To achieve green chemistry goals and also to reduce the cost of catalysts as well as to avoid producing toxic wastes and show the importance of separation and recycling of catalysts from the reaction medium, in this work, we describe the preparation and characterization of magnetic acidic boehmite nanoparticles as a heterogeneous catalyst, which is called Fe3O4?BNPs?SiO2-SO3H. This catalyst works efficiently in the selective oxidation of sulfides to sulfoxides or sulfones in the presence of H2O2 as a green oxidant. It can easily be separated from the reaction medium by using an external magnet and it was recycled 6 times without loss of magnetic catalytic properties.
A route to benzylic arylsulfoxides from β-ketosulfoxides

The K2CO3-mediated benzylation of β-ketosulfoxides 4 with 2.0?equiv of benzylic halides 5 affords benzylic arylsulfoxides 6 in moderate yields along with trace amounts of chalcones 7. The products 6 are assumed to form in situ intermediates of sulfenate anions from β-ketosulfoxides which are commonly involved in carbon–sulfur bond formation. A plausible mechanism has been proposed.
Tetrabutylammonium tribromide impregnated MCM-48 as a heterogeneous catalyst for selective oxidation of sulfides

, p. 38044 - 38047 (2015/06/30)
We report here tetrabutylammonium tribromide supported on MCM-48 as a highly efficient heterogeneous catalyst for the selective oxidation of sulfides, in ethanolic medium using hydrogen peroxide as an oxidant. The aforementioned oxidation reactions were found to proceed rapidly (20 min) and in good yield (85-99%) (17 examples). The oxidation products were characterized by 1H NMR, 13C NMR and elemental analysis. The catalytic properties were analysed by TEM, XRD and BET-surface area measurement. No over-oxidation of the substrates was observed (analysed by GC), and the catalyst was effectively recycled for five consecutive cycles without any significant loss in its catalytic activity.
