Using (S)-(-)-2-chloropropionic acid ethyl ester and N-methylimidazole as raw materials, we designed and synthesized three N-methylimidazolium chiral ionic liquids by the nucleophilic substitution reaction or anion exchange reaction. These chiral ionic liquids structures were analyzed with structure optimization calculation, IR, and HNMR. Their reaction mechanism and physical chemistry properties were explored. As a result, these chiral ionic liquids possess optical activity, low melting point, high conductivity, and weak acidity, etc. They can serve as effective reaction media as well as chiral catalysts. They are presently being investigated as dispersion agent in molecular imprinting ployer in our laboratory.
