I2‐Catalyzed N‐Sulfonylation of Sulfoximines with Sulfinates in Water at Room Temperature

An oxidative coupling of NH‐sulfoximines and arylsulfinates catalyzed by of I2 and H2O2 affords N‐sulfonyl sulfoximines. The reaction proceeds under aerobic conditions in water at room temperature. The merits of this protocol include mild metal‐free reaction conditions, a green and cheap solvent, safe and simple operation, good yields, and a wide substrate scope.
