Quaternary Ammonium Ionic Liquids for Immobilization of Chiral Ru-BINAP Complexes in Asymmetric Hydrogenation of ?-Ketoesters
Original language description
Chiral catalytic complex (R)-[RuCl(binap)(p-cymene)]Cl was used in asymmetric hydrogenation of methyl acetoacetate to methyl-3-hydroxybutyrate in the mixed methanol-ionic liquid phase. Quaternary ammonium salts ionic liquids, namely n-alkyl-triethylammonium bis(trifluoromethane sulfonyl) imides (NR222Tf2N, R = 6, 7, 8, 10, 12, 14), were prepared and employed in this transformation. Enough evidence was provided that only a small amount of this type of IL in a conventional solvent was necessary to accommodate the catalytic complex and that the reaction could be carried out with very high enantioselectivity. Similarly it was proved that under optimized conditions the catalytic complex immobilized in this manner could be used repeatedly.
