Abstract

A facial tridentate ligand is a key feature of iron catecholate complexes that elicit extradiol cleavage of catechols (see picture). The facial geometry allows O₂ and the catecholate dianion to form a tridentate intermediate on the opposite face. Accordingly, complexes of a meridional tridentate ligand do not elicit any extradiol cleavage but instead yield quinone or result in intradiol cleavage.
