Oxidation of metal-bound thiolato sulfur centers in Fe(III) and Co(III) complexes with carboxamido nitrogens and thiolato sulfurs as donors: Relevance to the active sites of nitrile hydratases
H2O2 oxidation of [M-III(PyPepS)(2)](-) (M = Fe, Co) complexes with carboxamido nitrogens and thiolato sulfurs as donors affords the corresponding sulfinato [M-III(PyPepSO(2))(2)](-) species. The spectral properties of [Fe-III(PyPepSO(2))(2)](-) resemble those of the iron site of nitrile hydratase.
