A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.

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.
