Résumé
Superparamagnetic core-shell-type Fe<sub>3</sub>O<sub>4</sub>/Ru nanoparticles (particle size ca. 15 nm) synthesized by co-precipitation, adsorption and reduction methods were found to selectively hydrogenate the carbon-oxygen double bond in trans-4-phenyl-3-penten-2-one (conversion 100 %, selectivity > 90 %) with a catalytic turnover of 900 under mild reaction conditions (30 °C, 15 bar H<sub>2</sub>). The finely dispersed catalyst can be separated from the reaction mixture by using an external magnet, recycled, and reused without significant loss of activity and selectivity.
