Abstract
The complex [Fe(indH)(solvent)3](ClO4)2 (1) has been isolated from the reaction of equimolar amounts of 1,3-bis(2'-pyridylimino)isoindoline (indH) and Fe(ClO4)2 in acetonitrile and characterized by X-ray crystallography and several spectroscopic techniques. It is a suitable catalyst for the oxidation of thioanisoles and benzyl alcohols with H2O2 as the oxidant. Hammett correlations and kinetic isotope effect experiments support the involvement of an electrophilic metalbased oxidant. A metastable green species (2) is observed when 1 is reacted with H2O2 at -40 °C and has a FeIII(μ-O)(μ-O2)FeIII core on the basis of UV/Vis, electron paramagnetic resonance, resonance Raman, and X-ray absorption spectroscopic data.
