So,  we report  that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L)  using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and 15 nm. This has been characterized by 1H NMR, IR, UV, X-ray powder diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscope (SEM) analyses. These nanoparticles were used as a catalyst for coupling reaction between aryl halides with terminal alkenes, Heck reaction, in the presence of potassium carbonate (K2CO3) as a base and NMP (N-Methyl-2-pyrrolidone) as a solvent.  The present catalyst is an air and moisture stable and has significant catalytic activity in Heck cross-coupling reactions under operating conditions. Various aryl halides and terminal alkenes were coupled smoothly under air to afford the corresponding cross-coupled products in excellent yields. %U http://www.nanochemres.org/article_57522_7be8974c4a9c07911275a14e4956fae7.pdf
