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, Recommanded Product: Dichloro(benzene)ruthenium(II) dimer.

A diastereomerically mixed complex [Ru{(S)-phgly}2{(¡À)- biphep}] is readily prepared from achiral diphosphine BIPHEP in two steps. These diastereomers are then separated by silica gel column chromatography. A 61:39 equilibrium mixture of [Ru{(S)-phgly}2{(S)-biphep}] and [Ru{(S)-phgly}2{(R)-biphep}] with Li2CO3 is used to catalyze cyanosilylation of benzaldehyde to afford the R cyanated product in 92% ee. The enantioselectivity is just slightly lower than that by using the pure [Ru{(S)-phgly}2{(S)-biphep}]/Li2CO 3 catalyst system of 96%. The high enantioselective ability of the diastereomerically mixed catalyst is revealed through a series of kinetic experiments in which the highly enantioselective [Ru{(S)-phgly} 2{(S)-biphep}]/Li2CO3 system is shown to catalyze the reaction 16.8 times faster than the less selective [Ru{(S)-phgly}2{(R)-biphep}]/Li2CO3 system, affording the product in 2.6% ee. An equation is derived to approximate the relationship between the diastereomeric ratio of the catalyst and the ee value of the product.

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

The quinoline moieties of the metal-bound eta2-1,1?-biisoquinoline ligand of (eta6-benzene)(delta/ lambda-1,1?-biisoquinoline)halometal(II) hexafluorophosphate (metal = ruthenium, osmium; halo = chloro, iodo; 1(M = Ru, Os; X = Cl, I)) are stereotopic. The rates of atropisomerization of the delta/lambda-1,1?-biisoquinoline ligand, measured by spin-labeling NMR methods, indicate the energy barrier is higher for 1(Ru) than 1(Os); e.g., DeltaH?[1(M = Ru, X = Cl)] = 77.3(2) and DeltaH?[1(M = Os, X = Cl)] = 71.2(2) kJ mol-1. Since the crystal structures of 1(M = Ru, X = Cl) and 1(M = Os, X = Cl) reveal comparable metric parameters, steric factors associated with atropisomerization of the 1,1?-biisoquinoline ligand, essentially the deformation of the 1,1?-binaphthylene skeleton that is necessary to pass H8 and H8? past one another, are presumably equivalent for the Ru and Os derivatives. Assuming that normal bond energies are greater for the third-row transition metal than for second-row transition metals, we conclude the difference in reactivity can be attributed to electronic factors – the sigma-donor orbitals and pi-acceptor orbitals of the 1,1-biisoquinoline ligand are misdirected in the ground state but redirected in the syn transition state of atropisomerization. Thus, an inverse relationship between the kinetic and thermodynamic stabilities of 1 is observed for the misdirected ? [directed]? ? misdirected (MDM) isomerization of 1 (the more thermodynamically stable bond is more reactive). Atropisomerization of 1 represents only the second example of such an inverse free-energy relationship for a thermodynamically controlled reaction, and it contrasts with the regular relationship that has been found for the atropisomerization of related directed ? [misdirected]? ? directed (DMD) systems.

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

Synthesis, characterization, DNA and protein binding as well as anticancer activity of the organometallic complexes [(eta6-C6H6)RuCl(APBI)]Cl (1), [(eta6-p-MeC6H4Pri)RuCl(APBI)]Cl (2), [(eta6-C6Me6)RuCl(APBI)]Cl (3), [(eta5-C5Me5)RhCl(APBI)]Cl·H2O (4) and [(eta5-C5Me5)IrCl(APBI)]Cl·H2O (5) containing 2-aminophenyl benzimidazole (APBI) have been described. The complexes 1-5 exhibited strong DNA, protein binding and anticancer activity against cervical cancer (SiHa) cell line. Their binding with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) have been examined by absorption and emission spectral studies. Strong interactions between complexes and CT-DNA have been affirmed by absorption spectral and EthBr displacement studies, while interaction with BSA via static quenching explored by fluorescence titration, synchronous and 3D fluorescence spectroscopy. The interactions between 1-5 and DNA has also been scrutinized by 1H NMR spectral studies using guanosine as a model for DNA. These results have been supported by DFT calculations and molecular docking studies. Cytotoxicity, apoptosis and in vitro anticancer activity of 1-5 toward SiHa cell line have been investigated by MTT assay and acridine (AO)/ethidium bromide (EthBr) fluorescence staining. Overall results revealed that DNA and protein binding, as well as anticancer activity of 1-5 follows the order as 5 > 3 > 2 > 1 > 4.

