Synthesis, Characterization and Thermal Properties of a Novel Chiral Ionic Liquid with Chiral Center in Anion
An imidazolium-based chiral ionic liquid with chiral center in anion was synthesized in one step from the materials of alkylation of N-methylimidzole and (S)-(-)-2-chloro-propionic acid for the first time. The structures and thermal properties of the objective product were confirmed by FT-IR, 1HNMR and DSC, respectively. The results indicate that it may be used as a new chiral solvent for asymmetric synthesis, chiral catalyst and chiral separation.
