Nm. Karimova et al., 1-ALKYL-2-TRIFLUOROMETHYLAZIRIDINES - THE BACISITY AND RING-OPENING REACTIONS UNDER THE ACTION OF ACIDS, Russian chemical bulletin, 46(6), 1997, pp. 1136-1139
The basicity of 1-alkyl-2-trifluoromethylaziridines is -two orders of
magnitude lower than that of non-fluorinated analogs. Aziridines are s
table to H2S and AcOH, but react with AcSH, HCl, HBr, H2SO4, TsOH, and
picric acid to give products of ring-opening.
