(Chemical Equation Presented) Addition of H+ to a synthetic (μ-1,2-peroxo)diiron(III) model complex results in protonation of a carboxylate rather than the peroxo ligand. This conclusion is based on spectroscopic evidence from UV-vis, 57Fe Mössbauer, resonance Raman, infrared, and 1H/19F NMR studies. These results suggest a similar role for protons in the dioxygen activation reactions in soluble methane monooxygenase and related carboxylate-bridged diiron enzymes.
