[reaction: see text] Silver salts in the presence of a chelating ligand efficiently catalyze the stereospecific imination of sulfoxides and sulfides with sulfonylamides and PhI(OAc)(2) to afford sulfoximines and sulfilimines, respectively, in good yields.

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

[reaction: see text] The Fe(III)-catalyzed imination of sulfoxides and sulfides with sulfonylamides in the presence of iodinanes has been investigated. The best results were obtained when Fe(acac)(3) was used as a catalyst in combination with iodosylbenzene, providing an effective alternative (stereospecific) access to sulfoximines and sulfilimines.

The Rh(II)-catalyzed imination of sulfoxides and sulfides using [Rh(2)(OAc)(4)] as a catalyst and trifluoroacetamide or sulfonylamides in combination with iodobenzene diacetate and magnesium oxide affords sulfoximines and sulfilimines, respectively, in a stereospecific manner. [reaction: see text]
A new practical procedure of imination for sulfide has been developed. The treatment of (N-tosylimino)-phenyl-λ3-iodane, PhINTs, with various sulfides in the presence of a catalytic amount of I2 under metal-free conditions affords the corresponding N-tosylsulfilimine compounds with moderate to good yields. This facile transfer procedure of the sulfonylimino group can also be applied to triphenylphosphine
