Reaction Conditions

Reaction Steps

Ethyl bis(pentafluoroethyl)phosphinate (1.538 g; 4.7 mmol) is added to cooled (0° C.) tributylphosphine (0.953 g; 4.7 mmol) in a 25 ml glass flask. The reaction mixture is stirred at 0° C. for 1 h, with initially a two-phase system and later the formation of a solid being observed. The reaction mixture is diluted with 10 ml of n-hexane, warmed and stirred at room temperature for 5.5 h. The readily volatile constituents are removed in vacuo (10−3 mbar) at 35° C. Tributylethylphosphonium bis(pentafluoroethyl)phosphinate, [(C4H9)3PC2H5][(C2F5)2P(O)O], (2.262 g; 4.2 mmol) is isolated as colourless solid in a yield of 89% and a purity of 98%.
