摘要 Regioselective hydrogenation of 2,3 pentanedione was investigated over poly ( N vinyl 2 pyrrolidone) stabilized platinum nanoclusters (PVP Pt) with metal cation as modifier. The results indicated that the addition of metal cations as well as the increase of solvent polarity could enhance the regioselectivity for 3 hydroxy 2 pentanone. The use of Sn 2+ could remarkably activate the hydrogenation reaction while the use of Ce 3+ decreased the reaction activity greatly. The modification effect was explained by the toxic effect of metal cations on the metal catalyst, the polarization effect of metal cations on the carbonyl group and the steric effect of the substrate itself.
