Secondary or tertiary 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.
