A new approach to the selective synthesis of (E)-vinyl sulfones has been developed via a Fe/Cu co-catalyzed sulfonylation arylpropiolic acid or phenylacetylene with sulfonyl hydrazides. variety vinyl have obtained in moderate good yields, comparable best results reported so far. The inexpensive method features simple experimental procedure and tolerance substrate.
We have successfully developed an example of copper-catalyzed decarboxylative C(sp2)–C(sp3) coupling reactions via C–H functionalization for the first time. It is noteworthy that our catalytic system very stable, low-cost, palladium-free, ligand-free, and easily accessible.
Reported herein is a novel, useful, visible light-promoted ring-opening functionalization of unstrained cycloalkanols.
An example of highly efficient low-cost ferrocene-catalyzed decarboxylative C(sp2)–C(sp3) coupling reactions via C–H functionalization has been developed successfully. It is noteworthy that nanoparticles Fe3O4 could be used as a reusable catalyst for 7 times in the absence ligand.
The highly effective synthesis of methyl esters from benzylic alcohols, aldehydes, or acids via copper-catalyzed C-C cleavage tert-butyl hydroperoxide is reported in this paper for the first time. Our protocol easily accessible and practical, making it a possible supplement traditional way.
A hydrophobic associating polymer named DiPHAM (acrylamide/sodium acrylamide-2-methylpropanesulfonic/sodium acrylate/N,N-di-n-dodecylacrylamide) with good salt tolerance was synthesized via photo-initiation polymerization. The critical association concentration (CAC) of determined by viscosity changes to be 490 mg/L different concentrations and particle sizes varied under such dynamic conditions. influences aqueous metal ions charges on its solution were investigated measuring apparent...
In order to improve the heat resistance of current clean fracturing fluids, a novel cationic surfactant (VES-T), composed three single-chains and spacer group, was designed synthesized as thickener for fluids. Various performances such VES-T fluid in presence NaSal were evaluated carefully. Study rheological properties demonstrated that fluids with varying concentrations (3⁻5 wt %) have excellent thermal stabilities under ultra-high temperatures ranging from 140 180 °C. Until now, this is...
Catalysis is the second largest application for V after its use as an additive to improve steel production. Molecular complexes of vanadium(V) are particularly useful and efficient catalysts oxidation processes; however, their ability catalyze reductive transformations has yet be fully explored. Here we report first examples polar organic functionality reduction mediated by V. Open-shell VIII that feature a π-radical monoanionic 2,2′:6′,2″-terpyridine ligand (Rtpy•)− functionalized at...
An example of a transition-metal-free, direct, and efficient acetamidosulphenylation reaction alkenes using nitriles as the nucleophiles via radical process is presented. This shows broad substrate scope high regioselectivity provides straightforward access to acetamidosulfide derivatives in moderate yields.
A novel phosphoric acid -mediated synthesis of vinyl sulfones through decarboxylative coupling reactions sodium sulfinates with phenylpropiolic acids is described. This transformation efficient and environmentally friendly.
A category of gemini surfactants with novel structures were designed and synthesized as thickening agents clean fracturing fluids good temperature stability in this research.
Gemini surfactant, as a functionally flexible polymer-like material in the aqueous solution, has attracted increased attention reservoir stimulation of hydraulic fracturing recent decades. A new cationic viscoelastic surfactant named JS-N-JS, which secondary amine spacer group and two ultra-long hydrophobic tails, was synthesized from erucamidopropyl dimethylamine, diethanolamine, thionyl chloride thickener for fluid. Compared with some methylene spacer, JS-N-JS showed lower critical...
Abstract Copper‐catalyzed cross‐coupling reactions of aryl halides and heteroaryl with terminal alkynes were carried out in DMF at 110–130 °C to provide the corresponding coupling products satisfactory‐to‐good yields by using inexpensive 8‐hydoxyquinoline as ligand. Noteworthy is that bifunctional copper catalyst was successfully applied this alkynylation reaction for first time.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Abstract Ligand‐free iron/copper cocatalyzed cross‐coupling reactions of aryl halides with terminal alkynes were carried out to provide the corresponding coupling products in good yields (up 99%). Noteworthy is that this low‐cost, effective and environmentally friendly protocol was first be employed alkynylation couplings.
Taking control: Selective catalysts for olefin dihydroxylation have been generated by the combination of apo-streptavidin and OsO4. Site-directed mutagenesis allows improvement enantioselectivity even inversion enantiopreference in certain cases. Notably allyl phenyl sulfide cis-β-methylstyrene were converted with unprecedented enantiomeric excess. Detailed facts importance to specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or...
