Ruthenium catalysts

Synthetic Route of 172222-30-9. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 172222-30-9, Name is Benzylidenebis(tricyclohexylphosphine)dichlororuthenium

The scope of a stereoselective three-step approach for the synthesis of sugar derived spiroketals is presented. The methodology consists of Grignard addition of vinyl- or allylmagnesium bromide to a carbohydrate lactone, followed by K-10 clay mediated glycosidation with a terminal alkenol and subsequent ring-closing metathesis of the resulting diene. The generality of this procedure is demonstrated by the synthesis of various pyranose- and furanose-derived spiroketals, as well as more advanced tricyclic spiroketal derivatives. It is shown that functionalisation of the double bond in the resulting spiroketals leads to fused polycyclic ethers.

Recent emphasis on green chemistry has called for the exploration of more environmentally friendly media such as supercritical CO2 and water. Ionic liquids offer interesting alternative reaction media to volatile organic solvents due to their low vapor pressure and the possibility of recycling. Towards this end, we have explored the addition of activated methylenes to alkenes in ionic liquids and under neat conditions. These alternatives are advantageous over our previous method, which requires the use of toxic organic solvent and expensive catalysts. Our results show that 1,3-diketones can be added to alkenes in ionic liquid with the use of 10% SnBr4 or under solventless conditions with 10% Cu(OTf)2. Up to 85% yield can be achieved using these new methodologies.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 10049-08-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10049-08-8, in my other articles.

The ruthenium(II) triazenido complex [RuCl(ClC6H 4N3C6H4Cl)(p-cymene)] (1) is obtained by the reaction of silver bis(p-chlorphenyl)triazenid with [RuCl 2(p-cymene)]2 in CH2Cl2, and forms air stable, orange yellow crystals. It crystallizes as 1·CH 2Cl2 in the orthorhombic space group Pbca with the lattice parameters a = 3134.3(3), b = 2105.7(2), c = 769.15(4) pm and Z = 8. In the diamagnetic mononuclear complex 1 the chelating triazenido ligand coordinates with the atoms N(1) and N(3). p-Cymene binds eta6 with its C 6 ring. The reaction of the etherphosphane complex [RuCl 2(Ph2PCH2C4H7O 2)2] with 1,3-bis(p-tolyl)triazenid in THF yields the complex [RuCl(tolyl-N3-tolyl)(Ph2PCH2C 4H7O2)2] (2). 2 forms monoclinic, red crystals with the space group P21/c and a = 1521.0(2), b = 1451.8(2), c = 2073.7(2) pm, beta = 99.29(1) and Z = 4. It is air stable and diamagnetic. The triazenide ion coordinates with the atoms N(1) and N(3). One of the two etherphosphane ligands is chelating and coordinates with the P atom and one O atom, while the other ligand binds in a monodentate fashion with its P atom, resulting in a coordination number of six for the RuII. [Ag(tolyl-N5-tolyl)]2 reacts in THF with [RuCl 2(C6H6)]2 to afford the air stable, diamagnetic pentaazadienido complex [RuCl(tolyl-N5-tolyl)(C 6H6)] (3). 3 forms monoclinic, red crystals with the space group P21/c and a = 1462.4(1), b = 1056.51(8), c = 1371.4(1) pm, beta = 114.36(1) and Z = 4. The chelating pentaazadienido ligand coordinates with the atoms N(1) and N(3) at the divalent Ru atom. The benzene molecule binds eta6 with its pi system.

Metal-coordinated “gamma-lactam-capped” and “imide-capped” 1,10-phenanthroline ligands are reported. Whereas the imide-functionalized ligand 1,10-phenanthroline-5,6-carboximide could not be obtained as a free ligand, probably due to its extremely low solubility, we developed a protocol to first introduce the more soluble 1,10-phenanthrolino[5, 6-c]pyrrole in the ligand sphere of cyclometalated iridium(III) complexes, followed by the oxidation of the pyrrole moiety to a maleimide utilizing a peroxybenzoic acid. The hydrogen bond donor-acceptor properties of the new ligands should make them suitable building blocks for the design of metal-based protein binders. Furthermore, we unexpectedly found that bis-cyclometalated iridium(III) complexes coordinated to 1,10-phenanthroline-5,6-carboximide display luminescence properties that are dependent on the protonation state of the maleimide NH group. It can be envisioned to exploit this behavior for the real-time monitoring of hydrogen bonding interactions in biological systems.

