Literature Information
Hau-To Wong, Yoong Hsiang See-Toh, Frederico Castelo Ferreira, Robert Crook, Andrew G. Livingston
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.
