    • Since the specifics of these reactions are unknown from a theoretical standpoint (i.e., we do not know if the electron and proton are going to the same (a hydrogen atom transfer (HAT)) or different (a concerted PCET) acceptor orbitals), we prefer to use Cukier's more general nomenclature (ref 34) for thermodynamically coupled proton/electron-transfer reactions. Here, "ETPT" means that the ET and PT occur in one kinetically irresolvable step, while "ET/PT" designates that the ET and PT processes can be broken down into two kinetically resolvable steps, with the ET event occurring prior to proton transfer (PT).

    • Due to the low yields and low molecular weights of products in diethyl ether oxidations, we were only able to confirm that an aldehyde was produced. This suggests an oxidative O-dealkylation through a rebound-like process.

    • Attempts were made to obtain a pure standard of PMA. These attempts all yielded impure material which quickly decomposed into a brown polymeric substance, presumably due to inter- and intramolecular iminium formation between the aldehyde and methylamine moiety.

    • No change in product distributions is noted if the reaction temperature is increased to -60°C, which is the highest temperature at which these complexes will cleanly oxidize substrates.

    • The phenolate oxidations reported by Itoh were carried out in acetone. This solvent may compete somewhat with phenolate coordination, which could suppress phenolate binding constants in this system.
