    • While it is possible that the weak DHA• C-H bond is the sole reason for the absence of coupled product, the scenario is unlikely given that the radical was seen by Borovik14 to escape the solvent cage and couple, even in the more viscous dimethylacetamide solvent. The likelihood of benzene solvent cage completely preventing any radical coupling is quite small

    • For X = CN, Ac the BDE values were approximated using the ABDEs reported by Bordwell: Bordwell, F. G.; Cheng, J.-P. J. Am. Chem. Soc. 1991, 113, 1736. While these BDE values are not exact, 18 cases were examined by Pedulli (reference 26a) and were shown to be highly accurate with one exception for 4-methoxytetramethylphenol, which was attributed to steric reorientation of the oxygen lone pair orbital. These approximations are therefore sufficient to establish BDE trends.
