D. Tas et al., BIFUNCTIONAL CATALYTIC MEMBRANE CONTAINING BRONSTED ACIDS AND SITES FOR ENANTIOSELECTIVE HYDROGENATION, Chemical communications, (23), 1997, pp. 2323-2324
The hydrogenation of methyl acetoacetate to give optically pure methyl
3-hydroxybutyrate is performed heterogeneously with high activity and
enantioselectivity under mild reaction conditions due to the combinat
ion of Bronsted acid and Ru-binap sites in a polydimethylsiloxane memb
rane matrix.
