The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, Product Details of 37366-09-9

New series of mono and binuclear arene ruthenium complexes [{(eta6-arene)RuCl(L)}]+ and [{(eta6-arene)RuCl}2(mu-L)2] 2+ (arene=benzene, p-cymene or hexamethylbenzene), {L=pyridine-2-carbaldehyde azine (paa), p-phenylene-bis(picoline)-aldimine (pbp) and p-bi-phenylene-bis (picoline)-aldimine (bbp)} are reported. The complexes have been fully characterized and molecular structure of the representative mononuclear complex [(eta6-C6Me6) RuCl(paa)]BF4 (1), binuclear complexes [{(eta6-C10H14)RuCl}2 (mu-paa)](BF4)2 (3) and [{(eta6-C10H14) RuCl}2(mu-pbp)](BF4)2 (6) have been determined by single crystal X-ray diffraction analyses. Single crystal X-ray structure determination revealed that in the binuclear complexes the [(eta6-C10H14) RuCl]+ units are trans disposed. Further, the crystal packing in the complexes 1, 3 and 6 is stabilized by C-H?X type (X=Cl, F) inter, intramolecular hydrogen bonding and pi-pi stacking (3). To explore the ambiguous nature of the bonding between pyridine-2-carbaldehyde azine (paa) with ruthenium containing units [(eta6-arene)RuCl]+, DFT/B3LYP calculations have been performed on the complexes [(eta6-arene) RuCl(paa)]+ (arene=C6H6, I; C6Me6, II; C10H14, III).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 37366-09-9, you can also check out more blogs about37366-09-9

10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 10049-08-8, Computed Properties of Cl3Ru

For Ru and Ir oxide electrodes sintered at different temperatures, in this work, surface resistivity, X-ray photoelectron spectroscopy, electrode lifetime, voltammetric charge capacity, and total organic carbon of 4-chlorophenol (4CP) decomposition at the electrodes were measured, and then intermediates during the electrolysis were identified by gas chromatography-mass spectroscopy to predict the destruction path of 4CP at the electrodes. A sintering temperature of around 650C, rather than 400-550C suggested in the literature for the fabrication of Ru and Ir oxide electrode, showed the highest organic destruction yield. The sintering temperature strongly affected the electrode lifetime as well. During the high temperature sintering, increase of the sintering time caused the oxidation of the Ti substrate to result in the increase of oxide weight of the electrode and the solid diffusion of the generated TiO2 to the electrode surface, which decreased the electrode activity so that the organic destruction yield went down slowly. The destruction path of 4CP at a high temperature-sintered electrode was suggested to be different from that at a low temperature-sintered one. The Ru oxide electrode sintered at 450C generated several complicated aliphatic intermediates.

Reference of 172222-30-9, An article , which mentions 172222-30-9, molecular formula is C43H72Cl2P2Ru. The compound – Benzylidenebis(tricyclohexylphosphine)dichlororuthenium played an important role in people’s production and life.

Addition of organometallic reagents to chiral oxime ethers 1 derived from an unsaturated aldehyde, or addition of an alkene containing organometallic to chiral aldoxime ethers 2 results in highly stereoselective formation of the hydroxylamines 6. N-Allylation gives the dienes 7 which undergo ring-closing metathesis (RCM) reaction to give the 5-, 6-, and 7-membered nitrogen heterocycles 8. Likewise, the benzyl carbamates 9, also prepared by stereoselective addition to oxime ethers, were converted into dienes 10, which underwent RCM to give the 5- to 8-membered azacycles 11. The oxime addition-RCM protocol is thus a versatile method for the asymmetric synthesis of nitrogen heterocycles, further exemplified by the conversion of the unsaturated heterocycles into chiral piperidines, including the alkaloid (-)-coniine.

