method for the cross‐coupling of arylboronicacids and their derivatives with DAST‐type reagents under mild and metal‐freeconditions to directly afford sulfinamides in moderate to good yields. Moreover, sulfonamides were obtained after a simple oxidation reaction. The reaction mechanism was investigated by 18O‐labeling experiments, and the synthetic utility

sulfinamides are prepared by copper‐catalyzed transsulfinamidation of primary sulfinamides with O‐benzoyl hydroxylamines. Subsequent oxidations of the resulting products lead to the corresponding sulfonamides. Treatment of N‐aryl sulfinamides with O‐benzoyl hydroxylamines under copper catalysis provides N‐aryl sulfonimidamides.
