Summary:

In this overview, an approach to synthesize calixpyrrole functionalized palladium nanoparticles employed for catalytic reaction is reported. The palladium nanoparticles (PdNPs) were synthesized using calixpyrrole tetrahydrazide system (CPTH) as a reducing as well as stabilizing agent. CPTH-PdNPs have been characterized and studied by UV-Vis, TEM (Transmission electron microscopy), EDX (Energy dispersive X-ray studies), powder XRD (Powder X ray diffraction) and dynamic light scattering (DLS) zeta potential techniques. CPTH-PdNPs are water dispersible and show excellent catalytic activity in cross-coupling Heck reactions of olefinic compounds with aryl iodides and aryl bromides giving good yields within short reaction times. A good degree of recyclability giving five consecutive catalytic tests is shown by the synthesized PdNPs.
