In this work, we introduce a novel bipyridinium ionic liquid bridged periodic mesoporous organosilicas (Bipy-PMOs-IL) which is used as the support to immobilize oxygen-rich Molybdenum (VI)-based oxido-peroxido complex (MoO(O2)2?Bipy-PMO-IL). Several techniques such as Small-angle X-ray scattering (SAXS), low angle XRD, FE-SEM (field emission scanning electron microscope), TEM (transmission electron microscope), N2 adsorption-desorption analyses (BET), atomic absorption spectroscopy (AAS), Fourier-transform infrared spectroscopy (FT-IR) and Energy Dispersive X-Ray (EDS or EDX) were used to characterize this nanomaterial. Also, the catalytic activities of the MoO(O2)2?Bipy-PMO-IL as a hybrid catalyst is tested in the selective oxidation of sulfides in water by using H2O2 (30%) as an eco-friendly and green co-oxidant. The as-prepared novel catalyst shows high to excellent performance under optimum reaction conditions at ambient room temperature. The obtained results in this work show several outstanding advantages, such as green conditions, high product yields, easy work-up, easy preparation and acceptable reusability of the catalyst for at least 5 runs. To study the IL effect in immobilization of Mo-complex, in a comparison study, the MoO(O2)2?Bipy-PMO-IL materials and MoO(O2)2?SBA-15 (with simple SiO2 body, no IL) body were employed for sulfide oxidation. After the treatment, the Mo?Bipy-PMO-IL with IL body in channels was reused for subsequent experiments (5 runs), but in Mo?SBA-15 after second run the yield was decreased dramatically.
Metal-free oxidative coupling of alkyl chlorides with thiols: An efficient access to sulfoxides
Liu, Qian,Zhao, Xiaoqian,Xu, Feng,Li, Gaoqiang
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.

supporting information, 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.

In this work, open metal site metal-organic framework of MIL-100(Cr) was selected as a support for the multi-step grafting of molybdenum complexes. The oxodiperoxo molybdenum complexes were coordinated onto the ethylene diamine-decorated MIL-100(Cr) pore

A novel palladium-catalyzed ortho-C(sp2)-H olefination protocol has been developed by the use of sulfoxide as the directing group. Importantly, relatively remote coordination can be accessed to achieve the ortho olefination of benzyl, 2-arylethyl, and 3-arylpropenyl sulfoxide substrates, and the olefinated sulfoxide can be easily transformed to other functionalities.

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.
