In this paper, trifluoroethanol (TFE) was confined into SBA-15 and compared with its similar non-fluorous systems in the metal-free oxidation of sulfides to sulfoxides in the presence of H2O2. This catalytic system successfully perfo
Sulfoxide and Sulfone Synthesis via Electrochemical Oxidation of Sulfides

The oxidation of diaryl sulfides and aryl alkyl sulfides to the corresponding sulfoxides and sulfones under electrochemical conditions is reported. Sulfoxides are selectively obtained in good yield under a constant current of 5 mA for 10 h in DMF, while sulfones are formed as the major product under a constant current of 10 or 20 mA for 10 h in MeOH. The oxygen of both the sulfoxide and sulfone function is derived from water.
Post-synthetically modified SBA-15 with NH2-coordinately immobilized iron-oxine: SBA-15/NH2-FeQ3 as a Fenton-like hybrid catalyst for the selective oxidation of organic sulfides

A new modified SBA-15 meso-material with NH2-coordinately immobilized "iron-oxine" was fabricated by stepwise covalent grafting of -NH2 and then NH2-coordinate immobilization of tris(8-quinolinolato)iron onto the channels of SBA-15. The structural properties and chemical nature of SBA-15/NH2-FeQ3 were characterized by FTIR, scanning electron microscopy (SEM), SEM-EDX/mapping, transmission electron microscopy (TEM), low angle X-ray diffraction (L-XRD), thermal gravimetric analysis (TGA), N2-adsorption-desorption isotherms (BET) and atomic absorption spectroscopy (AAS). A Fenton-like green and eco-friendly procedure for the catalytic oxidation of aromatic organic sulfides to sulfones using H2O2 was investigated for the synthesised Fe/SBA-15 catalyst. This porous catalyst was found to be reusable for ten runs without appreciable change in the activity, or the composition of the catalyst.
