Formation of Ti(O2)(edta)2– by the addition of molecular oxygen to Ti(edta)(H2O)–; edta4–= ethylenediaminetetra-acetate
Abstract
The peroxo TiIV complex, Ti(O2)(edta)2–, is formed by the substitution of O2 on the labile TiIII complex, Ti(edta)(H2O)–, followed by two sequential one-electron reductions forming the co-ordinated peroxo ligand; the analogous reaction with H2O2 in stoicheiometric amounts produces only TiO(edta)2–; edta4–= ethylenediaminetetra-acetate.
