| Abstract: | Dibenzothiophene (DBT), a common component of crude oil, is a widespread environmental pollutant with known adverse effects. Oxidation of DBT to dibenzothiophene sulfone has been examined using in situ generated high-valent oxo-iron(IV) complexes. The reactivities and the corresponding thermodynamic parameters are evaluated and compared with those for simple S-oxidation (thioanisole) reactions. Among the catalysts examined, [FeII(Bn-Tpen)]2+ is found to be a more efficient oxidant over [FeII(N4Py)]2+. The order of the reactivity and the evaluated thermodynamic parameters signify the role of the electron delocalization due to benzene rings for DBT oxidation. |
