In this research, we describe the structure, spectroscopy and reactivity of a family of 1st row transition metal complexes bearing bidentate redox-active ligands that contain H-bonding donor groups. Single crystal X-ray crystallography shows that these tetracoordinate complexes are stabilized by intramolecular H-bonding interactions between the two ligand scaffolds and between the ligand H-donor and the metal center. Interestingly, the Cu complexes undergo multiple reversible oxidation-reduction processes associated with the metal ion (CuI, CuII, CuIII) and/or the o-phenyldiamido ligand (L2—, L—, L).1 Moreover, these we found these different oxidation states can perform the oxidation phenolic O-H bond with different rates at low temperature.
