Enantioselective hydrogenation of isophorone over Pd catalysts in the presence of(-)-dihydroapovincaminic acid ethyl ester - The effect of reduction method of Pd blacks on the enantiomeric excess
The enantioselective heterogeneous catalytic hydrogenation of isophorone in the presence of apovincaminic acid ethyl ester was investigated. Various Pd black catalysts differing in their preparation method were studied. The catalysts were characterized by different methods such as physical adsorption and chemisorption, SEM and XPS. An explanation was created for the different enantioselectivity of the catalysts being precipitated by different reducing agents.
