Abstract
Proton-coupled electron-transfer (PCET) is found in a range of oxidation-reduction reactions in biology.1 This mechanism is of interest for applications in energy conversion processes. The PCET reaction has been shown to be facilitated when the proton is transferred to an intramolecular basic site.2
Metal complex of ligands possessing both H-donor and H-acceptor sites in the second coordination sphere should be interesting candidates for proton transfer reactions induced by photooxidation of the metal ion. We have prepared new oxime-containing ligands which coordinate to metal ions such that a pyridine group is sterically restricted so it does not coordinate. Instead it can act as proximal base for accepting the oxime proton.
