    • The SHACV has been demonstrated to provide a superior approach to directly evaluating the one-electron redox potentials in the presence of a follow-up chemical reaction, relative to the better-known dc and fundamental harmonic ac methods.

    • The precise dependence expected would be a curved plot with a limiting slope of -0.5 at low driving forces and a limiting slope of -1.0 at high driving forces. The range of driving forces investigated here likely does not allow this dependence to be resolved, resulting in a linear plot with an overall slope of -0.72

    • Tolman and co-workers have demonstrated an important role of hydrogen bonding interaction between the oxygen atom of bis(μ-oxo)dicopper(III) core and a hydrogen atom being activated in the aliphatic ligand hydroxylation reaction: Mahapatra, S.; Halfen, J. A.; Wilkinson, E. C.; Pan, G.; Wang, X.; Young, V. G., Jr.; Cramer, C. J.; Que, L., Jr.; Tolman, W. B. J. Am. Chem. Soc. 1996, 118, 11555-11574. Such a hydrogen bonding interaction between the oxo group of B and phenols may also play an important role to accelerate the electron-transfer step.
