Acetylacetone was catalytically reduced in the course of the electrolytic reduction of bis(acetylacetonato)oxovanadium(IV) at a mercury cathode. In acetonitrile solutions the catalytic reduction proceeded at −2.1 V <I>vs.</I> Ag/0.01 mol dm<SUP>−3</SUP> AgClO<SUB>4</SUB> electrode and the reduction products were hydrogen and acetylacetonate anion, while by the direct electrolysis of acetylacetone at −2.5 V a product with vicinal hydroxyl groups was formed. A steady-state current was observed in the controlled potential electrolysis. A reaction mechanism involving the regeneration of trivalent vanadium by the coupled chemical reaction of divalent vanadium with acetylacetone is proposed.
