Abstract
This study focuses on the synthesis of a novel magnetic interphase palladium catalyst immobilized on pyromellitic dianhydride (PM)-coated magnetic SnFe(2)O(4) nanoparticles. Such surface functionalization of magnetic particles represents a promising strategy to bridge the gap between heterogeneous and homogeneous catalysis methods. The structure, morphology, and physicochemical properties of these particles were thoroughly examined using various analytical techniques, including FT-IR, SEM, XRD, VSM, ICP, and EDS. The resulting SnFe(2)O(4)/SiO(2)/PM-Pd nanocatalyst exhibited excellent catalytic performance as a recyclable catalyst in Suzuki-Miyaura cross-coupling reactions at room temperature. Additionally, the catalyst demonstrated high reusability, showing minimal palladium leaching and no significant loss in activity across multiple cycles.
