Abstract:
Both enantiomers of enantiopure imidazolium ionic liquids were synthesized by a simple and straightforward procedure from (R,R)- and (S,S)-2-(1H-imidazol-1-yl)cyclohexanol derivatives obtained via lipase-catalyzed resolution. Structural properties and thermal stability of these compounds have been studied to elucidate their potential applications in asymmetric catalysis.
