    • Probing the mechanism of C-H activation: Oxidation of methylcubane by soluble methane monooxygenase from Methylosinus trichosporium OB3b
    • The use of methylcubane with the reconstituted MMO system from M. trichosporium OB3b yields both cubylmethanol and methylcubanols. An unexpected regioselectivity towards the methyl hydroxylation versus cubyl hydroxylation is observed, indicating steric effects on the reaction. The results suggest the formation of a radical intermediate in the reaction and support a radical-based mechanism.

    • Formation of Fe(III)Fe(IV) species from the reaction between a diron(II) complex and dioxygen: Relevance to ribonucleotide reductase intermediate X
    • Lippard and co-workers describe in this paper the first evidence for dioxygen oxidation of a diiron(II) complex to an Fe(III)Fe(IV) model compound for the key intermediate R2-X found in the reaction cycle of the R2 subunit of ribonucleotide reductase. The formation of this species is the first example of a process that utilizes dioxygen to access the Fe(IV) oxidation state in a synthetic model complex. It was identified and spectroscopically characterized by EPR, UV/Vis and Mössbauer spectroscopy.
