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
A convenient preparation of N- (arenesulfonyl) sulfoximines by oxidation of N- (arenesulfonyl) sulfilimines with sodium hypochlorite in a two phase system
N-(Arenesulfonyl) sulfilimines can be oxidized to the corresponding sulfoximes in high yields with sodium hypochlorite in an AcOEt-H2O two phase system in the presence of quaternary ammonium salts as catalysts.
