Hydrogen-Atom Transfer Oxidation with H₂O₂ Catalyzed by [FeII(1,2-bis(2,2'-bipyridyl-6-yl)ethane(H₂O)₂]²⁺: Likely Involvement of a (μ-Hydroxo)(μ-1,2-peroxo)diiron(III) Intermediate.

ABSTRACT: The iron(II) triflate complex (1) of 1,2-bis(2,2'-bipyridyl-6-yl)ethane, with two bipyridine moieties connected by an ethane bridge, was prepared. Addition of aqueous 30% H₂O₂ to an acetonitrile solution of 1 yielded 2, a green compound with λ_max=710 nm. Moessbauer measurements on 2 showed a doublet with an isomer shift (δ) of 0.35 mm/s and a quadrupole splitting (ΔE_Q) of 0.86 mm/s, indicative of an antiferromagnetically coupled diferric complex. Resonance Raman spectra showed peaks at 883, 556 and 451 cm^-1 that downshifted to 832, 540 and 441 cm^-1 when 1 was treated with H₂¹⁸O₂. All the spectroscopic data support the initial formation of a (μ-hydroxo
