Copper(I) and copper(II) flavonolate complexes have been isolated and characterized spectroscopically and structurally. Coordination of flavonol to copper through the 3-hydroxy and 4-carbonyl groups could be established by diffraction method. CuCl- and CuCl2-catalyzed oxygenation of flavonol in acetonitrile led only to a small extent to the depside or its hydrolysates. Copper(I) and copper(II) flavonolate catalyzed oxygenations gave exclusively quercetinase-like products in good yields.
