Abstract

IN RECENT YEARS, PALLADIUM CATALYZED C-C BOUND FORMATION HAS BEEN EVOLVED INTO A GENERAL TECHNIQUE FOR COUPLING DIFFERENT SUBSTRATES UNDER VARIOUS CONDITIONS. ON THE OTHER HAND, CYCLOPALLADATED COMPLEXES AS AN IMPORTANT MATERIAL IN INORGANIC CHEMISTRY PLAY IMPORTANT ROLE IN DIVERSE FIELDS OF STUDY ESPECIALLY IN COUPLING REACTIONS [1, 2]. HOMOGENEOUS PALLADIUM NANO CATALYST HAVE HIGHER REACTION RATE THAN HETEROGENEOUS BUT THERE ARE SOME PROBLEMS CONCERNING WITH THESE CATALYST SUCH AS NEED OF HIGH PRICE LIGANDS, SEPARATION FROM REACTION MIXTURE AND REUSE OF EXPENSIVE METAL CATALYST.IN THIS STUDY A PVP-SUPPORTED PALLADIUM NANO-CATALYST IS PREPARED AND CHARACTERIZED BY SCANNING ELECTRON MICROSCOPY (SEM), TRANSITION ELECTRON MICROSCOPY (TEM) AND X-RAY DIFFRACTION (XRD) TECHNIQUES. PALLADIUM NANOPARTICLES SUPPORTED ON PVP WAS USED AS AN EFFICIENT CATALYST IN THE SUZUKI CROSS-COUPLING REACTIONS OF PHENYL BRONIC ACID WITH ARYL HALIDES (SCHEME 1). OPTIMUM CONDITION FOR SUZUKI REACTION WAS EVALUATED BY VARIOUS TEMPERATURES, DURATION OF REACTION, AND KIND OF BASE, SOLVENT AND AMOUNT OF CATALYST. ALL REACTIONS WERE MONITORED BY GC AND GENERALLY GAVE HIGH YIELD OF COUPLED PRODUCTS.
