KINETICS AND MECHANISM OF THE RUTHENIUM (III) CATALYSED OXIDATION OF SOME ALIPHATIC AND CYCLIC KETONES BY PERIODATE ION IN AQUEOUS ALKALINE MEDIUM: A NOVEL BEHAVIOUR OF RUTHENIUM (III)

Kinetics of ruthenium(III) chloride catalysed oxidation of acetone, ethylmethyl ketone, isobutylmethyl ketone, pentan-2-one, cyclopentanone and cyclohexanone by sodium metaperiodate in aqueous alkaline medium at constant ionic strength is reported.The order with respect to (IO4)(1-) is found to be zero.The order with respect to (substrate) is unity for acetone, ethylmethyl ketone, isobutylmethyl ketone and cyclopentanone, whereas, pentan-2-one and cyclohexanone exhibit fractional dependence on substrate, in the entire range of substrate concentration studied.Strikingly, the order with respect to is fractional in case of the ketones where substrate dependence is unity and unity where the substrate dependence is fractional.The reaction rate increases linearly following a nearly unit dependence on (OH)(1-) at lower concentration of alkali and levels off after a particular (OH)(1-).The activation parameters have been evaluated.A suitable mechanism has been postulated and rate laws have been deduced.

Ruthenium-catalysed oxidation of alkanes with peracetic acid in trifluoroacetic acid: Ruthenium as an efficient catalyst for the oxidation of unactivated C-H bonds

The role of ruthenium catalysts for the oxidation of alkanes with peracetic acid in trifluoroacetic acid has been confirmed.

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.name: Ruthenium(III) chloride, you can also check out more blogs about10049-08-8

Mixed-Valence Ruthenium Diphosphates with a Tunnel Structure: ARu2(P2O7)2 (A=Li, Na, Ag, and Cu) and Ru2(P2O7)2

Mixed-valence ruthenium diphosphates with a tunnel structure, ARu2(P2O7)2 (A=Li, Na, Ag, and Cu), were prepared by the reaction of an amorphous ruthenium phosphate, H2RuP3O10, with Li2CO3, NaNO3, AgNO3, and Cu3(PO4)2¡¤3H2O, respectively. The structure has a three-dimensional network constructed with RuO6 and P2O7 groups, and has large tunnels where A cations reside. In the sodium system, two isotypic compounds were obtained. One was obtained as single crystals and the X-ray structure analysis showed ruthenium and sodium vacancies. Another was obtained as powder and Rietveld analysis did not indicate ruthenium vacancies. It is paramagnetic and shows an antiferromagnetic transition at around 5.5 K. The phosphate with no cation in the tunnel, Ru2(P2O7)2, was obtained as a powder upon heating amorphous ruthenium phosphate (atomic ratio P/Ru is ? 4).

Chemical and light-driven oxidation of water catalyzed by an efficient dinuclear ruthenium complex

Here splits the sun: A dinuclear ruthenium complex has been synthesized and employed to catalyze the homogeneous water oxidation (see picture; purple Ru, green Cl, blue N, red O). An exceptionally high turnover number was observed both for chemical (CeIV as the oxidant) and light-driven ([Ru(bpy)3]2+-type photosensitizers) water splitting.

Kinetics and Mechanism of Ruthenium(III) Catalysed Oxidation of Benzylamine by Hexacyanoferrate(III) in Alkaline Medium

The kinetics of ruthenium(III) catalysed oxidation of benzylamine by potassium hexacyanoferrate(III) in alkaline medium has been carried out.The reaction has been observed to be zero order with respect to oxidant and first order to lower concentrations of substrate and alkali tending towards zero order at their higher concentrations.Further, with respect to ruthenium(III), the order has been observed to be unity.A probable mechanism explaining all the observed results has been postulated.The activation parameters have been calculated.

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., Related Products of 10049-08-8

KINETICS AND MECHANISM OF RUTHENIUM(III)-CATALYSED OXIDATION OF ALLYL ALCOHOL BY MOLECULAR OXYGEN.

Oxidation of allyl alcohol by molecular oxygen catalysed by ruthenium(III) chloride in the pH range 1. 0 – 3. 0 is reported. The kinetics of the reaction, in the pH range 1. 0 – 2. 0, indicate a first-order dependence on ruthenium(III) ion and allyl alcohol concentrations and a zero-order dependence with respect to molecular oxygen concentration. The rate of oxidation was also found to be directly proportional to the hydrogen ion concentration. In the pH range 2. 0 – 3. 0, the rate of oxidation of allyl alcohol was found to be first order with respect to ruthenium(III) ion, first order with respect to allyl alcohol, and inversely proportional to hydrogen ion concentration.

