Conversion of acyclic α- and β-silyl Sulfides by their treatment with sodium salts of N-chlorosulfonamides into the corresponding previously unknown sulfimides is described. The process is accompanied by a competing reaction resulting in the formation of α- or β-silyl sulfoxides. β-Silyl sulfamide (9b) undergoes thermolysis to generate trimethylvinylsilane.

Sulfoximines 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 intermediates through triphenylphosphine, we found that the reaction was conducted through a metal-nitrene intermediate mechanism.

The N-arylsulfonyl-N'-(pyrimidin-4-yl)ureas (3a-l) were synthesized by reaction of arylsulfonyl isocyanates (1) with 4-amino-2,6-dialkylpyrimidines (2).Treatment of 3 with alkali or of 1 with an excess of 4-amino-2,6-dimethylpyrimidine (2a) gave the salts 4a-e.Reaction of the ureas 3a-c with dimethyl sulfoxide at 90 to 120 deg C afforded N,N'-bis(2,6-dimethylpyrimidin-4-yl) ureas 8a-c.The reaction is assumed to involve a four-centre mechanism with 5 as intermediate.

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.
