Magnetic nanoparticle supported triphenylphosphine ligand for the Rh-catalyzed hydroformylation reaction

Abstract A magnetic recyclable nano-triphenylphosphine (nano-TPP) ligand was synthesized by simply loading a dopamine-triphenylphosphine derivative onto the surface of super paramagnetic iron oxide nanoparticle (SPION). Via the cooperation between surface neighbor TPP units, nano-TPPs can bond to Rh atoms forming magnetic recyclable nano-TPPRh complexes to catalyze the hydroformylation reaction and can be reused for 20 times with the compensation of Rh salt.
