A green method for the synthesis of gelatin/pectin stabilized palladium nano-particles as efficient heterogeneous catalyst for solvent-free Mizoroki–Heck reaction

• The Mizoroki–Heck reaction catalyzed by palladium nano-particles stabilized by gelatin/pectin mixture.
• This method was the green and efficient reaction conditions.
• This method has the ability to tolerate a wide variety of substitutions.
• This reaction was the requirement lower catalytic.
• This method has the high yield.

A green method for the synthesis of gelatin/pectin stabilized palladium nano-particles has been described. These particles were prepared under green conditions without addition of any external reducing agent and ligand. All properties of the supported palladium particles on gelatin/pectin mixture were showed by UV–vis spectra and also by EDX, XRD, TEM and FESEM images. The synthesized palladium nanoparticles were studied in Mizoroki–Heck reaction between different aryl halides and n-butyl acrylate. The reaction was performed under solvent-free conditions and no complicated work up process was needed for the isolation of the nano-particles. Also the products were obtained in highly short reaction times with excellent yields.

The Pdnp/gelatin/pectin system showed a high activity toward the Mizoroki–Heck cross-coupling reaction of various aryl halides (I and Br) under solvent-free conditions.Figure optionsDownload high-quality image (70 K)Download as PowerPoint slide
