What is it about?

Grafting of a palladium complex to the Dawson vanadotungstate polyanion [P2W15V3O62]9– 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.

Why is it important?

Electronic communication between inorganic POM and organometallic Pd-complex. Recycling of palladium is possible.
