Rates of exchange : Evidence that nonheme oxoiron( IV ) complexes exchange their oxygen atoms with H 2 18 O was obtained for the first time, by monitoring electrospray ionization mass spectral changes of the oxoiron( IV ) species. The oxygen‐atom exchange depended markedly on the amounts of H 2 18 O present and reaction temperatures but not on the presence of trans axial ligand (see scheme).
