Reaction of μ-carbido-dimeric iron(IV) octapropyltetraazaporphyrinate with dicumene peroxide and tert-butyl peroxide in benzene

We report the results of our studies into the oxidation reactions of μ-carbido-dimeric iron(IV) octapropyltetraazaporphyrinate with organic peroxides. Kinetic parameters have been determined, and a possible scheme of the process suggested. The nature of peroxide has been shown to influence the rates of redox transformations. The reaction has been shown to generate the μ-carbido-dimeric iron(IV) octapropyltetraazaporphyrinate radical cation through the dissociation of the О–О bond in the peroxide coordinated to the iron atom. The reaction product enters an aggregated state over time, and readily recovers the initial form in the presence of a nitrogen-containing base.
