| 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. |
