Participants

Reaction Steps

Methyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH3, (3.67 g; 11.6 mmol) is slowly added dropwise to dry and cooled (0° C.) N-butyl-pyrrolidine (1.38 g; 11.2 mmol) (exothermic) in a 25 ml glass flask. A pale-yellow solid forms. The reaction mixture is warmed to room temperature, diluted with 10 ml of n-hexane and stirred for 16.5 h. The readily volatile constituents are removed in vacuo (10−3 mbar) at room temperature. N-Butyl-N-methylpyrrolidinium bis(pentafluoroethyl)phosphinate, [BMPL][(C2F5)2P(O)O], (4.71 g; 10.7 mmol) is isolated as pale-yellow solid in a yield of 96% and a purity of 99%.
