Reactions of Olefins with Ruthenium Hydride Nanoparticles: NMR Characterization, Hydride Titration, and Room-Temperature C----C Bond Activation

Surface CC bond activation: Ruthenium nanoparticles prepared by hydrogenation of an organometallic precursor accommodate more than one hydride per surface ruthenium atom as well as various ligands, such as amines or phosphines, as shown by gas‐phase, liquid, and solid‐state NMR spectroscopy and tit...

Description
Summary:Surface CC bond activation: Ruthenium nanoparticles prepared by hydrogenation of an organometallic precursor accommodate more than one hydride per surface ruthenium atom as well as various ligands, such as amines or phosphines, as shown by gas‐phase, liquid, and solid‐state NMR spectroscopy and titration with olefins. These nanoparticles react with ethylene at room temperature to give ethane and surface‐bound methyl species (see scheme).
