title: Organic solvent nanofiltration in asymmetric hydrogenation: enhancement of enantioselectivity and catalyst stability by ionic liquids.
abstract: This communication describes the enhancement of the enantioselectivity and the stability of Ru-BINAP with the ionic liquid trihexyl(tetradecyl)phosphonium chloride (CyPhos101), and the use of organic solvent nanofiltration for the efficient separation of the catalyst and ionic liquid from the hydrogenation product, followed by simultaneous recycling of the catalyst and ionic liquid.
