Synthesis and Characterization of Novel Ester Functionalized Chiral Ionic Liquids
Three different chiral ionic liquids, chloride (R)-(+)-β-(1-methyl-imidazole)–propio-nate, (R)-(+)-β-(1-methyl-imidazole)-propionate terafluoroborate and hexafluorophosphate, weresuccessfully synthesized via the nucleophilic substitution reaction and the anion metathesis reaction, with (S)-(-)-2-chloro-propionic acid as the chiral source. Structures of the chiral io-nic liquids have been characterized by the infrared spectroscopy, nuclear magnetic resonancespectroscopy and quantum chemical structure optimization method. These new ionic materia-ls can be used as building blocks for the synthesis of ionic liquids.
