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 O<sub>2</sub>. These processes are relevant to both O<sub>2</sub> reduction and O<sub>2</sub> evolution and the mechanism was probed in detail both experimentally and computationally.

Reduction Catalysts

The amide NH group decreases the overpotential of Mn-based CO2 reduction catalysts by promoting the dimer and protonation-first pathways in the presence of H2O and enhances the CO2 electroreduction activity by facilitating C–OH bond cleavage.
