Versuchsvorschrift
1-Methylimidazole (0.82 g, 10 mmol) was added to methylene chloride (20 ml), and (2,2,2-trifluoroethyl)(phenyl)iodonium triflate (4.54 g, 10 mmol) was added thereto while stirring in an ice bath. Thereafter, the mixture was stirred at room temperature for 3 hours. Methylene chloride was removed by distillation, and the residue was then dried using a vacuum pump while being heated. Thus, 1-methyl-3-(2′,2′,2′-trifluoroethyl)imidazolium triflate of interest was obtained in a substantially quantitative manner.
