Vorschrift

10.3 grams of [BMIMCl] prepared as described above were added to a mixture of 28 mL methanol and 0.06 mL water. After complete dissolution of the [BMIMCl], 5.0 grams of dry potassium fluoride (KF) were added, and the reaction mixture was stirred at 22° C. for 20 minutes. The mixture was filtered. 4.4 grams of KF was added to the filtrate, and the mixing continued for additional 20 minutes. After filtration, the methanol was evaporated under vacuum at room temperature, and the mixture was then filtered and centrifuged. The resulting yellowish liquid was determined by elementary analysis to be the titled compound [BMIMF] in 94% yield.
