0.84 g (2.92 mmol) of lithium bis(trifluoromethanesulfonyl)imide in 4 ml of acetonitrile are added with stirring at room temperature to a solution of 0.5 g (2.92 mmol) of bis(dimethylamino)dichloromethane in 4 ml of acetonitrile. The mixture is stirred for 12 hours, and the solid LiCl is subsequently filtered off. Acetonitrile is distilled off. The crystals formed are dried at 50° C. under a reduced pressure of 10.0 Pa, giving 1.2 g of bis(dimethylamino)chlorocarbenium bis(trifluoromethanesulfonyl)imide, corresponding to a yield of 98.8%.
