S,S-Dimethyl-N-(2,4-dinitrophenyl)sulfilimine(4a) has been prepared in good yield by use of DMSO, 2,4-dinitroaniline and phosphorus pentoxide in DMF and the role of DMF in this System is discussed. The method has been applied successfully to the syntheses of several sulfilimines. The reactions of 4a with protonic compounds show an interesting ylide-exchange reaction.