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

The new potentially bidentate pyrazole-phosphinite ligands [(3,5-dimethyl-1H-pyrazol-1-yl)methyl diphenylphosphinite] (L1) and [2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl diphenylphosphinite] (L2) were synthesised and characterised. The reaction of L1 and L2 with the dimeric complexes [Ru(eta6-arene)Cl2] 2 (arene = p-cymene, benzene) led to the formation of neutral complexes [Ru(eta6-arene)Cl2(L)] (L = L1, L2) where the pyrazole-phosphinite ligand is kappa1-P coordinated to the metal. The subsequent reaction of these complexes with NaBPh4 or NaBF4 produced the [Ru(eta6-p- cymene)Cl(L2)][BPh4] and [Ru(eta6-benzene) Cl(L2)][BF4] compounds which contain the pyrazole-phosphinite ligand kappa2-P,N bonded to ruthenium. All the complexes were fully characterised by analytical and spectroscopic methods. The structure of the complex [Ru(eta6-p-cymene)Cl(L 2)][BPh4] was also determined by a X-ray single crystal diffraction study.

Several new C-H-activated ruthenium catalysts for Z-selective olefin metathesis have been synthesized. Both the carboxylate ligand and the aryl group of the N-heterocyclic carbene have been altered and the resulting catalysts evaluated using a range of metathesis reactions. Substitution of bidentate with monodentate X-type ligands led to a severe attenuation of metathesis activity and selectivity, while minor differences were observed between bidentate ligands within the same family (e.g., carboxylates). The use of nitrato-type ligands in place of carboxylates afforded a significant improvement in metathesis activity and selectivity. With these catalysts, turnover numbers approaching 1000 were possible for a variety of cross-metathesis reactions, including the synthesis of industrially relevant products.

One PPh3 group of CpRu(PPh3)2Cl is easily substituted by PPh2H to give the asymmetrical complex CpRu(PPh3)(PPh2H)Cl (1) in a very good yield. Attempts to form the lambda4-phosphanediyl complex CpRu (PPh3)=PPh2 (1?) by selective dehydrohalogenation of 1 failed. However, by using one equivalent of the chelating diphosphine dppa two PPh3 ligands are substituted to yield CpRu(dppa)Cl (2). With an excess of dppa the reaction yielded the N-iminophosphoranyl-substituted dppa complex CpRu{(PPh2)2NPPh2=NH}Cl (3) and PPh2H. 1H, 13C{1H} and 31P{1H} NMR, IR and mass spectra of 1-3 are given.

A quite general approach for the preparation of eta5- and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl] 2 (arene = C6H6, C10H14 and C6Me6) and eta5- pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5- C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) reacts with two equivalents of the ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) in presence of NH 4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(L1)Cl]PF6 {arene = C6H6 (1), C10H14 (2) and C 6Me6 (3)}, [(eta6-arene)Ru(L 2)Cl]PF6 {arene = C6H6 (4), C 10H14 (5) and C6Me6 (6)}, and [(eta5-C5Me5)M(L1)Cl]PF 6 {M = Rh (7), Ir (8)} and [(eta5-C5Me 5)M(L2)Cl]PF6 {M = Rh (9), Ir (10)}. However the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3) 2Cl], [(eta5-C5H5)Os(PPh 3)2Br], [(eta5-C5Me 5)Ru(PPh3)2Cl] and [(eta5-C 9H7)Ru(PPh3)2Cl] complexes react in presence of one equivalent of ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) and one equivalent of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(L 1)]PF6 (11), [(eta5-C5H 5)Os(PPh3)(L1)]PF6 (12), [(eta5-C5Me5)Ru(PPh3)(L 1)]PF6 (13) and [(eta5-C9H 7)Ru(PPh3)(L1)]PF6 (14) and [(eta5-C5H5)Ru(PPh3)(L 2)]PF6 (15), [(eta5-C5H 5)Os(PPh3)(L2)]PF6 (16), [(eta5-C5Me5)Ru(PPh3)(L 2)]PF6 (17) and [(eta5-C9H 7)Ru(PPh3)(L2)]PF6 (18) respectively. These compounds have been systematically characterized by IR, NMR and mass spectrometry. The molecular structures of 2, 4 and 15 have been established by single crystal X-ray diffraction study and some of the representative complexes have also been studied by UV-visible spectroscopy. The crystal packing diagram of complex 4 reveals that the cation [(eta6-C6H6)Ru(L2)Cl]+ is engaged in non-covalent interaction. This compound gives rise to a 1D helical architecture along the ‘a’ axis via intermolecular NH?Cl hydrogen bonds.
