“…The combination of organic and inorganic component's features along with structural anisotropy would lead to improve their functionalities and performances. [18][19][20][21][22][23][24][25] Moreover, overoxidation of the sulfoxides to sulfones is a common problem during the oxidation of sulfides [26,27] that has garnered attention from the synthetic community. [15][16][17] Therefore, a large number of methods, procedures and oxidizing agents have been proposed for this type of transformation.…”

A novel hybrid material, (Ce III -Mo VI )O x /aniline, with rod-like morphology is synthesized through a wet chemical method using Mo 3 O 10 (C 6 H 5 NH 3 ) 2 .2H 2 O nanowires as precursor. The synthesized materials are characterized by XRD, XPS, SEM, TEM, FTIR, Raman, UV-Vis, TGA, and elemental analysis. Also, their catalytic activities as a hybrid catalyst are tested in the selective oxidation of sulfides using hydrogen peroxide as a green oxidant. The proposed novel hybrid catalyst shows an excellent performance under green conditions at mild temperature. Furthermore, the scalability of the oxidation reaction is shown by making multi-gram quantities at optimized conditions.

“…[16,17] The derivatives of heteroaryl sulfones constitute core units of many important molecules which are used as drugs and potential precursors [18] (Figure 1). [36][37][38] Because of the disadvantages of the methods discussed above, in this paper we introduce a new nanocatalyst, namely BNPs-silica-NHSO 3 H (BNPs-SiO 2 @(CH 2 ) 3 NHSO 3 H), for selective oxidation of sulfides to sulfones under mild and green conditions (Scheme 1). Several homogeneous and heterogeneous oxidant-based catalytic systems have been reported for the oxidation of sulfides.…”

Reusable boehmite nanoparticles-silica-NHSO 3 H (BNPs-SiO 2 @(CH 2 ) 3 NHSO 3 H) was found to be an efficient heterogeneous nanocatalyst for the selective oxidation of sulfides to sulfones in the presence of H 2 O 2 . Excellent yields, easy and quick isolation of products, short reaction times and excellent selectivity are the main advantages of this method. The catalyst was characterized using Fourier transform infrared spectroscopy, energy-dispersive X-ray analysis, X-ray diffraction, and transmission and scanning electron microscopies.

“…Several authors have proposed different supports for the catalyst in oxidation of organosulfur compounds to sulfones by H 2 O 2 [7][8][9][10]. In general, these catalysts have shown good OD activities using the model system (dibenzothiophene) whereas in the real processes the catalyst activity decreases [6].…”

Theoretical Study of Peroxo- and Diperoxomolybdate Formation as Catalysts in the Oxidative Desulfurization of Diesel

The desulfurization is a very important process in the fuel production with less sulfur content, for this reason, several catalysts in different supports and conditions have been tested, however in the most of cases the reaction mechanism is not studied because it is very complicated. In the present work, the molybdate catalyst formation is studied by Density Functional Theory to demonstrate that this catalyst could be used in the oxidative desulfurization. As it is well-know, the solvent influence is very important in the reaction mechanism studies. There are several methodologies where the solvent effect could be considered. In this study the solvent was simulated by three ways: the first one by explicit n-water molecules (with n = 0, 1 and 2), the second one by PCM theory and the last by a combination of the two first. The results show that the structure called I01 is the most probable catalyst in the oxidative desulfurization reaction; additionally the effect of the water molecule surrounding this structure is fundamental to stabilize it. Finally this reactive structure could be formed in water and acetonitrile phases.
