The radical versus non-radical reactive intermediates in the Iron(III) porphyrin catalyzed oxidation reactions by hydroperoxides, hydrogen peroxide and iodosylarene
In the catalytic reaction of an iron(III) porphyrin with t-BuOOH, CumOOH, H2O2 and C6F5IO, cyclohexene was used as a probe substrate. The selective hydroxylation of cyclohexene by hydroperoxides proceeds through radical path and this has been utilized for successful dioxygen activation/autooxidation. For other oxidants epoxide was the major product and the reactions proceed through non-radical path.
