Mechanism of Ru(III) catalysis in N-bromoacetamide oxidation of some glycols in perchloric acid media

The kinetics of ruthenium(III) chloride catalysis in the oxidation of diethylene glycol (DG) and methyl diethylene glycol (MDG) by N-bromoacetamide (NBA) in perchloric acid media are reported. The reactions follow identical kinetics, showing zero-order dependence on NBA, but first-order on each of H+, Ru(III) and Cl- ions. The first-order kinetics with respect to glycol at low concentrations shifts to zero-order at higher concentrations. A negative effect of ionic strength is observed, while successive addition of acetamide, D2O and mercuric acetate shows zero effect on the reaction rate.

Selective formation of a coordinatively unsaturated metal complex at a surface: A SiO2-immobilized, three-coordinate ruthenium catalyst for alkene epoxidation

(Chemical Equation Presented) Unsaturated but air-stable: A three-coordinate Ru complex, 2, highly active for alkene epoxidation and recyclable in air, was prepared on SiO2 by exploiting the exothermic reaction between O2 and isobutyraldehyde (IBA) to eliminate a p-cymene ligand from a coordinatively saturated precursor 1 (Ru red, Cl dark blue, N green, S yellow, O blue, C gray, H white). In contrast, direct activation with O2 alone was calculated to be endothermic.

Kinetic and mechanistic study of Br(V) oxidation of glycolic acid catalysed by aquochlororuthenium(III) complex at different acid strengths: Evaluation of individual rate constants and thermodynamic parameters

Oxidation of glycolic acid (GA) by bromate in the presence of perchloric acid at moderate and low concentrations is catalysed by aquochlororuthenium(III) complex. The reactions at moderate and low acid strengths exhibit different kinetic behaviour on account of existence of catalyst in different forms. In moderate acid solutions, the mechanism proposed involves the oxidation of Ru(III) to Ru(V) by oxidant which in turn forms a reversible complex with substrate in the ratio of 1:2. The decomposition of the complex thus formed, into products is the slow rate determining step. At lower [acid], the mechanism is visualised as the formation of reversible complex between GA and catalyst preceding the formation of an intermediate with the oxidant in a slow-step. The decomposition of the intermediate into products is assumed to be the fast step. The rate constants involved in all individual steps of the reactions are evaluated along with their activation parameters and discussed.

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.Recommanded Product: 10049-08-8, you can also check out more blogs about10049-08-8

Electrophoretic deposition (EPD) of hydrous ruthenium oxides with PTFE and their supercapacitor performances

The effect of PTFE addition was investigated for the electrophoretic deposition (EPD) of hydrous ruthenium oxide electrodes. Mechanical stability of electrode layers, together with deposition yield, was enhanced by using hydrous ruthenium oxide/PTFE dispersions. High supercapacitor performance was obtained for the electrodes prepared with 2% PTFE and 10% water. When PTFE content was higher, the rate capability became poor with low electronic conductivity; higher water content than 10% resulted in non-uniform depositions with poor cycleability and power capability. When electrodes were heat treated at 200 C for 10 h, the specific energy was as high as 17.6 Wh/kg based on single electrode (at 200 W/kg); while utilizable energy was lower with heat treatment time of 1 and 50 h, due to the high resistance and gradual crystallization, respectively. With PTFE addition and heat treatment at 200 C for 10 h, the specific capacitance was increased by 31% (460 ? 599 F/g at ca. 0.6 mg/cm2) at 10 mV/s, and the deposition weight was increased up to 1.7 mg/cm2 with initial capacitance of 350 F/g.

Trivalent iron and ruthenium complexes with a redox noninnocent (2-Mercaptophenylimino)-methyl-4,6-di-tert-butylphenolate(2-) Ligand

