Abstract :

Palladium-catalyzed carbon�carbon bond-forming reactions developed by Heck, Negishi and Suzuki, among others have made a critical impact on synthetic organic chemistry. In this regard, coupling reactions present wide applications in the production of polymers, agrochemicals, pharmaceutical intermediates, and high-tech materials. Palladium nanoparticles (Pd NPs) provide high activity in catalyzing Suzuki cross coupling reactions, due to their high surface to area ratio. Silica, activated carbon, carbon nanotubes and alumina are used as support materials for Pd NPs to provide heterogeneous catalysis for the reaction. Four different support materials have been used and their catalytic activities were investigated. Pd NPs were prepared by supercritical carbon dioxide deposition method and vic-dioxime derivative Palladium complexes were used as precursors. Supported Pd nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). XRD patterns showed that the size of nanoparticles changes between 2 and 10 nm.
