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.
