Enhancing Catalyst Stability for Magnetically Induced Aqueous Catalysis: Functionalization with a Hydrosoluble Zwitterionic Amidinate Ligand

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
A stable, water‐compatible catalyst for the magnetically induced hydrogenation of biomass‐derived compounds in aqueous media was developed by functionalizing magnetic core–shell FeCo@Ni nanoparticles with a new hydrosoluble zwitterionic amidinate ligand via ligand exchange in a biphasic system. The efficient conversion of biomass‐derived compounds into
