Procedure
1.85 g (7.44 mmol) of bis(dimethylamino)chlorocarbenium trifluoroacetate and 0.38 g (7.45 mmol) of lithium dimethylamide are dissolved in 15 ml of acetonitrile under a protective-gas atmosphere (argon). The reaction mixture is stirred for 5 hours at room temperature, and LiCl is subsequently filtered off. The salt LiCl is washed with 5 ml of acetonitrile, and the organic phases are combined. The solvent is distilled off, and the residue is dried under reduced pressure at 7 Pa and 50° C., giving 1.81 g of hexamethylguanidinium trifluoroacetate as a viscous oil, corresponding to a yield of 99.2%.
