Reaction Conditions:
ultrasound;
Steps:
4
4.89 g of methylimidazole (0.059 mol) and 8.98 g of butyl bromide (0.065 mol) are introduced into a beaker. The beaker is placed under ultrasound, adjusted to have a pulsation of 2 seconds, with an instantaneous power of 15 W. The butylmethylimidazolium bromide is obtained with 100% yield. This product is then added dropwise at ambient temperature to a mixture containing 50 ml of water and an equimolar quantity of lithium bis(trifluorosulphonyl)imide. The mixture is then maintained for two hours under reflux. The product is then extracted with three times 20 ml of dichloromethane before being evaporated under vacuum at 70° C. for 30 minutes. The overall yield is 94%.
