## Abstract **Two new models** for cytochrome P450 in which the thiolate axial ligand is replaced by an RSO~3~^−^ group, form oxo‐iron(IV) porphyrin π‐cation radicals as sole oxidation products in “peroxo shunt” reactions (see scheme) independent of the nature of the employed solvent (polar or non‐
## Abstract We have shown previously that iodosylbenzene–iron(III) porphyrin intermediates (2) are generated in the reactions of oxoiron(IV) porphyrin π‐cation radicals (1) and iodobenzene (PhI), that 1 and 2 are at equilibrium in the presence of PhI, and that the epoxidation of olefins by 2 afford
