Neuartige chirale ionische Flüssigkeiten und Verfahren zu ihrer Darstellung in enantiomerenreiner oder enantiomerenangereicherter Form

摘要

The invention relates to chiral ionic liquids of the general formula [A]n<+>[Y]<n->, wherein n = 1 or 2, the anion [Y]<n-> is the anion of an organic or inorganic protonic acid and the cation [A]<+> is an optically active organic ammonium cation having up to 50 carbon atoms, at least one chirality centre and at least one functional group that can produce a co-ordination by forming hydrogen bridges or by providing free electron pairs. At least one chirality centre is provided with a distance of up to 5 atomic bonds from the functional group. The invention also relates to a method for producing said chiral ionic liquids and to the use thereof in methods for the asymmetric synthesis, the asymmetric catalysis and for separating racemates.
