Abstract
A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; 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. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe3O4-nanoparticle-supported ferrocenyl phosphine catalyst.
Claims9
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 central iron atom, an unsubstituted cyclopentadienyl (Cp) ring, a substituted Cp ring substituted with (i) an alkyl group having an amine group and a phenyl group having at least one hydroxyl group, and (ii) one phosphine 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;
- collecting the ligand complex with a magnet;
- combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-nanoparticle-supported catalyst.
