A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article，once mentioned of 32993-05-8, COA of Formula: C41H35ClP2Ru

The complexes [CpRuCl(PEt3)2 (1) and [CpRuCl(PMeiPr2)(PPh3)] (2) react with H2S in EtOH in the presence of NaBPh4 furnishing the green persulfide derivatives [{CpRu(L)}2-(mu-S2)][BPh4]2 (L = (PEt3)2, (PMeiPr2)(PPh3)), which were also obtained by reaction of 1 or 2 with elemental sulfur and NaBPh4 in MeOH. At variance with this, the reaction of [Cp*RuCl-(PEt3)2] (3) with H2S in EtOH afforded the RuIV hydrido-metallothiol [Cp*RuH(SH)(PEt3)2]-[BPh4], which has been structurally characterized, derived from the oxidative addition of SH2 to the electron-rich RuII moiety {[Cp*Ru(PEt3)2]+}. This compound is oxidized to yield the persulfide complex [{Cp*Ru(PEt3)2}2(mu-S 2)][BPh4]2, which was also obtained by reaction of 3 with elemental sulfur. The reaction of 1, 2, and 3 with 2-mercapto-pyridine (HSPy) in EtOH yielded cationic complexes in which HSPy is tautomerized to its 1H-pyridine-thione form as inferred from spectral data. Compound 1 reacts with potassium alkyl-xanthates KS2COR (R = Me, Et, iPr) yielding compounds of the type [CpRu(eta1-S2COR)(PEt3)2], whereas the reaction of 2 and 3 led respectively to the complexes [CpRu(eta2-S2COR)(PMeiPr2)] and [Cp*Ru(eta2-S2COR)(PEt3)], which contain one bidentate xanthate and one phosphine. The X-ray crystal structure of [Cp*Ru(S2COiPr)(PEt3)] was determined. In analogous fashion, the reaction of 1 with sodium diethyldithiocarbamate yielded [CpRu(eta1-S2CNEt2)(PEt3) 2], whereas 2 and 3 afforded the corresponding derivatives [CpRu(eta2-S2CNEt2)(PMeiPr 2)] and [Cp*Ru(eta2-S2CNEt2)(PEt3)].

The success of olefin metathesis has spurred the intense investigation of new catalysts for this transformation. With the development of many different catalysts, however, it becomes increasingly difficult to compare their efficiencies. In this article we introduce a set of six reactions with specific reaction conditions to establish a standard for catalyst comparison in olefin metathesis. The reactions were selected on the basis of their ability to provide a maximum amount of information describing catalyst activity, stability, and selectivity, while being operationally simple. Seven of the most widely used ruthenium-based olefin metathesis catalysts were evaluated with these standard screens. This standard is a useful tool for the comparison and evaluation of new metathesis catalysts.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, category: ruthenium-catalysts

Ruthenium complexes are very useful phosphorescent probes for the visualization of hypoxia. We designed and synthesized three ruthenium complexes possessing bromopyrene, naphthalene, or anthracene units to improve the oxygen response. These ruthenium complexes provided strong phosphorescence under hypoxic conditions, while an increase in oxygen concentration led to a decrease in phosphorescence intensity. Among the ruthenium complexes, that with a bromopyrene unit (Ru-BrPy) had the best properties. This showed good cellular uptake and bright emission in cells, and had the highest sensitivity for molecular oxygen. Thus, Ru-BrPy is a promising candidate as a molecular probe for detecting cellular hypoxia.

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 15746-57-3 is helpful to your research., COA of Formula: C20H16Cl2N4Ru

Reference of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

Two pyridine substituted beta-cyclodextrins have been synthesized and coordinated to the photoactive metal centres, [Ru(ii)(bpy)2] and [Re(i)(CO)3bpy], where bpy is 2,2?-bipyridyl. The photophysical and electrochemical properties of these model complexes have been examined and compared with dinuclear complexes formed when C60 was included between two cyclodextrin cavities of the metallocyclodextrin units. On inclusion of C60, significant quenching of the emission of the luminophores is observed. Concentration and laser power dependence confirm that this quenching is intramolecular. The quenching process is interpreted in terms of a photoinduced electron transfer between the photosensitizer and C60 centre on the basis of spectroscopic and electrochemical evidence. Rate constants of 1.3 ± 0.1 × 108 and 7.0 ± 0.4 × 107 s-1 have been determined for the Ru and Re based complexes, respectively. Significantly, these large rate constants indicate that that there is substantial electronic communication across the cyclodextrin at least for excited state processes.

A much improved synthesis for the carbagerma-closo-dodecaborate anion [GeCB10H11]- is described in the form of [Bu3NH][GeCB10H11] (1). In reactions with transition metal electrophiles, three transition metal complexes {[Bu 3NH][(C6H6)Ru(Cl)2(GeCB 10H11)] (2), [Bu3NH][Cp*Ir(Cl)(GeCB 10H11)2] (3) and [Me3NH][(PPh 3)2Ir(CO)(GeCB10H11)2] (4)} with metal-germanium bonds were synthesized. The carbagermaborate anion, in the form of the salt [Et3NH][GeCB10H11], and the coordination compounds 2-4 were structurally characterized by single-crystal X-ray diffraction. Computations were carried out for the anions in 1-4 to aid NMR assignments. An improved synthesis of carbagerma-closo-dodecaborate is presented. Coordination compounds with this type of germylene ligands are structurally characterized, and the ligand properties are discussed by using the results of quantum chemical calculations. Copyright

A new flexible approach for the stereoselective synthesis of substituted 1H-pyrrol-2(5H)-ones and 3,6-dihydro-1H-pyridin-2-ones has been developed. The general strategy employed the stereoselective reduction of a series of alpha,beta-unsaturated ketones under chelation control to give the corresponding allylic alcohols. Overman rearrangement to install the key C-N bond followed by conversion to either prop-2-enoyl or but-3-enoyl derivatives and a ring closing metathesis reaction gave the target unsaturated gamma- and delta-lactams. The synthetic utility of these compounds as building blocks was demonstrated by the preparation of the N-Boc derivative of (-)-coniine.

An efficient method for the preparation of new alpha-CF3 alpha-amino acid 1,7-enynes that contain electron-donating and electron-withdrawing groups on the triple bond has been developed that proceeds through a Sonogashira-type coupling reaction. The ring-closing enyne methathesis (RCEYM) of the obtained 1,7-enynes with commercially available Grubbs and Hoveyda catalysts provides access to a series of new cyclic alpha-amino acids.
