A series of Mn III porphyrins progressively halogenated in the electrophilic pathway of addition and a stereospecific pathway of oxygen insertion, the former being disfavoured β-pyrrolic positions was employed to catalyse the epoxidation of cis-stilbene by iodosylbenzene, and to study by electron-wi
## Binuclear manganese(III/IV) or iron(III/III) complexes efficiently functionalize cyclohexane using hydroperoxides or peracids as oxidants. A mechanistic study clearly demonstrate the role of dioxygen gas in these hydroxylation reactions. Moreover, it was demonstrated that the cleavage of the pe
