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

Copper-catalyzedcoupling of thiols with amines was used to synthesize numerous sulfinamides in excellent yields. Sulfenamides or sulfonamides were also formed as reaction byproducts albeit in trace quantities. The procedure is carried out as a one step and was found to be promoted by the addition of water and NH4PF6 under aerobic conditions. Furthermore, the reaction proceeds smoothly when using disulfides
