1,4,2-Dioxazol-5-ones are five-membered heterocycles known to decarboxylate under thermal or photochemical conditions, thus yielding N-acyl nitrenes. Described herein is a light-induced ruthenium-catalyzed N-acyl nitrene transfer 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 sulfur imidation/oxidation sequence catalyzed by a single ruthenium complex is reported. Double duty: A one-pot sulfur imidation/oxidation sequence using a single ruthenium complex for both steps was developed (see scheme). Photochemical decarboxylations of 1,4,2-dioxazol-5-ones provide N-acyl nitrenes, which imidate sulfides at ambient temperature. The subsequent oxidation then occurs under mild phase-transfer catalysis conditions. In this manner, N-acyl sulfimides and sulfoximines can be obtained in high yields starting from sulfides.

In the reaction of N,N'-diphenylsulfonylselenium diimide (C6H5SO2N=)2Se with aldehydes, dimethyl sulfoxide, diphenyl selenone, diphenyl selenoxide, triphenylphosphine oxide, etc. the oxygen atom in the E=O group is substituted by a phenylsulfonylimino group.In the reaction of triphenylphosphine with N,N'-diphenylsulfonylselenium diimide N,N'-diphenylsulfonyl-N-triphenylphosphoniohydrazinate is formed.In the reaction of triphenylphosphine with N,N-diacylselenium or N,N'-diacylsulfur sulfimides (CH3CON=)2Se, (C6H5CON=)2Se or (C6H5CON=)2S triphenylphosphine oxide, the corresponding nitrile, and selenium or sulfur are obtained.
