A laboratory experiment aimed at students who are studying coordination chemistry of transition-metal complexes is described. A simple vanadyl acetylacetonate complex can be used as a catalyst in the hydrogen peroxide oxidation of anthracene to produce anthraquinone. The reaction can be performed under a variety of reaction conditions, ideally by different students in the same class, allowing for the accumulation of data that can be interpreted by students in their discussion of the reaction. Performed in the absence of the vanadium complex, the reaction does not produce any product. (Contains 1 table and 2 schemes.)
