Palladium can be stabilized in the zero-oxidation state with one, two or three anionic aluminium ligands to produce mono-, di- or trianionic complexes, respectively. The palladium centres in the resulting complexes are highly negatively charged, and this electron richness enables the trianionic complex to undergo a hitherto hypothetical oxidative addition reaction with a diboron species.
