1-Methylimidazole → HCID 87309536, compound

Participants

Reaction Steps

Methyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH3, (1.870 g; 5.9 mmol) is slowly added dropwise to cooled (0° C.) N-methylimidazole (0.424 g; 5.2 mmol) (exothermic) in a 25 ml glass flask. A white solid forms. The reaction mixture is diluted with 3.5 ml of n-hexane, warmed to room temperature and stirred for 30 min. The readily volatile constituents are removed in vacuo (10−3 mbar) at room temperature. 1,3-Dimethylimidazolium bis(pentafluoroethyl)phosphinate, [MMIM][(C2F5)2P(O)O], (1.982 g; 5.0 mmol) is isolated as white solid in a yield of 96% and a purity of 97%. The isolated product is characterised by means of 1H, 19F and 31P NMR spectra in CD3CN.
