| Abstract: | A reusable solid catalyst, MnFe1.8Cu0.15Ru0.05O4, has been developed as an effective catalyst for the aerobic oxidation of sulfides and sulfoxides to sulfones. The ruthenium
modified spinel catalyst is the first example reported for such reaction under mild condition with molecular oxygen as the
only oxidant. The oxidation reaction proceeded via an electrophilic attack of the oxygen atom of the catalyst on the electron-rich
sulfur atom of the substrate. |
