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.
