Abstract

(Figure Presented) A combination of techniques (Mössbauer and X-ray absorption spectroscopy, H₂¹⁸O exchange experiments, and DFT calculations) has shown that the reaction of [Fe(H₂O) ₆]²⁺ with ozone generates [(H₂O) ₅Fe^IV=O]²⁺ (see calculated structure). The oxidation of selected substrates with [(H₂O)₅Fe ^IV=O]²⁺ yields unique products that are different from those generated in the Fenton reaction or derived from HO^• radicals.
