Iodinane- and metal-free synthesis of N-cyano sulfilimines: Novel and easy access of NH-sulfoximines
The synthesis of W-cyanosulfilimines can readily be achieved by reaction of the corresponding sulfides with cyanogen amine in the presence of a base and NBS or l2 as halogenating agents. Oxidation followed by C-N bond cleavage affords synthetically useful WH-free sulfoximines.

Rhodium-catalyzed imination of sulfoxides and sulfides: Efficient preparation of N-unsubstituted 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.
