(β-Trifluoromethyl)vinyl sulfoniumsalt as a novel three-carbon fluorinated building block was conveniently prepared from easily available (β-trifluoromethyl)vinyl sulfide and diphenyl iodonium salt in excellent yield. This easily handled crystalline reagent displayed two types of useful transformation involving aziridination and vinylation to afford the corresponding trifluoromethylated compounds in excellent

An efficient and straightforward approach towards the synthesis of 1-alkyl-2-(trifluoromethyl)aziridines starting from 1,1,1-trifluoroacetoneviaimination, α-chlorination, hydridereduction and ring closure was developed. In addition, novel primary β-iodo amines were obtained by regioselective ring opening of these 2-(trifluoromethyl)aziridines using alkyl iodides, and their synthetic potential was

The basicity of 1-alkyl-2-trifluoromethylaziridines is -two orders of magnitude lower than that of non-fluorinated analogs. Aziridines are stable to H2S and AcOH, but react with AcSH, HCl, HBr, H2SO4, TsOH, and picric acid to give products of ring-opening.
