Palladium diiodide (Cat No.:L043886) is an inorganic compound composed of palladium in the +2 oxidation state coordinated with two iodide ions. It appears as a dark brown to black crystalline solid and is sparingly soluble in water but soluble in coordinating solvents like acetonitrile. PdI₂ is primarily used as a catalyst or catalyst precursor in organic synthesis, including cross-coupling reactions, carbon–carbon bond formation, and hydrogenation processes. Its reactivity is influenced by the soft, polarizable iodide ligands, which enhance its activity and selectivity in transition-metal-catalyzed transformations in pharmaceuticals and fine chemicals.
