Reaction Steps

Ethyl bis(nonafluorobutyl)phosphinate, (C4F9)2P(O)OC2H5, (3.834 g; 7.2 mmol) is slowly added to cooled (0° C.) N-methylimidazole (0.458 g; 5.6 mmol) in a 25 ml glass flask. An exothermic reaction and two orange phases are observed. After a few minutes, a green-coloured, more highly viscous solution forms. This is stirred at 0° C. for 2.5 h and at room temperature for 41 h. 1-Ethyl-3-methylimidazolium bis(nonafluorobutyl)phosphinate, [EMIM][(C4F9)2P(O)O], (3.233 g; 5.3 mmol) can be isolated as a highly viscous, green liquid in a yield of 95% and a purity of 95% by purification in vacuo (10−3 mbar) at room temperature to 50° C.
