N,N'-DIACYLSELENIUM AND N,N'-DIACYLSULFUR DIIMIDES

Derkach, N. Ya.,Barashenkov, G. G.,Slyusarenko, E. I.

, p. 60 - 66 (2007/10/02)

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.
