摘要
Fe-II(TMC)(OTf)(2) reacts with 2-(BuSO2)-Bu-t-C6H4IO to afford an oxoiron(IV) product, 2, distinct from the previously reported [Fe-IV(O-anti) (TMC) (NCMe)](2+). In MeCN, 2 has a blue-shifted near-IR band, a higher nu(Fe=O), a larger Mossbauer quadrupole splitting, and quite a distinct H-1 NMR spectrum. Structural analysis of crystals grown from CH2Cl2 reveals a complex with the formulation of [Fe-IV(O)(TMC)(OTf)](OTf) and the shortest Fe-IV=O bond 1.625(4) angstrom] found to date.
