Nitrile solvents containing α-CH substituents are catalytically oxidized by the tetraamido-N-FeIII-aqua complex, 3, with t-butyl hydroperoxide. Every observable product resulting from 3 has been characterized. An FeIV-cyano complex, 5, is the major inorganic product; the cyano ligand emanates from the solvent-substrate. A new type of ligand oxidative degradation giving 6 proceeds to ca. 10% of the iron macrocycle; its characterization indicates how the already robust macrocycle should be redesigned to further improve its oxidative stability. Such improvement has led to long-lived catalysts for hydrogen peroxide oxidation in water from neutral to basic pH at room temperature.
