Mechanism of Water Splitting and Oxygen−Oxygen Bond Formation by a Mononuclear Ruthenium Complex

We report the reaction mechanism of the oxygen evolution reaction catalyzed by penta-coordinated [(CoV(TPA-αF3)(O)]3+ (TPA=tri-(2-pyridylmethyl) amine) and hexa-coordinated [(CoV(TPA-αF3)(O)OH]2+ cobalt complexes for the formation of the oxygen-oxygen bond and role...

Pentadentate Ligand

Diprotonation of a remarkably stable, toluene soluble cobalt peroxo complex supported by a neutral, dianionic pentadentate ligand leads to facile O-O bond cleavage and production of a highly reactive Co(IV) oxyl cation intermediate that dimerizes and releases O2. These processes are relevant to both O2 reduction and O2 evolution and the mechanism was probed in detail both experimentally and computationally.
