Abstract

Abstract: Two new palladium catalysts immobilized on modified magnetic nanoparticles containing NNN and NNS Schiff base ligands were synthesized and characterized by FT-IR spectroscopy, thermogravimetric analysis, X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, CHNS and ICP. These catalytic systems, containing Pd nanoparticles, showed high activity in the Suzuki–Miyaura cross-coupling of phenylboronic acid with aryl halides. The activity, Pd loading, reusability and Pd leaching of these catalysts were compared. The supported catalysts have the advantage to be completely recoverable with the simple application of an external magnetic field. The immobilized palladium catalysts could be reused several times without significant loss of their catalytic activities.
