Extraction of ruthenium(III) by bisacylated triethylenetetramine from hydrochloric acid solutions is studied. Ruthenium(III) is extracted by the inner-sphere substitution (solvation-type) mechanism. The donor atoms of the secondary amine nitrogen atom of the extractant enter the inner sphere of the ruthenium(III) ion to form a donor-acceptor bond. The composition of the extracted compound is suggested on the basis of electronic, 1H NMR, and IR spectroscopy and element analysis. Copyright

One of the most efficient sensitizers presently available for photoelectrochemical solar cell applications is a ruthenium dye based on a terpyridine ligand. The voltammetric oxidation of the N,N,N-bonded thiocyanate isomer of [(H3-tctpy)RuII(NCS)3] (H3-tctpy = 2,2? :6?,2?-terpyridine-4,4?,4?-tricarboxylic acid), which is relevant to the use of the dye in photovoltaic cells, has been studied at platinum, gold, and glassy carbon electrodes. In acetonitrile, the metal-based one-electron oxidation process for the N,N,N-bonded isomer exhibits close to chemically reversible behavior under a wide range of voltammetric conditions, although the presence of surface-based reactions coupled to the charge transfer process are evident. The electrochemical quartz crystal microbalance technique revealed that dye material is adsorbed onto the electrode surface under open circuit conditions and that additional surface-based oxidation processes occur at potentials more positive than the initial metal-based oxidation process. Oxidative voltammetry in acetone is similar to that in acetonitrile. However, studies on mixtures containing S-bonded linkage isomers in this solvent show a shift in reversible potential to less positive values and a decrease in the contribution of the surface-based processes. In dimethylformamide, low temperatures (T = -55C) are necessary to observe a reversible one-electron oxidation process. Data are compared to those reported with the more commonly used [(2,2?-bipyridine-4,4?-dicarboxylic acid)2Ru(NCS)2] sensitizer.

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 20759-14-2 is helpful to your research., Synthetic Route of 20759-14-2

Surfactant-templated, mesostructured thin films are synthesized such that photoelectron donors and electron acceptors are separated spatially in the different regions of the thin film. A photoelectron donor is placed within the silica framework by using a silylated derivative of the well-known tris(bipyridine)-ruthenium(ll) cation. Selective placement of the electron acceptor is achieved by using a surfactant derivative of methyl viologen. Luminescence decay traces and luminescence spectra are collected for the electron donor in the presence of varying amounts of the electron acceptor. Because of the spatial separation of the donor and acceptor noncontact electron transfer occurs and the electron-transfer rate decreases exponentially with the distance separating the donor and acceptor. Luminescence decay traces are calculated and fit to the experimental data in order to extract a value for the contact quenching rate, ko (s-1), as well as the exponential decay constant beta (A-1) which governs how fast the electron-transfer rate decreases as a function of the donor-acceptor distance. The value beta = 2.5 ± 0.4 A-1 shows that the mesostructured material is an excellent insulator, better than frozen organic glasses or proteins and approaching that of vacuum. Combining deliberate placement methods, spectroscopy, and calculations has made possible the first measurement of beta for the silica region of mesoporous thin films.

Preparation, characterisation and crystal structures of complexes of 1,10-diphenyl-1,10-diphospha-4,7,13,16-tetrathiacyclooctadecane (18P2S4) containing nickel, iron and ruthenium are described. Reaction of 1,2-dichloroethane with PhP(CH2CH2SH)2 and caesium carbonate affords 1,10-diphenyl-1,10-diphospha-4,7,13,16- tetrathiacyclooctadecane (18P2S4) in high yield (ca. 90%). 18P2S4 slowly decomposes in solution to afford insoluble PhP(S)(CH2CH 2SCH2CH2SCH2CH2) 2P(S)Ph which was characterised by single crystal X-ray diffraction. Reaction of 18P2S4 with [Ni(H2O)6](BF4) 2 or Fe(BF4)2 affords [M(18P2S4)](BF 4)2 (M = Ni or Fe). The structure of [Ni(18P2S4)] 2+ is a tetragonally distorted octahedron in which there are two short Ni-S bonds [2.2152(6) A] and two long Ni-S bonds [2.9268(6) A]. For comparison the structure of [Ni(9PS2)2]2+ was determined and found to a have a similar, but less marked distortion, in which the difference between the long and short bonds is ca. 0.5 A. In contrast the structure of [Fe(18P2S4)]2+ is octahedral with approximately equal Fe-S bonds. The electrospray mass spectra of the cations [M(9PS2)2]2+ and [M(18P2S4)]2+ (M = Ni or Fe) all display ethene loss from the ligands as has been previously observed with trithiacyclononane complexes. The results of P-C and C-S bond rupture were also observed in the reaction of ruthenium(III) triflate with 9PS2 which unexpectedly afforded crystals containing [Ru2(S)2(18P2S4) 2], in which the two ruthenium centres are bridged by two sulfides and the two 18P2S4 ligands coordinated only through the phosphine centres. Also present in the crystals was one equivalent of tetrathiacycloundecane (12S4).

A simple route to ruthenium catalysts suitable for formamide production from amines, hydrogen and carbon dioxide is reported. The formylation of 3-methoxypropylamine has been employed as a test reaction. Highly active and selective ruthenium based catalysts were formed in situ under reaction conditions from solid RuCl3 in the presence of triphenylphosphine (PPh3) and 1,2-bis(diphenylphosphino)ethane. While RuCl3 does not catalyze the reaction effectively, the addition of phosphines led to nearly five-fold increase in rate. The achieved turnover frequencies are comparable to those of synthesized reference Ru-phosphine complexes. As a consequence of the high activity only very small amounts (?300 ppm) of both RuCl3 and the phosphine are necessary to catalyze effectively the formylation reaction. Despite the very low concentration of the Ru complex, the structure of the in situ formed active complex was elucidated by X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) spectroscopy. Both indicated similar local structure for the in situ formed complex and a Ru-reference complex after reaction.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.category: ruthenium-catalysts, 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.
