Protonation of a Peroxodiiron(III) Complex and Conversion to a Diiron(III/IV) Intermediate: Implications for Proton-assisted O-O Bond Cleavage in Nonheme Diiron Enzymes

Oxygenation of a diiron(II) complex,[Fe(II)(2)(μ-OH)(2)(BnBQA)(2)(NCMe)(2)](2+ )(2) (where BnBQA is N-benzyl-N,N-bis(2-quinolinylmethyl)amine) results in the formation of a metastable peroxodiferric intermediate (3). Treatment of 3 with strong acid affords its conjugate acid 4 in which the (μ-oxo)(μ...
