The cyclopentadienyl (Cp) group is a ligand of great importance for many transition-metal complexes used in catalysis. Cationic CpRuII complexes with three free coordination sites are highly versatile catalysts for many atom-economic transformations. We report the synthesis of a family of CpxRuII complexes with chiral Cp ligands keeping the maximum number of available coordination sites. The cationic members are efficient and selective catalysts for yne-enone cyclizations via formal hetero-Diels-Alder reactions. The transformation proceeds in <1 h at -20 C and provides pyrans in up to 99:1 er. Unsaturated ester or Weinreb-amide substrates directly yield the iridoid skeleton. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C12H12Cl4Ru2.

2,2?-Dipyridyl-N-arylimines L (L1 = 2,4,6-trimethyl(di-2- pyridylmethylene)aniline, L2 = 2,6-diisopropyl(di-2-pyridylmethylene) aniline) react with arene ruthenium dichloride dimer in methanol to give cationic arene ruthenium complexes of the general type [(arene) Ru(eta2-N,N-L)Cl]+ (arene = C6H6, p-MeC6H4Pri). Two coordination modes of the chelating ligands N,N-L are observed. In the major isomer, the ketimine nitrogen atom and one of the two pyridine nitrogen atoms are coordinated to ruthenium, while in the minor isomer the two pyridine nitrogen atoms coordinate to the metal center. In the case of L1, the minor isomer of the p-cymene ruthenium chloro complex could be isolated as the tetrafluoroborate salt and characterized by single crystal X-ray analysis. The molecular structure of the major isomer was determined by X-ray crystallography in the case of the tetraphenylborate salt of the benzene ruthenium chloro derivative. In both structures, the ruthenium atom shows the expected pseudo-tetrahedral coordination geometry.

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. In a Article，once mentioned of 246047-72-3, Formula: C46H65Cl2N2PRu

We report the first use of solution-phase halogen bonding to control and facilitate the assembly of an interlocked structure through the bromide anion-templated formation of a rotaxane based upon an iodotriazolium axle. The incorporation of a halogen atom into the rotaxane host cavity dramatically improves the anion-recognition capabilities of the interlocked receptor, giving unusual iodide selectivity in a competitive aqueous medium.

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.Formula: C46H65Cl2N2PRu, you can also check out more blogs about246047-72-3

The synthesis of 2-substituted pyridine?pyrimidine ligands and their complexation with arene ruthenium(II) chloride moieties is reported. Depending on the electronic and steric influences of the ligand, the catalysts undergo CH activation by roll-over cyclometalation. This process opens up the route to the catalytic transfer hydrogenation of ketones with isopropanol as the hydrogen source under base-free and mild conditions. Barriers related to the roll-over cyclometalation process can be determined experimentally by collision-induced dissociation ESI mass spectrometry. They are supported by DFT calculations and allow the classification of the ligands according to their electronic and steric properties, which is also in accordance with critical bond parameters derived from X-ray structure data. DFT calculations furthermore reveal that the formation of a ruthenium(II) hydrido species is plausible through beta-hydride elimination from isopropanol.

We report herein the preparation and characterization of dinuclear complexes with the bridging ligand 1,10-phenanthroline-5,6-dithiolate (phendt2-) bearing Ru(bpy)2 or Ir(ppy)2 at the diimine moiety and Ni(dppe), Ni(dppf), CoCp, RhCp?, and Ru(p-Me-iPr-benzene) at the dithiolate unit. In comparison with the mononuclear precursors used in the synthesis, all dinuclear complexes were characterized by absorption and photoluminescence spectroscopy as well as cyclic voltammetry. Because of the beneficial spectral and electrochemical properties of the Ir/Co complex for a light-driven charge separation, this complex was investigated in detail by time-resolved luminescence {nanosecond (ns)-resolution} and transient absorption spectroscopy {femtosecond (fs)-resolution}. All measurements supported by DFT calculations show that the observed effective luminescence quenching by the dithiolate coordinated metal is caused by an ultrafast singlet-singlet Dexter energy transfer.

