Nanoarchitecturing of open metal site Cr-MOFs for oxodiperoxo molybdenum complexes [MoO(O2)2@En/MIL-100(Cr)] as promising and bifunctional catalyst for selective thioether oxidation

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

Alumina-supported monoperphosphoric acid for selective oxidation of sulfides to sulfoxides

Selective oxidation of aromatic and aliphatic sulfides to the corresponding sulfoxide was achieved by using POCl3/H2O2 and (alumina-supported phosphorus oxychloride)/H2O2. A versatile procedure for th

Curbed of molybdenum oxido-diperoxido complex on ionic liquid body of mesoporous Bipy-PMO-IL as a promising catalyst for selective sulfide oxidation

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.

Competitive and selective Csp3-Br versus Csp2-Br bond activation in palladium-catalysed Suzuki cross-coupling: An experimental and theoretical study of the role of phosphine ligands

Phosphine ligands have been demonstrated to have an effect on reactivity and selectivity in the competitive intramolecular palladium-catalysed Suzuki-Miyaura coupling of dibromo sulfoxide 1a possessing two different hybridised electrophilic carbons. It was found that the bromine bond to the sp3-hybridised carbon is selectively replaced in the presence of unhindered phosphines such as PPh3 or xantphos. The use of hindered phosphine ligands such as P(o-tol)3 and P(1-naphthyl)3 reversed the selectivity, conducting the cross-coupling at the Csp 2-Br. Identical trends were observed in external competition experiments carried out with bromomethyl sulfoxide and different substituted bromoarenes. DFT and DFT/MM calculations showed that the selectivity observed is mainly due to the different facility of the ligands to dissociate. Bisphosphine catalysts favour coupling at the sp3 carbon, whereas monophosphine catalysts prefer the sp2 carbon. Customised catalysts: Proper selection of the phosphine ligand in the palladium catalyst enables a highly intra- and intermolecular selective Suzuki-Miyaura coupling at either Csp 3-Br or Csp2-Br (see figure). DFT and DFT/MM calculations show that the selectivity observed is mainly due to the different facilities of the ligands for dissociation. Copyright

The efficient and chemoselective MoO3-catalyzed oxidation of sulfides to sulfoxides and sulfones with H2O2

Hydrogen peroxide together with MoO3 as catalyst can efficiently and chemoselectivity oxidize sulfides to sulfoxides and sulfones in the presence of other oxidized functional groups in ethanol at 50°C in short reaction times.

Selective oxidation of sulfides to sulfoxides and sulfones using n-butyltriphenylphosphonium dichromate (BunPPh3) 2Cr2O7 in the presence of aluminium chloride in solution and under microwave irradiation

A wide variety of sulfides are efficiently oxidized to their corresponding sulfoxides and sulfones in excellent yields using n-butyltriphenylphosphonium dichromate (BTPPDC) in the presence of aluminium chloride in acetonitrile solution and under microwave irradiation. In addition, selective oxidation of sulfides in the presence of functional groups such as a carbon-carbon double bond, ketone, oxime, aldehyde, ether, and acetal can be considered as a noteworthy advantage of this method.

3-Carboxypyridinium chlorochromate - aluminium chloride - An efficient and inexpensive reagent system for the selective oxidation of sulfides to sulfoxides and sulfones in solution and under microwave irradiation

3-Carboxypyridinium chlorochromate (CPCC) in the presence of aluminium chloride is a very efficient reagent for the selective oxidation of sulfides to sulfoxide and sulfones in solution and under microwave irradiation. It is noteworthy that different functional groups including carbon-carbon double bonds, ketones, oximes, aldehydes, ethers, and acetals were tolerated under these reaction conditions.
