Ethylenediaminetetraacetate is converted into its triacetate by peroxotitanate(IV), and strong chelation of the triacetate ligand to the metal center facilitates elimination of the pendant acetoxylate group. Various species of peroxotitanium(IV) complexes in the reaction sequence are fully characterized.
