Procedure

20 ml of dry chloroform and 1.85 g (15.78 mmol) of N,N-dimethyltrimethylsilylamine are added to 6.23 g (14.27 mmol) of bis(dimethylamino)chlorocarbenium bis(pentafluoroethyl)phosphinate. The reaction mixture is stirred for 1 hour at room temperature, and all volatile products are removed under reduced pressure. The residue is subsequently dried at 7.0 Pa and an oil-bath temperature of 50° C. for 1 hour, giving 6.29 g of hexamethylguanidinium bis(pentafluoroethyl)phosphinate, corresponding to a yield of 99%.
