In this study, a cyclopalladated complex [Pd(ppy)(phen-dione)]PF6, was prepared by the reaction between [Pd(ppy)(µ-Cl)]2,(ppy=2-phenylpyridinate) and 1,10-Phenanthroline-5,6-dione (Phen-dione) ligand. Then, this complex was characterized by 1H NMR, 13C NMR, FT-IR,and UV-vis spectroscopies and elemental analysis. Among the useful features of this complex are its thermally stable and not sensitive to air and humidity. The catalytic activity of the cyclopalladated compound was evaluated in catalytic activity in the Heck reaction of a variety of aryl halides with n-butylacrylate and the Suzuki–Miyaura cross-coupling reaction of aryl bromides with phenylboronic acid in bulk solution. The effect of solvent, base and catalyst loading on the coupling reactions is also described. The resulting coupled products were obtained in short reaction times, with low catalyst loads and in good to excellent yields.
