Published: October 2021

The iron oxo unit, [Fe=O] is a critical intermediate in biological oxidation reactions. While its higher oxidation states are well studied, relatively little is known about the least-oxidized form [Fe=O]. Here, the thermally stable complex PhB(AdIm)Fe=O has been structurally, spectroscopically, and computationally characterized as a iron(III) oxo. An unusually short Fe-O bond length is consistent with iron-oxygen multiple bond character and is supported by electronic structure calculations. The complex is thermally stable yet is able to perform hydrocarbon oxidations, facilitating both C-O bond formation and dehydrogenation reactions.

The nonheme iron(II) complexes containing a fluoride anion, Fe(BNPAO)(F) () and [Fe(BNPAOH)(F)(THF)](BF) (), were synthesized and structurally characterized. Addition of dioxygen to either or led to the formation of a fluoride-bridged, dinuclear iron(III) complex [Fe(BNPAO)(F)(μ-F)] (), which was characterized by single-crystal X-ray diffraction, H NMR, and elemental analysis. An iron(II)(iodide) complex, Fe(BNPAO)(I) (), was prepared and reacted with O to give the mononuclear complex -Fe(BNPAO)(OH)(I) ().

Article Synopsis
  • - A new crystalline compound has been discovered, consisting of a ferric acetate unit and formed from hydrated iron(III) nitrate and acetic anhydride, with the chemical notation [Fe(CHO)O(CHO)].
  • - The structure features individual [FeO(OAc)] units linked by bridging acetate ions to create zigzag chains, with unique coordination of a carbonyl group from acetic acid at one of the iron centers.
  • - This is the first time an acetic acid molecule has been reported coordinating with an iron ion, showing a weaker bond that contrasts with a similar manganese compound affected by the Jahn-Teller effect.

Decarboxylative alkylation of carboxylic acids with easily oxidizable functional groups such as phenol and indole functionalities was achieved using a catalytic amount of basic iron(III) acetate, Fe(OAc)(OH), in the presence of benzimidazole under 427 nm LED irradiation. Kinetic analyses of this catalytic reaction revealed that the reaction rate is first-order in alkenes and is linearly correlated with the light intensity; the faster reaction rate for the benzimidazole-ligated species was consistent with the increased absorbance in the visible light region. Wide functional group tolerance for the easily oxidizable groups is ascribed to the weak oxidation ability of the in situ-generated oxo-bridged iron clusters compared with other iron(III) species.

Iron sulfur clusters are critical to a plethora of biological processes; however, little is known about the elementary unit of these clusters, namely the [Fe=S] fragment. Here, we report the synthesis and characterization of a terminal iron sulfido complex. Despite its high spin ( = 5/2) ground state, structural, spectroscopic, and computational characterization provide evidence for iron sulfur multiple bond character.
