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.

Pd/NHC-catalyzed arylsulfonylation of boronic acids: A general and direct protocol to access diarylsulfones

For the first time, robust NHC-Pd complexes have been demonstrated as highly efficient catalysts in the direct arylsulfonylation of boronic acids. Remarkably, a broad number of diaryliodonium salts as powerful electrophilic arylation reagents are well compatible to form functional ortho-substituted diarylsulfones in satisfactory yields. Owing to the stronger σ-donor and weaker π-acceptor properties, the acenaphthoimidazolylidene ligands exhibit higher catalytic activities towards this challenging one-step arylsulfonylation reaction.

Selective Synthesis of ortho-Substituted Diarylsulfones by Using NHC-Au Catalysts under Mild Conditions

A single-step gold(I)-catalyzed chemoselective protocol to access ortho-substituted diarylsulfones has been established. Acenaphthoimidazolylidene gold complexes are effective catalysts for the arylsulfonylation of boronic acids by potassium metabisulfite (K2S2O5) and diaryliodonium salts to access (poly-)ortho-substituted diarylsulfones even in gram scale. Unlike the transition metal-catalyzed two-component coupling systems, the sterically hindered aryl groups in diaryliodonium salts are preferentially transferred over less bulky ones to form synthetically difficult targets, including those of pharmaceutical importance.
