Magnetic nanoparticle supports for asymmetric catalysts

Abstract

The introduction of magnetic nanoparticles (MNPs) has favoured the recovery of catalysts with techniques of magnetic separation. Moreover, the small size of these functionalized particles becomes a well-designed way to bridge the gap between heterogeneous and homogeneous catalysis. Magnetite can be used as a support for catalytically active metals, decorated with ligands for metal complexes or with organocatalysts, which can be employed in green chemistry and pharmaceutically significant reactions. In particular, asymmetric metal complexes and enantiopure organocatalysts can lead to enantioenriched products and these reactions are summarized in this review.
