5.88 g (19.47 mmol) of bis(pentafluoroethyl)phosphinic acid are added to 3.33 g (19.47 mmol) of bis(dimethylamino)dichloromethane. The hydrogen chloride formed is removed in a stream of nitrogen. The reaction mixture is stirred at room temperature for 30 minutes, and the residue is dried under reduced pressure at 7 Pa and an oil-bath temperature of 60° C. over the course of 3 hours, giving 8.48 g of bis(dimethylamino)chlorocarbenium bis(pentafluoroethyl)phosphinate as a liquid, corresponding to a yield of 99.7%.
