Title
Polyethylene glycol-supported recyclable NC palladacycle catalyst for Heck cross-coupling reactions
Abstract

•We have prepared new PEG supported PdNPs from NC palladacycle.•The nano-Pd preparation process is very simple and environmentally friendly.•The supported catalyst was tested in the Heck cross-coupling reaction.•PdNPs derived from PEG 15000 have very well-defined geometrical shapes.

Palladium nanoparticles with narrow size distribution were easily prepared by applying polyethylene glycol (PEG 1000 and 15000) and NC palladacycle in the absence of other chemical agents. The Pd-PEG catalysts were fully characterized by a variety of techniques including X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–vis and Fourier transform infrared (FT-IR) spectroscopy. TEM micrographs of Pd/PEG 15000 show that palladium nanoparticles have mostly very well-defined geometrical shapes. Also Pd/PEG 15000 was relatively an efficient catalyst system for the Heck reaction, affording a diverse range of products in moderate to good yields.
