Reaction Steps

3-Bromopropyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH2—CH2CH2Br, (4.710 g; 11.1 mmol) is slowly added dropwise to cooled (0° C.) N-methylimidazole (0.907 g; 11.0 mmol) (exothermic) in a 50 ml glass flask. It The colourless, more highly viscous and slightly cloudy reaction mixture is stirred at 0° C. for 1 h and at room temperature for 3 h and purified in vacuo (10−3 mbar) at room temperature. 1-(3-Bromopropyl)-3-methylimidazolium bis(pentafluoroethyl)phosphinate, [BrCH2CH2CH2MIM][(C2F5)2P(O)O], (5.286 g; 10.5 mmol) can be isolated as colourless, highly viscous and slightly cloudy liquid in a yield of 95% and a purity of 90%.
