Reusable Pd-polymetallic catalysts based on magnetic ferrites for Suzuki reaction in ionic liquid

Abstract

Based on magnetic ferrites of iron (magnetite), cobalt and nickel modified with 3-aminopropyltriethoxysilane (APTES) hybrid materials Pd-Fe-Co-Ni/MFe2O4@Si-NH2@Pd (M = Fe, Co, Ni) with a protective palladium coating were synthesized. Due to the synergistic effect, new Pd-polymetallic composites exhibit high catalytic activity in the Suzuki reaction in an aqueous solution of an ionic liquid. The developed catalysts are easily removed from the reaction mixture by magnetic decantation and can be reused several times without loss of catalytic activity.