The 3,5-di-tert-butyl substituted N-(salicylidene)-o-mercaptoaniline (H2L) ligand reacted with equimolar amounts of FeBr2 and 2 equiv of triethylamine in air affords [FeIII(L-L)Br]0 (1), where (L-L)2- is a pentacoordinate ligand formed from the oxidative dimerization of L2- via disulfide bridge formation. Reaction of H2L with RuCl3 ¡¤ H2O and NEt3 gives a dark green-brown dinuclear complex, [Ru III2(L)2Cl2(NCCH3) 2]0 (2). Both complexes have been characterized by X-ray crystallography. A Ru-Ru single bond is evident in 2. Complex 1 has also been characterized by electron paramagnetic resonance and Moessbauer spectroscopies and magnetic susceptibility measurements that identify a high-spin Fe(III) (S = 5/2) center. Diamagnetic 2 is successively twice reversibly one-electron oxidized to produce [Ru III2(L¡¤)(L)Cl2(NCCH 3)2]+, [2]+ (S = 1/ 2), and [RuIII2(L¡¤) 2Cl2(NCCH3)2]2+, [2] 2+ (S = 0). Spectroelec-trochemical and electron paramagnetic resonance measurements identify these as ligand-based oxidations affording o-coordinated phenoxyl radicals. DFT calculations on the electron transfer series corroborate this result and that the Ru-Ru single bond is retained throughout this series.

2,9-Di-(2?-pyridyl)-1,10-phenanthroline: A tetradentate ligand for Ru(II)

The tetradentate ligand 2,9-di-(2?-pyridyl)-1,10-phenanthroline is synthesized in 62% yield by the Stille coupling of 2,9-dichloro-1,10-phenanthroline and 2-(tri-n-butylstannyl)pyridine. Treatment of this ligand with RuCl3¡¤3H2O and a 4-substituted pyridine results in the formation of a complex in which the tetradentate ligand occupies the equatorial plane and two pyridines are bound axially. The interior N-Ru-N angles vary from 76.1 to 125.6, showing considerable distortion from the 90 ideal. The lowest energy electronic transition is sensitive to the electronegativity of the 4-substituent on the axial pyridines, varying from 516 nm for the CF3 group to 580 nm for the NMe2. The oxidation potentials mirror this trend, spanning a range of 1.36-1.03 V, while the reduction potentials show less variation (-0.97 to -1.08 V). The complexes are nonemissive, presumably due to competitive nonradiative processes caused by distortion of the system. Copyright

Effect of the anchoring group in ru-bipyridyl sensitizers on the photoelectrochemical behavior of dye-sensitized TiO2 electrodes: Carboxylate versus phosphonate linkages

The effects of the number of anchoring groups (carboxylate vs phosphonate) in Ru-bipyridyl complexes on their binding to TiO2 surface and the photoelectrochemical performance of the sensitized TiO2 electrodes were systematically investigated. Six derivatives of Ru-bipyridyl complexes having di-, tetra-, or hexacar-boxylate (C2, C4, and C6) and di-, tetra-, or hexaphosphonate (P2, P4, and P6) as the anchoring group were synthesized. The properties and efficiencies of C- and P-complexes as a sensitizer depended on the number of anchoring groups in very different ways. Although C4 exhibited the lowest visible light absorption, C4-TiO2 electrode showed the best cell performance and stability among C-TiO2 electrodes. However, P6, which has the highest visible light absorption, was more efficient than P2 and P4 as a sensitizer of TiO2. The surface binding (strength and stability) of C-complexes on TiO2 is highly influenced by the number of carboxylate groups and is the most decisive factor in controlling the sensitization efficiency. A phosphonate anchor, however, can provide a stronger chemical linkage to TiO2 surface, and the overall sensitization performance was less influenced by the adsorption capability of P-complexes. The apparent effect of the anchoring group number on the P-complex sensitization seems to be mainly related with the visible light absorption efficiency of each P-complex.

INTERMETALLIC CHARGE-TRANSFER SPECTRA OF COPPER(I)-METAL(III) CENTERS IN DOPED CRYSTALS OF CsMgCl3.

When crystals of CsMgCl//3 are co-doped with small concentrations of Cu(I) and Cr(III), Mo(III), Ru(III), or Rh(III), charge-compensation stabilized Cu(I)-M(III) dimers are formed in the linear chain lattice. The absorption spectra of the crystals containing the Cu(I)-M(III) impurity centers exhibit intense, strongly polarized bands that cannot be attributed to electronic excitations localized on either Cu(I) or M(III). These bands are assigned to intermetallic charge-transfer (IT) transitions where an electron from Cu(I) is transferred to M(III). In some cases more than one IT transition is observed. The spectral properties of the Cu(I)-M(III) centers are compared to those of the analogous Li(I)-M(III) centers. A relatively simple theoretical treatment is presented that accounts for many of the features in the IT spectra of the Cu(I)-M(III) centers.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Application of 10049-08-8
