Carboxylate-enhanced reactivity in the oxygenation of copper flavonolate complexes
The oxygenolytic cleavage of flavonolate coordinated to copper(II) with the auxiliary ligand 3,3'-iminobis(N,N-dimethyl-propylamine), [Cu-II(fla)(idpa)]ClO4, is enhanced by the addition of acetate and benzoate. Monodentate coordination of the flavonolate forced by the carboxylate ligands is believed to be the reason for the higher reaction rates. (C) 2003 Elsevier B.V. All rights reserved.
