Facile Hydrolysis and Alcoholysis of Palladium Acetate

摘要

Palladium(II) acetate is readily converted into [Pd-3((2)-OH)(OAc)(5)] (1) in the presence of water in a range of organic solvents and is also slowly converted in the solid state. Complex 1 can also be formed in nominally anhydrous solvents. Similarly, the analogous alkoxide complexes [Pd-3((2)-OR)(OAc)(5)] (3) are easily formed in solutions of palladium(II) acetate containing a range of alcohols. An examination of a representative Wacker-type oxidation shows that the Pd-OH complex 1 and a related Pd-oxo complex 4 can be excluded as potential catalytic intermediates in the absence of exogenous water.
