We report here the improved syntheses of 1-alkyl-3-methylimidazolium ionic liquids. Microwave irradiation drastically reduces the preparation time of 1-alkyl-3-methylimidazolium and N-alkylpyridinium halide salts and, in addition, three halide-free routes to ionic liquids have been developed. New, chiral, imidazolium-based ionic liquids were prepared using both conventional and halide-free procedures. Chirality was introduced in the new compounds at either the cation or the anion, or both.
