A facile synthesis of various allyl sulfonamides based on imidation of allyl sulfides with chloramine‐T and subsequent [2,3]‐sigmatropicrearrangement has been achieved without metal catalysts. The reaction completes smoothly within 10 min, providing excellent yields in environment friendly solvent of alcohol. Functional groups such as bromine, hydroxyl, protected amido and aldehyde are tolerant under
