Selective Heck reaction of electron-rich aryl bromides with cyclic alkenones

A simple and efficient protocol for the Heck reaction of cyclic alkenones with electron-rich aryl bromides has been developed. A ligand combination of X-Phos and tri-tert-butylphosphonium hydrogen tetrafluoroborate in the presence of Pd(PPh3)2Cl2 and Na2CO3 in DMSO was found to be efficient and selective for electron-rich aryl bromides with high substrate scope for cyclic alkenones.

Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, 5631-96-9, the author is Eshghi, Hossein and a compound is mentioned, 5631-96-9, 2-(2-Chloroethoxy)tetrahydro-2H-pyran, introducing its new discovery.

Phosphorus pentoxide as an efficient catalyst for the tetrahydropyranylation of alcohols under solvent-free conditions

A facile and efficient method for the preparation of tetrahydropyranyl ethers from alcohols is improved in solvent-free media. These reactions are catalyzed by P2O5 and afford various tetrahydropyranyl ethers in shorter reaction time, with good to excellent yields (75-95%) at room temperature. This method is also compatible with substrates containing acid-sensitive functional groups.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 5631-96-9!, 5631-96-9

Upgrading pine sawdust pyrolysis oil to green biofuels by HDO over zinc-assisted Pd/C catalyst

Upgrading pyrolysis oil by hydrodeoxygenation (HDO) is a promising route for the production of advanced biofuels. The proper reaction conditions and catalysts are important for the success of this process. Previously our research group investigated the ratio of Zn and Pd on the synergistic effect for HDO bio-oil upgrading. This present research focuses on determining the optimal reaction conditions for HDO conversion of pyrolysis oil produced from pine sawdust. Temperatures of 150, 200 and 250C and hydrogen pressures of 1.38, 2.76 and 4.14 MPa were evaluated. Syngas, liquids and coke were the primary products evaluated. Syngas was characterized using a Gas chromatography (GC). The liquids were characterized using a Gas chromatography-mass spectrometry (GC-MS). Increasing reaction temperature resulted in increased coke yields. Treatment at 250C and 1.38 MPa resulted in the highest hydrocarbon content (6.06%). The treatment at 200C and 1.38 MPa produced the largest amounts of hydrocarbons in C6-C12 range (5.07%). The physicochemical characterizations further support the GCMS results. Syngas analysis revealed that higher hydrogen pressure leads to increased hydrogen consumption and results in more oxy-compounds conversion to hydrocarbons. The syngas analysis also supports the liquid analysis result.

Synthesis, characterization, DNA interaction and cleavage, and in vitro cytotoxicity of copper(ii) mixed-ligand complexes with 2-phenyl-3-hydroxy-4(1H)- quinolinone

A series of mixed-ligand complexes [Cu(qui)(L)]NO3¡¤ xH2O (1-6), where Hqui = 2-phenyl-3-hydroxy-4(1H)-quinolinone, L = 2,2?-bipyridine (bpy) (1), 1,10-phenanthroline (phen) (2), bis(2-pyridyl)amine (ambpy) (3), 5-methyl-1,10-phenanthroline (mphen) (4), 5-nitro-1,10-phenanthroline (nphen) (5) and bathophenanthroline (bphen) (6), have been synthesized and fully characterized. The X-ray structures of [Cu(qui)(phen)]NO3¡¤H2O (2) and [Cu(qui)(ambpy)] NO3 (3a) show a slightly distorted square-planar geometry in the vicinity of the central copper(ii) atom. An in vitro cytotoxicity study of the complexes found significant activity against human osteosarcoma (HOS) and human breast adenocarcinoma (MCF7) cell lines, with the best results for complex 6, where IC50 equals to 2.1 ¡À 0.2 muM, and 2.2 ¡À 0.4 muM, respectively.
