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]

photochemical conditions, thus yielding N‐acyl nitrenes. Described herein is a light‐induced ruthenium‐catalyzed N‐acyl nitrenetransfer to sulfides and sulfoxides by decarboxylation of 1,4,2‐dioxazol‐5‐ones at room temperature, thus providing direct access to N‐acyl sulfimides and sulfoximines under mild reaction conditions. In addition, a one‐pot sulfurimidation/oxidation sequence catalyzed by a single

The synthesis of N-cyanosulfilimines can readily be achieved by reaction of the corresponding sulfides with cyanogen amine in the presence of a base and NBS or I-2 as halogenating agents. Oxidation followed by C-N bond cleavage affords synthetically useful NH-free sulfoximines.

N-Acyl nitrenes have been generated from a range of heterocyclic precursors, and their applications in light-inducedruthenium-catalyzedsulfurimidations have been studied. Analyzing the reaction scope and determining the structural requirements of the in situ formed electrophilic nitrogen species for effective nitrenetransfer allowed a mechanistic scheme to be proposed. The mechanistic conclusions
