Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, Product Details of 37366-09-9.

The reactivity of [Pt2(mu-S)2 (PPh3)4] towards [RuCl2 (eta6-arene)]2 (arene=C6 H6, C6Me6, p -MeC6 H4Pri = p-cymene), [OsCl2 (eta6- p -cymene)]2 and [MCl2 (eta5-C5Me5)]2 (M=Rh, Ir) have been probed using electrospray ionisation mass spectrometry. In all cases, dicationic products of the type [Pt2(mu-S)2(PPh3)4 ML]2+ (L=pi-hydrocarbon ligand) are observed, and a number of complexes have been prepared on the synthetic scale, isolated as their BPh4- or PF6- salts, and fully characterised. A single-crystal X-ray structure determination on the Ru p-cymene derivative confirms the presence of a pseudo-five-coordinate Ru centre. This resists addition of small donor ligands such as CO and pyridine. The reaction of [Pt2(mu-S)2 (PPh3)4] with RuClCp(PPh3) 2 (Cp=eta5-C5H5) gives [Pt2(mu-S)2(PPh3) 4RuCp]+. In addition, the reaction of [Pt2(mu-S)2(PPh3)4] with the related carbonyl complex [RuCl2(CO)3] 2, monitored by electrospray mass spectrometry, gives [Pt2(mu-S)2(PPh3)4 Ru(CO)3Cl]+.

Application of 92361-49-4, An article , which mentions 92361-49-4, molecular formula is C46H45ClP2Ru. The compound – Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

A series of Cp’Ru(PR3)(PPh3)Cl complexes, where Cp? = Cp*, Dp, Ind, Cp, Tp and PR3 = PTA, PMe3, PPh3, have been used to catalyze the atom transfer radical addition (ATRA) of various chloro substrates (CC14, CHC1 3, and TsCl) to styrene and/or hexene. The complexes Cp *Ru(PTA)(PPh3)Cl, Cp*Ru(PMe 3)(PPh3)Cl, DpRu(PMe3)(PPh3)Cl, and TpRu(PMe3)(PPh3)Cl have been synthesized by ligand exchange reactions with Cp?Ru(PPh3)2Cl and characterized by NMR spectroscopy and X-ray crystallography. An alternative synthesis for CpRu(PMe3)(PPh3)Cl and the solid-state structure of the previously reported complex IndRu(PMe3)(PPh 3)Cl are also described. Among the ruthenium(II) complexes studied, Cp*Ru(PTA)(PPh3)Cl and Cp *Ru(PMe3)(PPh3)Cl were very active at 60 C with TOF values of 1060 and 933 h-1, respectively; Cp *Ru(PPh3)2Cl was the most active for the addition of CCI4 to styrene with a TOF > 960 h-1 at room temperature. Total turnovers (TTO) in excess of 80000 for the addition of CC14 to hexene were obtained for the Cp* complexes, making these complexes the most active and robust catalysts for ATRA reported to date.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 92361-49-4, help many people in the next few years., Application of 92361-49-4

Electric Literature of 246047-72-3, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 246047-72-3, C46H65Cl2N2PRu. A document type is Article, introducing its new discovery.

A 95% yield in the cross metathesis of acrylonitrile with a model olefin is achieved at 25 C with only 3 mol % of the new air-stable ruthenium catalyst 1f shown in the enclosed structural diagram. Even more remarkable are the performances of its boosted version 1g incorporating an electron-withdrawing group. Both these new enhanced versions of Hoveyda catalyst are readily available from Grubbs second generation precatalyst upon reaction with a styrenyl ether the end group of which has been functionalized by an ester function. The latter acts as a weakly coordinating ligand allowing to reach a desirable balance between antinomic properties such as the catalyst’s stability, a high activity for challenging substrates, and a high initiation rate.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

The cross-metathesis of vinyltrialkoxy- and vinyltrisiloxysilanes as well as divinyltetra-ethoxydisiloxane with various allyl alkyl ethers catalyzed by Cl2(PCy3)2Ru(=CHPh) (I) is presented. The reaction is accompanied by self-metathesis of allyl alkyl ethers. The catalytic examination presented in this paper has allowed us to develop optimum conditions for selective synthesis of 1-silyl-3-alkoxy-propenes (R?O)3SiCH=CHOR (where R = Et, n-Bu, Cy, Ph, PhCH2, Gly, Me3Si, R? = Me, Et, SiMe3) with high preference of the E-isomers (E/Z > 7:1). This allowed the selective isolation of the E-isomer. A stoichiometric study of I with substrates has been carried out. The results are discussed on the basis of a metallacarbene mechanism.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 246047-72-3 is helpful to your research., COA of Formula: C46H65Cl2N2PRu

37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 37366-09-9, Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer

As hypoxia is an important factor to limit chemotherapeutic efficacy in tumors, we herein report three ruthenium(II)-arene complexes containing a hypoxia inducible factor-1alpha inhibitor (YC-1), which endow the organometallic complexes with potential for hypoxia targeting. In vitro tests showed the resulting complexes had higher anticancer activities in hypoxia than in normoxia against the tested cancer cell lines. Western blot analysis revealed that complexes 1-3 blocked HIF-1alpha protein accumulation under hypoxic conditions. Moreover, these complexes displayed much less cytotoxicity toward the normal human umbilical vein endothelial cell line (HUVEC), indicating that complexes 1-3 may be selectively cytotoxic for human cancer cell lines. These findings proved that ligation with YC-1 endowed these organometallic ruthenium(II) complexes with potential for hypoxia targeting in addition to enhancing their anticancer activities.

Microwave-assisted or thermal reaction of the (R-bpy)2RuCl2 solutions with substituted bibenzimidazoles, 1,10 phenanthroline or bipyrimidine in dmf/water mixtures resulted in the formation of mixed ligand complexes of the type [(R-bpy) 2Ru(L-L)]Cl2. Complexes of the type (R-bpy) 2RuCl2 (R: H, Me, tert-but) were synthesised by microwave-activated reactions of [Ru(cod)Cl2]n with substituted 2,2?-bipyridines in dimethylformamide as the solvent. The complexes were isolated in high yields and high purity from the reaction mixture. Microwave-assisted or thermal reaction of the (R-bpy) 2RuCl2 solutions with substituted bibenzimidazoles, 1,10 phenanthroline or bipyrimidine in dmf/water mixtures resulted in the formation of mixed ligand complexes of the type [(R-bpy)2Ru(L-L)]Cl 2.

The disclosure provides methods of converting a lower alcohol (e.g., ethanol) to a higher alcohol (e.g., butanol) in the presence of a water stable transition metal catalyst comprising a Group VIII transition metal and a polydentate nitrogen donor ligand. The methods described in the disclosure can be carried out in the presence of water and achieve high purities of the higher alcohols.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C20H16Cl2N4Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
