Abstract

Copper(I) and copper(II) flavonolate (fla) complexes with 1,4-(di-2′-pyridyl)aminophthalazine ligand (PAPH2) have been prepared by the reaction of copper salts with flavonol and the ligand in acetonitrile or dichloromethane. The copper(II) centers are bound to the tetradentate phthalazine ligand resulting in both mononuclear and binuclear complexes. Flavonol is oxygenated to the corresponding depside catalyzed by flavonolato copper(II) phthalazine complexes.
