Sulfimides special

Special cases of this reaction are the syntheses of TP betaines (53, see below) from pyrimidin-2-ylcarbamoyl chlorides and trimethylsilyl azide [89JCS(P1)1727] and of TP-1-oxides (31, see below) form pyrimidin-2-yl sulfimides and nitrile oxides [76JCS(P1)2166]. 

A special oxidizing agent. A.A-dichlorotrifluorornethanesulfonamide, converts aryl trifluoro-methyl sulfides into sulfimides at room temperatures (Table 19).296 Bis(perfluorophenyl) sulfide is converted into the sulfone 12 by refluxing for an extended period with in situ prepared peracetic acid.297...
