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, Computed Properties of C12H12Cl4Ru2

Hydrative dimerization and hydration of allenes proceeded in the presence of a ruthenium catalyst and a strong acid such as trifluoroacetic acid. gamma,delta-Unsaturated ketones and methyl ketones were isolated in moderate combined yields. No isomeric compound (isomeric enone) was isolated. Copyright

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.Computed Properties of C12H12Cl4Ru2, you can also check out more blogs about37366-09-9

Half-sandwich ruthenium, rhodium and iridium complexes (1?12) were synthesized with aldoxime (L1), ketoxime (L2) and amidoxime (L3) ligands. Ligands have the general formula [PyC(R)NOH], where R = H (L1), R = CH3 (L2) and R = NH2 (L3). Reaction of [{(arene)MCl2}2] (arene = p-cymene, benzene, Cp*; M = Ru, Rh, Ir) with ligands L1?L3 in 1:2 metal precursor-to-ligand ratio yielded complexes such as [{(arene)MLkappa2 (N?N)Cl}]PF6. All the ligands act as bidentate chelating nitrogen donors in kappa2 (N?N) fashion while forming complexes. In vitro anti-tumour activity of complexes 2 and 10 against HT-29 (human colorectal cancer), BE (human colorectal cancer) and MIA PaCa-2 (human pancreatic cancer) cell lines and non-cancer cell line ARPE-19 (human retinal epithelial cells) revealed a comparable activity although complex 2 demonstrated greater selectivity for MIA PaCa-2 cells than cisplatin. Further studies demonstrated that complexes 3, 6, 9 and 12 induced significant apoptosis in Dalton’s ascites lymphoma (DL) cells. In vivo anti-tumour activity of complex 2 on DL-bearing mice revealed a statistically significant anti-tumour activity (P = 0.0052). Complexes 1?12 exhibit HOMO?LUMO energy gaps from 3.31 to 3.68 eV. Time-dependent density functional theory calculations explain the nature of electronic transitions and were in good agreement with experiments.

Reactions of [RuCl2(eta6-arene)]2 with ammonium salt of dialkyldithiophosphoric acid in 1 : 1 and 1 : 2 stoichiometry readily gave complexes of the type [Ru{SSP(OR)2}(Cl)(eta6-arene)] (arene = benzene, p-cymene; R = Et, nPr, 1Pr, nBu or sBu) and [Ru{SSP(OR)2}2(eta6-arene)] (R = Et; arene = p-cymene). The former complexes, on treatment with NaBPh4 in acetone followed by addition of a neutral donor ligand (L), afforded cationic complexes [Ru{SSP(OEt)2}(eta6-p-cymene)L][BPh4] (L = py, PPh3, (p-FC6H4)3P, AsPh3]. All the complexes were characterized by elemental analysis and NMR (1H, 31P) data. A single crystal X-ray structure determination of [Ru{SSP(OEt)2}(eta6-p-cymene)(PPh3)][BPh4] has established an octahedral configuration around the ruthenium atom. The structure consists of a ruthenium centre bonded to an eta6-p-cymene, a chelated dithiophosphate and a unidentate triphenylphosphine ligand.

Yellow cyclometalatated ruthenium (II) complexes [Ru(o-X-2-py)(MeCN) 4]PF6 (1, X = C6H4 (a) or 4-MeC 6H3 (b)) react readily with 1,10-phenanthroline (LL) in MeCN to give brownish-red species cis-[Ru(o-X-2-py)(LL)(MeCN) 2]PF6 in high yields. The same reaction of the same complexes under the same conditions with 2,2?-bipyridine results in a significant color change from yellow to brownish-orange suggesting a formation of new species. Surprisingly, X-ray structural studies of these two complexes showed that they are structurally indistinguishable from the starting complexes 1. Referred to as complexes 4a,b, the new compounds are slightly more stable in the air though their spectral characteristics in solution are similar to 1a,b. The diffuse reflectance spectroscopy is so far the only technique that indicated differences between 1 and 4.

Electric Literature of 246047-72-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium. In a document type is Article, introducing its new discovery.

A series of Ru-based olefin metathesis catalysts containing N,N?-diamidocarbenes (DACs) were synthesized and studied. X-ray crystallographic analysis revealed that the Ru-Ccarbene distances (1.938(5)-1.984(4) A) measured in the DAC-supported complexes were relatively short, particularly in comparison to the range of Ru-C carbene distances typically observed in analogous N-heterocyclic carbene (NHC) supported complexes (1.96-2.03 A). While the Tolman electronic parameters (TEP) of various DACs (2056-2057 cm-1) were calculated to be similar to that of PCy3 (2056 cm-1), the ring-closing metathesis (RCM) of diethyl diallylmalonate facilitated by DAC-supported Ru complexes proceeded at a relatively slow rate. However, unlike the phosphine-containing complexes, the DAC analogues catalyzed the RCM of diethyl dimethallylmalonate to its respective tetrasubstituted olefin. A series of electrochemical experiments revealed that the Ru complexes bearing a DAC ligand underwent oxidation at significantly higher potentials (DeltaE pa > 0.5 V) than analogous complexes containing phosphines and various N-heterocyclic carbenes (NHCs), including a tetrahydropyrimidinylidene, a saturated and strongly donating NHC analogue of the DAC. The relative catalytic activities observed were attributed to the steric properties of the aforementioned ligands.

A range of TsDPEN catalysts containing heterocyclic groups on the amine nitrogen atom were prepared and evaluated in the asymmetric transfer hydrogenation of ketones. Bidentate and tridentate ligands demonstrated a mutual exclusivity directly related to their function as catalysts. A broad series of ketones were reduced with these new catalysts, permitting the ready identification of an optimal catalyst for each substrate and revealing the subtle effects that changes to nearby donor groups can exhibit.
