    • It should be noted that the autoxidations were carried out at 30 °C in chlorobenzene, whereas radical clock experiments were carried out at 37 °C in benzene. Although the higher temperatures should lead to slightly larger rate constants, because benzene is a better hydrogen bond accepting solvent than chlorobenzene, rate constants in benzene should be slightly slower. Overall, it would appear that these effects cancel each other out and the rate constants are highly comparable

    • The rate constant for 11 could not be determined by the peroxyl radical clock method because it relies on the aryloxyl radical derived from the antioxidant to carry the chain reaction. The aryloxyl radical derived from 11 is likely too reactive to oxygen to be persistent long enough to carry the chain
