In the presence of catalytic amount of I2 and H2O2, N‐sulfonyl sulfoximines were synthesized from NH‐sulfoximines and sodium alkyl‐ and aryl‐sulfinates in water under air at roomtemperature. Chirality of NH‐sulfoximines are perfectly kept in products.

and sulfilimines have attracted considerable interest among organic chemists. The Cu(II)-catalyzed imination of sulfoxides and sulfides using various N-fluoro benzenesulfonamides was investigated in this study. The scope of the reaction was demonstrated by using several substituted sulfides and sulfoxides. The flow strategy for the preparation of NH-sulfoximines was also examined. By trapping nitrene
