文摘

Grafting of a palladium complex to the Dawson vanadotungstate polyanion [P₂W₁₅V₃O₆₂]^{9鈥?/sup> via an organic ligand generates a large family of pincer-type hybrid polyoxometalates. The palladium-POM derivatives have dual catalytic properties. Unlike their parent inorganic polyanions, they catalyze allylations while retaining their oxidant character, which leads to single-pot dual site catalysis. This opens a new route for multicatalytic reactions.}
