0.5 g (2.92 mmol) of bis(dimethylamino)dichloromethane are added at room temperature to 0.86 g (3.87 mmol) of trimethylsilyl trifluoromethanesulfonate, prepared by reaction of 0.42 g of trimethylchlorosilane with 0.58 g of trifluoromethanesulfonic acid at room temperature. The reaction mixture is stirred for 5 minutes, and all volatile products are subsequently removed under reduced pressure. The residue is dried under reduced pressure at 7 Pa and 50° C., giving 0.82 g of bis(dimethylamino)chlorocarbenium trifluoromethanesulfonate, corresponding to a yield of 98.7%.
