Directmethylation of imidazole using methylated difunctional or tetrafunctional perfluorosulfonyl imides renders excellent yields of the corresponding room temperature ionic liquids (RTILs). This methodology provides a simple, halide-free route to several novel RTILs containing multifunctional perfluorosulfonyl imide anions.
