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
