Abstract
New chiral room temperature molten salts (ionic liquids) based on the pinene-pyridinium unit associated with triflate or trifluoroacetate anions were prepared. The thermal behavior of these salts was observed by DSC and solventless 1H NMR spectrum, whereas the diastereomeric interactions were studied by test asymmetric reactions, GC, CD spectroscopy, and 19F NMR spectra. X-Ray structure of iodide intermediate is presented.
