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