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 proto

Sulfoximines 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 intermediates through triphenylphosphine, we found that the reaction was conducted through a metal-nitrene intermediate mechanism.

Iron-catalyzed imidative kinetic resolution of racemic sulfoxides

Kinetic resolution of racemic sulfoxides requires either custom substrates or shows moderate enantioselectivity, leading to achiral coproducts (such as sulfones) as an intrinsic part of the process. A new strategy is demonstrated that allows the resolution of racemic sulfoxides through catalytic asymmetric nitrene-transfer reactions. This approach gives rise to both optically active sulfoxides and highly enantioenriched sulfoximines. By using a chiral iron catalyst and a readily available iodinane reagent, high selectivity factors have been achieved under very practical reaction conditions. With respect to the substrate scope, it is noteworthy that this unprecedented imidative kinetic resolution of racemic sulfoxides provides access to both aryl-alkyl and dialkyl sulfoximines in highly enantioenriched forms.

(Figure Presented) Hyper-reactive: A highly reactive, fully fluorinated hypervalent iodine reagent (see formula) mediates new transformations (e.g. the one-pot conversion of sulfides to sulfoximines) and serves as a stoichiometric oxidant in well-established reactions (e.g. C-C bond cleavage and the conversion of alcohols into aldehydes).