Electronic and geometrical manipulation of the excited state of bis-terdentate homo- and heteroleptic ruthenium complexes

This work describes the synthesis and characterization of two new bis-terdentate Ru(ii) complexes. Compound 1 is a homoleptic complex containing two CNC N-heterocyclic carbene (NHC) based ligands, whereas compound 2 bears one CNC ligand and an ancillary terpyridine ligand. The redox and photophysical properties of both compounds have been investigated and their X-ray crystal structures determined. Complex 1 displays a close-to-perfect octahedral coordination geometry and is not luminescent at room temperature while complex 2 features room temperature and 77 K luminescence despite its partially distorted geometry. The presence of the NHC moieties brings a significant amount of electronic density to the metal centre therefore lowering its oxidation potential with respect to that of analogous polypyridyl complexes.

Water-soluble hydroxyalkylated phosphines: Examples of their differing behaviour toward ruthenium and rhodium

The reaction of P(CH2OH)3 (I) and P(C 6H5)(CH2OH)2 (II) with RuCl 3 in methanol eliminates two equivalents of formaldehyde to yield the mixed tertiary and secondary phosphine complexes all-trans-[RuCl 2(P(CH2OH)3)2 (P(CH 2OH)2H)2] (1) and [RuCl2(P(C 6H5)(CH2OH)2)2(P(C 6H5)(CH2OH)H)2] (2), respectively. There is a high degree of hydrogen-bonding interactions between the hydroxymethyl groups in 1 and 2, although the phenyl groups of the latter reduce the extent of the network compared to 1. The generation of these mixed secondary and tertiary phosphine complexes is unprecedented. Under the same reaction conditions, the tris(hydroxypropyl)phosphine III formed no ruthenium complex. The reaction of P(CH2OH)3, P(C6H 5)(CH2OH)2 and P{(CH2) 3OH}3 with [RhCl(1,5-cod)]2 in an aqueous/dichloromethane biphasic medium yielded [RhH2(P(CH 2OH)3)4]+ (3), [RhH 2(P(C6H5)(CH2OH)2) 4]+, (4) and [Rh(P(C6H5)(CH 2OH)2)4]+ (5) and [Rh(P{(CH 2)3OH}3)4]+ (6), respectively. Treating 5 with dihydrogen rapidly gave 4. The hydroxypropyl compound 6 formed the corresponding dihydride much more slowly in aqueous solution, although [RhH2(P{(CH2)3OH} 3)4]+ (7) was readily formed by reaction with dihydrogen. Two separate reaction pathways are therefore involved; for P(CH 2OH)3 and to a lesser extent P(C6H 5)(CH2OH)2, the hydride source in the product is likely to be the aqueous solvent or the hydroxyl protons, whilst for P{(CH2)3OH}3 an oxidative addition of H 2 is favoured. The protic nature of 3 and 4 was illustrated by the H-D exchange observed in d2-water. Dihydrides 3 and 4 reacted with carbon monoxide to yield the dicarbonyl cations [Rh(CO)2(P(CH) 2OH)3)3]+ (8) and [Rh(CO) 2(P(C6H5)(CH2OH)2) 3]+ (9). The analogous experiment with [RhH 2(P{(CH2)3OH}3)4] + resulted in phosphine exchange, although our experimental evidence points to the possibility of more than one fluxional process in solution.

Clusters metalliques moleculaires synthetises par voie radiolytique

The radiolytic reduction of metal ions in alcohols has been achieved under CO atmosphere.Under such conditions, metal reduction, ligation and aggregation processes compete, leading to metal complexes and molecular clusters.These products are interesting for catalytic purposes.We report here the radiolytic synthesis of compounds of Fe, Ru, Os, Co, Ir, Rh, Pt, Cu, Ag, and of some intermetallic compounds.These syntheses are carried out under very mild temperature and pressure conditions (i.e., room temperature and at most 1 atmosphere of CO).Factors favoring a high nuclearity are the concentration, the high atomic number, a weak ligand/metal ratio.It is shown that chloride ions are inhibitors of complete reduction.