A synthetic procedure is described that provides access to [Ru(bpy) 3]2+ analogues in which one bpy ligand is replaced by a C,N-bidentate-coordinating carbene-benzimidazole ligand (bpy = 2,2?-bipyridine). These new complexes were prepared by first installing the chelating carbene ligand onto a Ru(cymene) platform and subsequent ligand substitution using bpy or terpy (terpy = 2:2?,6?:2??- terpyridine). The carbene ligand significantly affects the optical properties of the complex and lowers the ruthenium(II) oxidation potential substantially. Such modifications may be advantageous for the development of new classes of photosensitizer materials.

The catalytic hydrogenation of cyclohexene and 1-methylcyclohexene is investigated experimentally and by means of density functional theory (DFT) computations using novel ruthenium XantphosPh (4,5-bis(diphenylphosphino)-9,9-dimethylxanthene) and XantphosCy (4,5-bis(dicyclohexylphosphino)-9,9-dimethylxanthene) precatalysts [Ru(XantphosPh)(PhCO2)(Cl)] (1) and [Ru(XantphosCy)(PhCO2)(Cl)] (2), the synthesis, characterization, and crystal structures of which are reported. The intention of this work is to (i) understand the reaction mechanisms on the microscopic level and (ii) compare experimentally observed activation barriers with computed barriers. The Gibbs free activation energy DeltaG? was obtained experimentally with precatalyst 1 from Eyring plots for the hydrogenation of cyclohexene (DeltaG? = 17.2 ± 1.0 kcal/mol) and 1-methylcyclohexene (DeltaG? = 18.8 ± 2.4 kcal/mol), while the Gibbs free activation energy DeltaG? for the hydrogenation of cyclohexene with precatalyst 2 was determined to be 21.1 ± 2.3 kcal/mol. Plausible activation pathways and catalytic cycles were computed in the gas phase (M06-L/def2-SVP). A variety of popular density functionals (omegaB97X-D, LC-omegaPBE, CAM-B3LYP, B3LYP, B97-D3BJ, B3LYP-D3, BP86-D3, PBE0-D3, M06-L, MN12-L) were used to reoptimize the turnover determining states in the solvent phase (DF/def2-TZVP; IEF-PCM and/or SMD) to investigate how well the experimentally obtained activation barriers can be reproduced by the calculations. The density functionals B97-D3BJ, MN12-L, M06-L, B3LYP-D3, and CAM-B3LYP reproduce the experimentally observed activation barriers for both olefins very well with very small (0.1 kcal/mol) to moderate (3.0 kcal/mol) mean deviations from the experimental values indicating for the field of hydrogenation catalysis most of these functionals to be useful for in silico catalyst design prior to experimental work.

Reference of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.

