Chirality transfer in mandelate ionic liquids through ion pairing effects
摘要:
Ion pairing in [N-(3'-oxohexyl)-N-methylimidazolium][(R)-mandelate] was probed as a function of its concentration in ethanol and compared to the corresponding [(S)-camphorsulfonate] ionic liquid. The applied methodologies comprised asymmetric hydrogenation with ee monitoring as well as independent diffusion-ordered NMR and conductivity measurements. (C) 2010 Elsevier Ltd. All rights reserved.
