Palladium nanoparticles-catalyzed chemoselective hydrogenations, a recyclable system in water

Chemoselective hydrogenation of double bonds in the presence of various functional groups occurred in high yields using water or toluene as solvent, and Pd nanoparticles as catalyst. Up to nine recyclings were achieved in water without decrease of the catalyst activity. (c) 2007 Elsevier Ltd. All rights reserved.
