Palladium Nanoparticles Supported on ZnO as an Efficient Catalyst for Heck Coupling Reaction

In this research, palladium nanoparticles supported on zinc oxide (ZnO) were synthesizedand characterized by various methods such as XRD, SEM and TEM. Then, palladium nanoparticles supported on zinc oxide were used as a catalyst in the Heck coupling reaction. Effects of reaction temperature, nature of used base and solvent effect on the coupling reactions were also studied. In final, a further set of experiments were carried out to check the reusability of the Pd/ZnO
for the Heck reaction. High efficiency without adding any additive makes this catalytic system as a useful and attractive method for carbon-carbon Heck coupling reaction.
