Palladium nanoparticles in poly(ethyleneglycol): the efficient and recyclable catalyst for Heck reaction

Palladium nanoparticles were prepared by applying poly(ethyleneglycol) (PEG) and Pd(OAc)2 in the absence of other chemical agents. The as-prepared palladium nanoparticles were found to be a highly stable and reusable catalyst for Heck reaction.