Arene ruthenium(II) complexes containing bis(pyrazolyl)methane ligands have been prepared by reacting the ligands L? (L? in general; specifically L1 = H2C(pz)2, L2 = H2C(pzMe2)2, L3 = H2C(pz4Me)2, L4 = Me2C(pz)2 and L5 = Et 2C(pz)2 where pz = pyrazole) with [(arene)RuCl(mu-Cl)] 2 dimers (arene = p-cymene or benzene). When the reaction was carried out in methanol solution, complexes of the type [(arene)Ru(L?)Cl]Cl were obtained. When L1, L2, L3, and L5 ligands reacted with excess [(arene)RuCl(mu-Cl)]2, [(arene)Ru(L?)Cl][(arene)RuCl3] species have been obtained, whereas by using the L4 ligand under the same reaction conditions the unexpected [(p-cymene)Ru(pzH)2Cl]Cl complex was recovered. The reaction of 1 equiv of [(p-cymene)Ru(L?)Cl]Cl and of [(p-cymene)Ru(pzH) 2Cl]Cl with 1 equiv of AgX (X = O3SCF3 or BF4) in methanol afforded the complexes [(p-cymene)Ru(L?)Cl] (O3SCF3) (L? = L1 or L2) and [(p-cymene)Ru(pzH)2Cl]BF4, respectively. [(p-cymene)Ru(L1)(H2O)][PF6]2 formed when [(p-cymene)Ru(L1)Cl]Cl reacts with an excess of AgPF 6. The solid-state structures of the three complexes, [(p-cymene)Ru{H2C(pz)2}Cl]Cl, [(p-cymene)Ru{H 2Cpz4Me)2}Cl]Cl, and [(p-cymene)Ru{H 2C(pz)2}Cl](O3SCF3), were determined by X-ray crystallographic studies. The interionic structure of [(p-cymene)Ru(L1)Cl](O3SCF3) and [(p-cymene)Ru(L?)Cl][(p-cymene)RuCl3] (L? = L1 or L2) was investigated through an integrated experimental approach based on NOE and pulsed field gradient spin-echo (PGSE) NMR experiments in CD2Cl2 as a function of the concentration. PGSE NMR measurements indicate the predominance of ion pairs in solution. NOE measurements suggest that (O3SCF3)- approaches the cation orienting itself toward the CH2 moiety of the L 1 (H2C(pz)2) ligand as found in the solid state. Selected Ru species have been preliminarily investigated as catalysts toward styrene oxidation by dihydrogen peroxide, [(p-cymene)Ru(L 1)(H2O)][PF6]2 being the most active species.

Reactions of [{Ru(eta3:eta3-C10H 16)(mu-Cl)Cl}2] with 1,4-dicyanobenzene (DCB) or 1,4-piperazinedicarbonitrile (PPz) in dichloromethane in 1:2 and 1:1 molar ratio gives mononuclear complex [Ru(eta3:eta3-C10H16)Cl 2(L)] and binuclear complex [{Ru(eta3:eta3-C10H16)Cl 2}2(mu-L)]. However, its reaction with 1,4-dicyanotrans-2-butene (DCBT) gives only a binuclear complex [{Ru(eta3:eta3-C10H16)Cl 2}2(mu-DCBT)] and with 1-piperidinecarbonitrile (PPd), a mononuclear complex [Ru(eta3:eta3-C10H16)Cl 2(L)]. The mononuclear complexes resulting from the reaction of [{Ru(eta3:eta3-C10H 16)(mu-Cl)Cl}2] with DCB or PPz possesses pendant nitrile group. Nucleophilicity of the pendant nitrile group in these complexes have been employed in the synthesis of binuclear mixed valence-bridged complexes, in which, the respective metal centers are bridged by DCB or PPz ligand. The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H NMR and 13C NMR spectra).

Only four types of dimeric precursors [RuCl2(eta6-arene)]2 for the synthesis of Noyori’s half sandwich diamine catalysts [RuCl(TsDPEN)(eta6-arene)] are commercially available, yet so far no study has tried to systematically evaluate how these systems perform during the asymmetric transfer hydrogenation of various 3,4-dihydroisoquinolines (i.e., the typical substrates for Noyori asymmetric transfer hydrogenation benchmarking). Experiments combined with molecular modeling allowed us to assess their properties and formulate a hypothesis clarifying the difference in enantioselectivity of these systems.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C12H12Cl4Ru2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.
