Abstract
A new palladiumSchiff base complex immobilized covalently on magnetic nanoparticles PdiminoPyγFe2O3 was synthesized via the reaction of chlorofunctionalized γFe2O3 with iminopyridine followed by the reaction with palladium acetate Characterization of PdiminoPyγFe2O3 was carried out by various techniques such as XRD SEM TEM FTIR TGA ICP XPS VSM and elemental analysis PdiminoPyγFe2O3 was successfully applied as a magnetically recyclable heterogeneous catalyst in Heck and Suzuki crosscoupling reactions of various aryl halides iodide bromides and chlorides as challenging substrates with olefins and phenylboronic acid respectively The synthesized catalyst was separated easily by using an external magnet and recycled eight runs without appreciable loss of its catalytic activity and leaching of the significant quantity of Pd
