Abstract Colloidal metal nanoparticles exhibit interesting catalytic properties for the hydrogenation of (hetero)arenes. Catalysts based on precious metals, such as Ru and Rh, promote this reaction efficiently under mild conditions. In contrast, heterogeneous catalysts earth‐abundant metals can selectively hydrogenate (hetero)arenes but require harsher Bimetallic that combine are materials to mitigate drawbacks each component. To end, RuNi bearing a phosphine ligand were prepared through decomposition [Ru(η 4 ‐C 8 H 12 )(η 6 10 )] [Ni(η ) 2 ] by at 85 °C. Wide angle X‐ray scattering confirmed bimetallic segregated structure, with Ni predominantly surface. Spectroscopic analyses revealed coordinated surface both suggesting, well, partial shell covering core. The RuNi‐based nanomaterials used in quinoline assess impact metallic composition stabilizing agent their performance.

Abstract Colloidal Ru nanoparticles (NP) display interesting catalytic properties for the hydrogenation of (hetero)arenes as they proceed efficiently in mild reaction conditions. In this work, a series based materials was used order to selectively hydrogenate quinaldine and assess impact stabilizing agent on their performances. stabilized with polyvinylpyrrolidone (PVP) 1‐adamantanecarboxylic acid (AdCOOH) allowed obtain 5,6,7,8‐tetrahydroquinaldine remarkable selectivity conditions by choosing suitable solvent. The presence carboxylate ligand surface NP led an increase activity when compared Ru/PVP catalyst. had also selectivity, modified catalysts promoted towards 1,2,3,4‐tetrahydroquinaldine, bulky displaying highest ones.
