The latter observation is interesting, since coupled with the results of the radical inhibition, this suggests that there are two direct oxidation mechanisms as well as the autoxidation that lead to the products of the TPP Mn-NaBH4-02 reaction a direct oxidation via a free-radical intermediate, but not through the autoxidation in which cyclohexenol formation is inhibited by 2,6-di-t-butyl-p-cresol and another direct uninhibited oxidation that leads to cyclohexene oxide.

Electrophilic addition of iodine to give intermediates such as (14) and (15) is deemed more plausible than initial homolysis of the M—M bond, particularly since addition of the radical scavenger 2,6-di-t-butyl-p-cresol has no effect on the rate of iodination.
