متن کاملApplication of optically active chiral bis(imidazolium) salts as potential receptors of chiral dicarboxylate salts of biological relevance.
A family of chiral bis(imidazolium) salts derived from natural amino acids has been synthesized by a simple synthetic approach and the corresponding bis(trifluoromethylsulfonyl)imide salts have been shown to be room temperature chiral ionic liquids (RTCILs). The structures and self-assembling properties of the resulting salts have been studied by (1)HNMR, ATR-FTIR, DSC, SEM and theoretical calc...
متن کاملSynthesis and characterization of novel chiral ionic liquids and investigation of their enantiomeric recognition properties.
We report the synthesis and characterization of amino acid ester based chiral ionic liquids, derived from L- and D-alanine tert butyl ester chloride. The synthesis was accomplished via an anion metathesis reaction between commercially available L- and D-alanine tert butyl ester chloride using a variety of counterions such as lithium bis (trifluoromethane) sulfonimide, silver nitrate, silver lac...
متن کاملSynthesis and physico-chemical properties of new tetraethylammonium-based amino acid chiral ionic liquids.
This paper reports the synthesis of a series of new tetraethylammonium-based amino acid chiral ionic liquids (CILs). Their physico-chemical properties, including melting point, thermal stability, viscosity and ionic conductivity, have been comprehensively studied. The obtained results indicated that the decomposition for these salts proceeds in one step and the temperature of decomposition (T(o...
متن کاملCoordinating chiral ionic liquids.
A practical synthesis of novel coordinating chiral ionic liquids with an amino alcohol structural motif was developed starting from commercially available amino alcohols. These basic chiral ionic liquids could be successfully applied as catalysts in the asymmetric alkylation of aldehydes and gave high enantioselectivities of up to 91% ee.
