Abstract

New efficient rhodium catalysts supported on superparamagnetic iron oxide nanoparticles (NPs) have been prepd. using a novel method involving sulfonated triphenylphosphine ligands. They successfully promote the hydrogenation of olefins as well as the addn. of arylboronic acids to di-Me itaconate in water for up to 10 recycles. The catalysts were stable towards leaching of the metal complexes and were readily recovered by applying an external magnetic field.
