Conversion of Molecular Oxygen into a Hydroperoxo Species by Ring-Opening Protonation of a Cyclic η2-Peroxo Intermediate: Characterization of the η2-Peroxo and Hydroperoxo Complexes

A transition metal–hydroperoxo species is formed by the oxygenation of a low‐valent rhodium precursor followed by a protonation of the resulting η2‐O2 ligand; the latter process is assisted by an intramolecular hydrogen‐bonding interaction (see scheme). This process is the first structural evidence...

Summary:A transition metal–hydroperoxo species is formed by the oxygenation of a low‐valent rhodium precursor followed by a protonation of the resulting η2‐O2 ligand; the latter process is assisted by an intramolecular hydrogen‐bonding interaction (see scheme). This process is the first structural evidence for an effective method for the activation of molecular oxygen as postulated for the cytochrome P‐450 system.