A ruthenium trinuclear polyazine complex was synthesized and subsequently immobilized through complexation to a graphene oxide support containing phenanthroline ligands (GO-phen). The developed photocatalyst was used for the photocatalytic reduction of CO2 to methanol, using a 20 watt white cold LED flood light, in a dimethyl formamide-water mixture containing triethylamine as a reductive quencher. After 48 h illumination, the yield of methanol was found to be 3977.57 ± 5.60 mumol gcat -1. The developed photocatalyst exhibited a higher photocatalytic activity than graphene oxide, which provided a yield of 2201.40 ± 8.76 mumol gcat-1. After the reaction, the catalyst was easily recovered and reused for four subsequent runs without a significant loss of catalytic activity and no leaching of the metal/ligand was detected during the reaction.

The enantioselective synthesis of passifloricin A has been achieved in high diastereomeric excess. The 1,3-polyol moiety was constructed by iterative proline-catalyzed sequential alpha-aminoxylation and Horner-Wadsworth-Emmons (HWE) olefination of aldehydes while the synthesis of lactone moiety was achieved by ring-closing metathesis (RCM).

Thioredoxin reductase (TrxR), a major component of the thioredoxin system, makes a critical role in regulating cellular redox signaling and is found to be overexpressed in many human cancer cells. TrxR has become an attractive target for anticancer agents. In this work, three Ru(II) complexes with salicylate as ligand, [Ru(phen)2(SA)] (phen = 1,10-phenanthroline, SA = salicylate, 1), [Ru(dmb)2(SA)] (dmb = 4,4?-dimethyl-2,2?-bipyridine, 2) and [Ru(bpy)2(SA)] (bpy = 2,2?-bipyridine, 3), were synthesized and characterized. The anticancer effect exerted by them was evaluated. Complex 1 was found to exhibit obvious anticancer activity, in comparison with cisplatin, against cancer cell lines, while displaying low toxicity to the normal cell line BEAS-2B. The mechanism of complex 1 cancer cell growth suppress was investigated in A549 cells. Complex 1 exerted its anticancer through inducing apoptosis and triggering cell cycle arrest at the G0/G1 phase. Complex 1 can selectively inhibit TrxR activity and thus promote the generation and accumulation of reactive oxygen species (ROS), which subsequently trigger mitochondrial dysfunction and DNA damage, activate oxidative stress-sensitive mitogen activated protein kinase (MAPK), and suppress the protein kinase B (PKB or AKT) signal pathway, resulting in apoptosis in A549 cells.

The conversion of seed oil based feedstocks such as methyl oleate into useful commercial raw materials via olefin metathesis has been a research focus for decades, due to their low cost and renewable supply, but technical success has been limited due to poor catalyst activities and turnovers. We report here recent studies on the cross-metathesis of methyl oleate with ethylene (ethenolysis) catalyzed by bis(tricyclohexylphosphine)benzylideneruthenium dichloride (1). At 25C/60 psig of ethylene, catalysis by results in the highly selective formation of 1-decene and methyl 9-decenoate. However, reactivity losses limit the catalyst turnovers well below commercial viability in batch reactor operation. In an attempt to address the limitations of this chemistry, a combination of an experimental evaluation of the impact of process parameters, a detailed analysis of the fundamental reaction steps, kinetic modeling, and molecular modeling has been applied to develop a more detailed understanding of this complex catalytic pathway. These fundamental studies have led to a more complete understanding of the factors impacting catalyst performance and the identification of approaches necessary to achieve an economically viable process.
