Abstract

Platinum nanoparticles dispersed in the ammonium salts of hyperbranched polystyrene, Pt@HPS-NR3Cl, catalyzed the hydrogenation of ketones and aldehydes when water was used as the solvent without any coexisting organic solvents. The significant increase in the reaction rate was observed when an organo-dispersible Pt@HPS-N+(C8H17)3Cl (1a) was used as the catalyst, whereas catalyst recycling was achieved with water-dispersible Pt@HPS-N+(C4H9)3Cl (1b).
