dc.description.abstractEnantioselective hydrogenation of 2,3-butanedione and 3,4-hexanedione has been studied over different type of supported Pt catalysts (Pt/Al2O3+, Pt/SiO2, Pt/MCM-4l) in the presence of cinchonidine (CD). Kinetic resultas confirmed that (i) 2,3-butanedione is more reactive than 3,4-hexanedione over all catalysts studied and (ii) both substrates have a strong poisoning effect. The kinetic results confirmed also that CD concentration close to 10-3 M is necessary to achieve both high reaction rate and enantioselectivity in the range of 55-65%. NMR results confirmed that sbstrate-modifier interaction takes also place in the liquid phase.