We have developed a simple and straightforward procedure for the enantioselective preparation of densely substituted bicyclic and tricyclic nitrogen heterocycles using conveniently substituted enantiopure pyrrolidines as common synthetic intermediates, which are easily accessible by our recently developed organocatalytic enantioselective [3+2] cycloaddition of alpha,beta-unsaturated aldehydes and azomethine ylides. The designed synthetic pathway makes use of a ring-closing metathesis reaction for building up the pyrrolizidine and indolizidine skeletons, while the access to the hexahydrocyclopenta[a]pyrrolizine structure has been carried out relying on a fully diastereoselective intramolecular Pauson-Khand reaction.

The design and synthesis of ruthenium tris-diimine photosensitizers appropriately functionalized to be (i) anchored onto transparent conductive oxides (TCO) and (ii) covalently coupled with a water-splitting catalyst represents an important target for solar fuel production in dye-sensitized photoelectrochemical cells (DS-PECs). In this study, two different synthetic routes to prepare heteroleptic [Ru(4,4?-(CH2PO3Et2)2-bpy)2(N^N)](PF6)2 complexes are evaluated, the scope and limitations of the organometallic pathway involving half-sandwich eta6-arene ruthenium complexes as synthetic intermediates being especially studied. The spectroscopic and electrochemical characterization of a series of novel structures varying by the nature of the third diimine N^N ligand is reported.

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 37366-09-9 is helpful to your research., SDS of cas: 37366-09-9

In an article, published in an article, once mentioned the application of 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II),molecular formula is C46H45ClP2Ru, is a conventional compound. this article was the specific content is as follows.Application In Synthesis of Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II)

Trichlorostannyl complexes [Ru(SnCl3) (Cp?)L] (2a-c) were prepared by treatment of optically active half-sandwich chlorocomplexes [RuCl(Cp?)L] (1a-c) with an excess of SnCl2.2H2O in ethanol. Treatment of trichlorostannyl complexes 2a-c with NaBH4 afforded trihydridostannyl derivatives [Ru(SnH3) (Cp?)L] (3a-c) in moderated yields. Treatment of 2a-c with MgBrMe gave the trimethylstannyl complexes Ru(SnMe3) (Cp?)L (4a-c). Alkynylstannyl derivatives [Ru{Sn(C?CPh)3}(Cp?)L] (5a-c) were prepared by treatment of trichlorostannyl compounds 2a-c with an excess of LiC?CPh in thf. All the complexes present optical activity. The complexes were characterized spectroscopically and by X-ray crystal structure determination of [RuCl(eta5-C5Me5)L] (1b), [Ru(SnCl3) (eta5-C5Me5)L] (2b), and [Ru(SnCl3) (eta5-C9H7)L] (2c). The influence of different ligands on the Ru?P interaction in several complexes 1a-c, 2a-c and 3a-c was evaluated by DFT calculations. These calculations indicate that [SnCl3]- has a stronger stabilization effect than [Cl]- and the same occurs between ?C9H7 and ?C5Me5. These relative stabilities combined with the distortion energies of the fragments produce a stabilizing effect in the Ru?P bonds of complex 2c that is twice as strong as in the 1b complex.

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. 10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article，once mentioned of 10049-08-8, COA of Formula: Cl3Ru

The structure of oxide layers of the RuO2-IrO2/Ti electrode system and the thermal decomposition processes of RuCl3 and IrCl3 to form their respective oxides have been mainly analyzed by EXAFS (extended X-ray absorption fine structure) and XRD (X-ray diffraction). Upon heating of the respective chlorides in air, both chlorides convert into their respective oxides. The coordination numbers of the oxide ions around both the ruthenium and iridium ions increased with an increase in the calcination temperature and attained 6, which is the theoretical value of the standard samples of rutile RuO2 and IrO2. The changes in the coordination number with respect to the calcination temperature were accompanied by changes in the lattice constants of these oxides. This suggests that the deviation of these parameters from the standard sample is caused by the lattice defects of the oxide ions. A dependence of the radial distribution functions of EXAFS on the composition of the RuO2-IrO2/Ti electrode system showed that RuO2 forms a solid solution with IrO2 for the binary oxide electrode system.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: Cl3Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10049-08-8, in my other articles.
