Versuchsvorschrift

0.225 g (4.41 mmol) of lithium dimethylamide are added at room temperature to 1.26 g (4.42 mmol) of bis(dimethylamino)chlorocarbenium trifluoromethanesulfonate in 20 ml of acetonitrile. The reaction mixture is stirred for 12 hours, and LiCl is subsequently filtered off. The solvent is distilled off, and the residue is washed with 20 ml of diethyl ether and subsequently dried under reduced pressure (8.0 Pa), giving 1.25 g of hexamethylguanidinium trifluoromethanesulfonate, corresponding to a yield of 96.7%.
