Palladium nanoparticle-cored G1-dendrimer stabilized by carbon–Pd bonds: synthesis, characterization and use as chemoselective, room temperature hydrogenation catalyst

Palladium nanoparticle-cored Fréchet type G1-dendrimer (Pd-G1) stabilized by Pd–carbon bonds is synthesized and characterized by IR, NMR, UV–Vis and TEM. Pd-G1 was found to be a highly efficient, chemoselective and reusable catalyst for the room temperature hydrogenation of carbon–carbon multiple bonds. Reducible functionalities like CHO, CO, COOR, CN, NO2 and halogens were unaffected. Pd-G1 is projected as an efficient catalyst for the selective hydrogenation of carbon-carbon multiple bonds in multifunctional organic molecules.
