Abstract

The first example of complete decarbonylation of a low-valent carbonyl complex to yield the corresponding high-valent oxo derivative according to (OC)_xM^zLy → (O=)_xM^z+2xLy (z = oxidation number of the metal) has been achieved by treatment of tricarbonyl(η⁵-pentamethylcyclopentadienyl)rhenium(I) (I) with hydrogen peroxide. The compound trioxo(η⁵-pentamethylcyclopentadienyl)rhemum(VII) (II) is obtained in yields up to 70% when precursor I is refluxed for 4-20 hours with hydrogen peroxide in benzene/water. By this method, the chemically very versatile trioxo species II has now become an easily available starting compound in organorhenium chemistry.
