A new concept for aryl−aryl coupling that involves oxidative decarbonylative of aryl C−H bonds and readily available aldehydes has been developed, achieving the union with complete control reaction sites.
A novel, direct para-selective oxidative cross-coupling of benzene derivatives with cycloalkanes catalyzed by ruthenium was developed. wide range arenes bearing electron-withdrawing substituents functionalized directly simple high para-selectivity; electron-donating groups were mainly para-functionalized. Benzoic acid can be used directly.
A ruthenium-catalyzed olefination via decarbonylative addition of aldehydes and alkynes has been developed. strong electronic effect high chemoselectivity between aromatic aliphatic were observed in this reaction.
An iron-catalyzed arylation of azoles with aromatic aldehydes using oxygen as oxidant has been discovered. The reaction proceeded well for a range different substrates under oxidative conditions.
Lithio siloles of diversified structures and substitution patterns were highly efficiently formed from readily available silyl 1,4-dilithio-1,3-butadienes via novel intramolecular skeletal rearrangements.
Abstract A ruthenium‐catalyzed oxidative homo‐coupling reaction of 2‐arylpyridines via CH activation was developed. The could tolerate various functional groups on both the aryl and pyridyl rings to afford a series dimerized products with iron(III) chloride (FeCl 3 ) as stoichiometric oxidant. tentative mechanism proposed for this CH/CH homo‐coupling.
A novel rhodium-catalyzed oxidative decarbonylative homocoupling of aromatic aldehydes to generate biaryls and diarylketones selectively efficiently, triggered by the choice different phosphine ligands.
Abstract The decarbonylative coupling of aldehydes and norbornene analogues was realized for the first time by using a rhodium(I) catalyst.
A novel method for the formation of isolated C═C bonds was developed via a ruthenium-catalyzed decarbonylative addition aliphatic aldehydes and alkynes. An unprecedented complete switch chemoselectivity from aromatic to observed simpl y by using tri(2,4,6-trismethoxyphenyl)phosphine as ligand. synthesis this an insect sex pheromone demonstrated.
In order to inhibit the active free radicals in oxidation process of coal at low temperatures, use catechin as inhibitors is proposed. A set-up thermogravimetric analyzer-Fourier-transform infrared spectrometer-gas chromatograph/mass spectrometer (TG-FTIR-GCMS) has been used measure mass loss and gaseous products evolved during heating raw coal-catechin samples. The experimental results show that epicatechin (EC) can provide H· combined with coal, thereby inhibiting reaction oxygen, leading...
2,5-Bis(alkynylsilyl)-1-zirconacyclopentadienes 3 were formed highly regio- and chemoselectively in excellent yield by the homocoupling reaction of 2 equiv bis(alkynyl)silanes 1 mediated a low-valent zirconocene species (Negishi reagent) generated situ from Cp2ZrBu2. Single-crystal X-ray structural analysis 2,5-bis(phenylalkynyldimethylsilyl)-1-zirconacyclopentadiene (3a) revealed sandwich-type conformation. Hydrolysis or halogenation these zirconacyclopentadienes afforded multisubstituted...
Stereodefined multisubstituted 1-cyano- and 1,4-dicyano-1,3-butadiene derivatives were obtained in excellent yields of the isolated product from their corresponding monohalo- dihalobutadienes CuCN. This reaction proceeded with high stereoselectivity retention stereochemistry starting halobutadienes. A study utility thus-obtained was demonstrated by reactions organolithium reagents. 2H-Pyrrole or iminocyclopentadiene formed 1-cyano-4-halo-1,3-butadienes When 1,4-dicyano-1,3-butadienes treated...
Self-hardening thermoplastic foams (STFs), as an innovative technology mainly synthesized using 1 wt. % auxiliary agent (organic acid and polycaprolactone) 99 foaming solution (polyethylene oxide, sodium silicate solution, dodecyl sulfate, water), were proposed to inhibit the self-oxidation of coal. When gas was injected into synthetic self-made device with single power source, due synergistic action surfactant polyethylene aqueous foam excellent wetting ability initially formed, followed by...
Macrophages are innate immune cells connected with the development of inflammation. Retinoic acid has previously been proved to have anti-inflammatory and anti-arthritic properties. However, exact mechanism through which retinoic modulates arthritis remains unclear. This study aimed investigate whether ameliorates rheumatoid by modulating macrophage polarization. used treat mice adjuvant evaluated effects score, thermal nociceptive sensitization test, histopathologic examination...
