Palladium nanoparticles supported on polymer: An efficient and reusable heterogeneous catalyst for the Suzuki cross-coupling reactions and aerobic oxidation of alcohols

• Synthesis and characterization of Polymer supported Pd nanoparticles catalyst.
• Cross-coupling reaction of arylboronic acid with arylhalids by PdNPs/PS catalyst.
• Oxidation reaction of alcohols to aldehydes or ketones byPdNPs/PS catalyst.
• This catalyst is recyclable and reusable, and can be used several times.

Polymer supported palladium nanoparticle catalyst was synthesized and characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques. This catalyst exhibits good activity and stability in Suzuki cross-coupling reaction of arylboronic acid with aryl halides and oxidation reaction of alcohols to corresponding aldehydes or ketones without over oxidation. After reaction, the catalyst can be separated by simple method and used many times in repeating cycles without considerable loss in its activity.
