1. A method for making a magnetic-nanoparticle-supported catalyst for hydrogen transfer and hydroformylation reactions, comprising:
reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a ferrocene unit comprising a cyclopentadienyl (Cp) ring, an alkyl substituted Cp ring, a central iron atom, one phosphine group, an amine group and at least one hydroxyl group;
wherein the Cp ring and the alkyl substituted Cp ring are bound to the central iron atom;
wherein the phosphine group is attached to the alkyl substituted Cp ring;
anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex;
combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst.
