A dinuclear Schiff base RuII complex derived from 5-chlorosalicylaldehyde and 2-aminopyridine was synthesized. The structure of the compound was analyzed by mass spectrometry as well as IR, UV/Vis, and 1H NMR spectroscopy, along with chemical analysis,as well as magnetic, cyclovoltammetric and conductivity measurements. Two RuII atoms are octahedrally coordinated by azomethine and pyridine nitrogen atoms from two tridentate monobasic Schiff bases and bridging phenol oxygen atoms. The formula of the complex is [Ru2L2Cl2(Et2NH)(H2O)] [L = N-(2-pyridyl)-5-chlorosalicylideneimine and Et2NH = isodiethylamine]. The RuII atoms in the dinuclear neutral complex species have different coordination environments, RuN3O2Cl and RuN2O3Cl. Interaction with CT DNA showed moderate hydrophobic binding. The compound demonstrates strong activity against methicillin-resistant Staphylococcus aureus, methicillin-sensitive Staphylococcus aureus, and especially Enterococcus faecalis. Microbiological tests showed significant inhibition of growth and ability to kill pathogens, similar or even improved compared to reference antibiotics vancomycin.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article£¬once mentioned of 10049-08-8, Computed Properties of Cl3Ru

The polyoxometalate ions PMo12O403-, PW12O403-, and SiW12O404- are incorporated in polymeric ruthenium(II)(vinyl)bipyridine (poly-Ru(vbpy)32+) films from agueous and dioxane-water electrolytes.Despite their large mass ions exist as freely diffusing species that compensate for up to 30percent of the charge in poly-Ru(vbpy)32+.An investigation of the effect of environmental conditions on electrochemical behavior reveals that the first two one-electron reduction waves of SiW12O404- coalesce into a single two-electron reaction and those of PW12O403- shift significantly in potential upon a change from pure aqueous to 50(v/v)percent dioxane/water solvent.The observation is attributed to destabilization of the one-electron reaction products as the solvent is enriched is dioxane.Incorporation of polyoxometalates is protonated poly(vinyl)pyridine and poly-Ru(vbpy)32+ films from dioxane-water solvent results in differences in electrochemical behavior.Polyoxometalate anions incorporated in poly-Ru(vbpy)32+ films catalyze the electrochemical reduction of hydrogen ion.Key words: polyoxometalate, electrochemistry, poly-Ru(vbpy)32+, electrocatalysis, immobilization.

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.

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, SDS of cas: 32993-05-8

This work reports the first method for the synthesis of alpha-hydroxyphosphonates from aldehydes catalyzed by cyclopentadienyl ruthenium(II) complexes. The best results were obtained using the system HP(O)(OEt)2/[RuClCp(PPh3)2] (5 mol%), affording the alpha-hydroxyphosphonates in good to excellent yields with high chemoselectivity. The catalyst [RuClCp(PPh3)2] can be used for at least 12 catalytic cycles with excellent activity and the reactions were carried out under solvent free conditions. DFT calculations were performed to rationalize the mechanism showing that the barriers associated with the H-phosphonate tautomer, HP(O)(OR)2 are unrealistically high. This led us to propose that the catalyst promotes the tautomerization towards phosphite, P(OH)(OR)2, via P-atom coordination, which accounts for the observed reactivity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 32993-05-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 32993-05-8, in my other articles.

Treatment of hexane-2,5-dione bis(thiosemicarbazones) ([CH3?C{= N?NH?C(=S)?NHR}?CH2]2, R = H, L1H2; CH3, L2H2?Me; CH2CH3, L3H2?Et; C6H5, L4H2?Ph) with nickel(II) acetate hydrate in refluxing ethanol gave a series of NiIIN2S2 metalloligands [Ni(L-R)] for the generation of hetero-bimetallic complexes. The reaction of equal mole each of [Ni(L1)], [Ni(L2?Me)], [Ni(L3?Et)], or [Ni(L4?Ph)] with [RuCl2(dmso)4] (dmso = dimethyl sulfoxide) at reflux resulted in isolation of neutral dinuclear ruthenium-nickel complexes [RuCl2{(Ni(L1)}(dmso)2] (1), [RuCl2{(Ni(L2?Me)}(dmso)2] (2), [RuCl2{(Ni(L3?Et)}(dmso)2] (3), and [RuCl2{(Ni(L4?Ph)}(dmso)2] (4). Interaction of [Ni(L-R)] with [CpRu(PPh3)2Cl] (Cp? = cyclopentadienyl) at room temperature led to formation of cationic dinuclear organoruthenium-nickel complexes [CpRu{(Ni(L1)}(PPh3)]Cl (5), [CpRu{(Ni(L2?Me)}(PPh3)]Cl (6), [CpRu{(Ni(L3?Et}(PPh3)]Cl (7), and [CpRu{(Ni(L4?Ph}(PPh3)]Cl (8). New bimetallic ruthenium-nickel complexes 1?8 have been characterized spectroscopically, of which molecular structures of three complexes [RuCl2{(Ni(L2?Me)}(dmso)2]¡¤CH2Cl2 (2¡¤CH2Cl2), [CpRu{(Ni(L2?Me)}(PPh3)]Cl?EtOH (6?EtOH), and [CpRu{(Ni(L3?Et}(PPh3)]Cl (7?H2O) have been established by single-crystal X-ray crystallography. Their catalytic activities for the acetalation of benzaldehyde in the presence of molecular H2 have been also investigated in this paper.

An efficient hydrogen bonding-guided ring-closing metathesis (RCM) reaction of sterically demanding homoallyl 2-(hydroxymethyl)acrylates catalyzed by the Hoveyda-Grubbs 2nd generation catalyst was developed and the reaction mechanism was explored. Adding a substituent to the hydroxymethyl group in this scaffold resulted in a class of challenging RCM substrates, although usable yields could be obtained. However, substrates bearing a 1-oxygenated alkyl group on the homoallylic carbon gave excellent RCM yields, providing a practical solution. Experimental and computational evidence indicated an unusual directing effect of OH?Cl hydrogen bonding between the substrate and Ru catalyst, which guides Ru to interact with the electron-deficient, more hindered acrylic C=C bond and thus triggers the RCM process.

The reaction velocity follows first-order kinetics with respect to the organic substrate at its lower concentrations and tends to become zero order at higher concentrations in the presence of ruthenium(III). The reaction follows first-order kinetics with respect to ruthenium(III) chloride. On the other hand, the rate of the reaction is directly proportional to the lower concentrations of ruthenium(VIII), but at higher catalyst concentrations the calalytic behavior is decreased. The reaction rate shows direct proportionality with respect to the organic substrate in the presence of ruthenium(VIII).
