Axial ligand substitution of a mononuclear nonheme oxoiron(IV) complex, [FeIV(O)(TMC)(NCCH3)]2+ (1) (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), leads to the formation of new FeIV=O species with relatively intense electronic absorption features in the near-UV region. The presence of these near-UV features allowed us to make the first observation of Fe=O vibrations of S = 1 mononuclear nonheme oxoiron(IV) complexes by resonance Raman spectroscopy. We have also demonstrated that the reactivity of nonheme oxoiron(IV) intermediates is markedly influenced by the axial ligands.
单核非血红素氧代铁（IV）配合物[FeIV(O)(TMC)(NCCH3)]2+（1）（TMC = 1,4,8,11-四甲基-1,4,8,11-四氮杂环十四烷）的轴向配体取代导致形成在近紫外区域具有相对较强电子吸收特征的新的FeIV=O物种。这些近紫外特征的存在使我们能够通过共振拉曼光谱首次观察到S = 1单核非血红素氧代铁（IV）配合物的Fe=O振动。我们还证明了非血红素氧代铁（IV）中间体的反应性受到轴向配体的显著影响。
