Procedure

Methyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH3, (1.83 g; 5.8 mmol) is slowly added dropwise to dry and cooled (0° C.) triethylamine (0.59 g; 5.9 mmol) (exothermic) in a 10 ml glass flask. A yellow solid forms. The reaction mixture is diluted with 10 ml of n-hexane, warmed to room temperature and stirred for 20 min. The readily volatile constituents are removed in vacuo (10−3 mbar) at room temperature. Triethylmethylammonium bis(pentafluoroethyl)phosphinate, [CH3N(C2H5)3][(C2F5)2P(O)O], (2.19 g; 5.3 mmol) is isolated as pale-yellow solid in a yield of 91% and a purity of 99%.
