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.

A convenient one-pot synthesis of nitro derivatives of 2,1,3-benzothiadiazole 1-oxides by the reaction of o-nitroanilines with sulfur monochloride was developed. The structural features of 4-nitrobenzothiadiazole and its N-oxide were considered. High in vitro release of nitric oxide (69%) was found for a 6-nitro-2,1,3-benzothiadiazole sample by the Griess assay, which indicated good prospects for this
