Selective oxidation of sulfides to sulfoxides is achieved by H2O2 using HNO3 as the promotor. Aromatic and aliphatic sulfides are oxidized to sulfoxides in excellent yields and short reaction times. Different functional groups including C-C double bond, ester, ketone, acetal, alcohol, and oxime groups are tolerated under this reaction condition.

A new heterogeneous catalytic system was prepared by immobilization of tungstate ions on a cross-linked poly(ionic liquid) nanogel. The solid nanogel was easily synthesized by a surfactant-less method. The resulting catalyst was highly active in selective

Porous materials based on chromium (III) terephthalate metal organic frameworks (Cr-MIL(101)) and their new composites with vanadium oxide has emerged as a potential catalyst because of its high specific surface area, tunable pore size, and unique structure. The structural and textural characterization of V@MIL(101) were done using FTIR, X-ray diffraction, N 2 adsorption-desorption, and TEM. XRD and adsorption-desorption analysis shows that the mesostructure of MIL-101 remains intact after vanadium oxide modifications, while spectral technique show the successful immobilizing of the neat vanadium oxide inside the MIL-101 cavities. These new catalysts were found to be highly effective for selective oxidation of sulfides to sulfoxides and sulfones with H2O2 at room temperature and the 4.2% V@MIL(101) catalyst showed the highest activity. The PW12@MCF im heterogeneous system showed high catalytic oxidative activity in the treatment of commodity gasoline.

supporting information, (2019/12/27)
An efficient and step-economical access to sulfoxides from thiols and alkyl halides in the presence of I2O5 and DBU via direct oxidative couplings is described here. It is the first case that combined Williamson sulfide synthesis and subsequent sulfide oxidation into one step manipulation for sulfoxides preparation. This protocol features wide substrate scope, mild and metal-free conditons, the use of naturally abundant starting materials and avoidance of over-oxidation.

, p. 2076 - 2079 (2018/04/16)
A copper-catalyzed sulfoxidation of benzylic C-H bonds by nondirected oxidative C(sp3)-H activation was developed. The process proceeds via sulfenate anions, which are generated by base-triggered elimination of β-sulfinyl esters and benzyl radicals. The functional group tolerance is high, and the product yields are good.

A general approach to sulfur-bridged polycycles by palladium-catalyzed double C(sp2)-H bond oxidative cyclization is presented. This protocol afforded diverse sulfur-bridged five-, six-, and seven-membered polycycles in moderate to good yields with a tolerance for a wide variety of functional groups. A sulfide-bridged six-membered pyrene-thienoacene compound was synthesized readily using this method, and excellent performance for photoluminescence quantum yield was observed.
