The complex [(eta5-MeC5H4)Ru(DPVP)2(CH3 CN)]PF6 (4) (DPVP = Ph2PCH=CH2) loses CH3CN under vacuum to produce the phosphaallyl complex [(eta5-MeC5H4)Ru(eta1-DPVP)( eta3-DPVP)]PF6 (6) and reacts with Me3SiC?CH and PhC?CH in CH2Cl2-CH3OH solutions to form the methoxymethylcarbene [(eta5-MeC5H4)(DPVP)2Ru=C(OCH 3)(CH3)]PF6 (7) and the carbonyl complex [(eta5-MeC5H4)Ru(DPVP)2(CO)]PF 6 (8), respectively. In contrast [(eta5-MeC5H4)Ru(DPVP)(CO)(CH3CN)] PF6 (15) does not lose CH3CN to form a phosphaallyl complex. The structures of the complexes described herein have been deduced from elemental analyses, infrared spectroscopy, 1H, 13C{1H}, 1H NOE, where appropriate by 31P{1H} NMR spectroscopy and in eight cases by X-ray crystallography.

Novel multidentate pyridyl-aminophosphinite (L1) and pyridyl-phosphoramidite (L2) ligands of N^P^P^N-donor system have been synthesized via a series of simple steps. The ligands are symmetrical and as a result, their reactions with [Ru(p-cymene)Cl2]2 and [Ru(benzene)Cl2]2 lead to the formation of four monodentate bimetallic complexes (1?4) that retain the symmetry of the ligands. Meso and racemic mixtures (rac) of bidentate bimetallic complexes 5?8 were formed from the monodentate complexes through coordination of the pyridine nitrogen atoms to the two metal centers. The isomerism occurs at each metal center, which was evidenced by 31P{1H}, 1H NMR spectroscopy and single-crystal X-ray diffraction. The complexes were active towards hydrogenation of levulinic acid (LA) to gamma-valerolactone (GVL) using formic acid as the hydrogen source. The complexes are active at relatively low temperatures and are able to perform the hydrogenation in the absence of any additional solvent apart from the reagents to give high TON of 3 600. The catalysts are recyclable up to the fourth cycle, following which 20 % loss of activity is seen.

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., category: ruthenium-catalysts

In a Article，once mentioned of 37366-09-9, Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer

On the basis of isolated diastereomeric triorganylstannyl-P 5-deltacyclenes 7? and 7?, almost pure enantiomers of their destannylation products 8? and 8? are now available. These stereochemically inert cage chiral species contain a configurationally labile P1-H1 group that defines two epimers 8a and 8b of each of the enantiomers, which are connected by a rapid equilibrium. Mirror-symmetric circular dichroism (CD) spectra of the enantiomeric cages are compatible with the identification of epimers. A simulation of the CD spectrum of the major epimer 8?a relates the cage chirality of the system to the observed chiroptical effects. Both cage epimers and two of the phosphorus cage atoms are active as ligands with respect to [M(CO)5] fragments of Cr, Mo, and W. Four almost isoenergetic regio- and stereoisomers of the resulting mononuclear complexes are formed for these metals, but only one of the isomers per metal crystallized in the case of the racemic series of the complexes. The enantiopure versions of cages and cage complexes, however, did not crystallize at all, a well-known phenomenon for chiral compounds. CD spectra of the optically active complex isomer mixtures are close to identical with the CD spectra of the related free cages and point again to the chiral cages as the dominant source of the CD effects of the complexes. [(Benzene)RuCl2] complexes of the cage ligand 8 behave totally differently. Only a single species 12=[(benzene)RuCl2 8b] is formed in almost quantitative yield and the minor epimer 8b plays the role of the ligand exclusively. The reaction works as well for the separated enantiomeric cage versions to yield the highly enriched enantiomers 12? and 12? separately. An efficient kinetic resolution process was identified as the main reason for this finding. It is based on a high stereo- and regiochemical flexibility of the P-C cage ligand that is capable of adjusting to the specific requirements of a suitable transition-metal complex fragment. Such ligand flexibility is regularly observed in metalloenzymes, but is a very rare case in classical and organometallic complex chemistry. A rigid cage structure combined with a configurationally labile P-H center generates cage epimers of P5-deltacyclenes. In spite of five competing Patoms and the epimeric nature of the ligand, the [(benzene)RuCl2] unit forms a single complex only by kinetic resolution of the minor ligand epimer (see figure). P5-Deltacyclenes are thus bulky chiral ligands capable of adjusting their stereochemical properties according to the specific requirements of a transition-metal complex fragment.

The synthesis of new amide functionalised ruthenium(II) bis-bipyridyl dithiocarbamate receptor molecules is described. These hosts have been shown to sense the binding of anions electrochemically. Proton NMR titration studies in dmso-d6:MeCN-d3 (1:1) solvent mixtures indicate that the receptors selectively bind dihydrogen phosphate. A single crystal X-ray structure of one receptor reveals the crucial role of amide-anion hydrogen bonding interactions in the binding of sulphate. Cyclic and square wave voltammetric investigations demonstrate that the receptors can sense the binding of anions electrochemically. The addition of dihydrogen phosphate induced the largest cathodic perturbation of the metal centred Ru(II)/(III) dithiocarbamate redox couple (DeltaE = 180 mV).

Electric Literature of 15746-57-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

The stepwise synthesis of several novel Ru(tris(pp)) complexes (pp = 4,4′-disubstituted-2,2′-bipyridine; substituent = H, Me, chiral ester, or chiral amide) is described, where the pp ligands may be the same, or different, in each complex. All of the complexes detailed have been resolved into their pure Delta- and Lambda-enantiomers or diastereomers. The complexes, which are prepared starting from RuCl3, contain novel ligand architectures, with a range of chiral esters and amides attached to the 4,4′-positions of the bpy ligands. It was postulated that these chiral groups would be capable of inducing chirality at the metal center, but our investigations have shown this not to be the case, and in all reactions completely racemic products were formed. Resolution by chiral HPLC, and the subsequent characterization of the products through NMR, UV-vis, and circular dichroism (CD) spectroscopy, has been carried out; the characteristics of the CD spectra have been discussed with respect to the electron-donating/withdrawing ability of the groups at the 4,4′-positions. The X-ray crystal structure of the optically pure complex Lambda-[Ru(dmbpy)2(4,4′-bis((R)-(+)-alpha-phenylethylamido)-2,2′-bipyridine)] ·2PF6·2CHCl3 was obtained and solved using direct methods. This result, in conjunction with the CD spectra, enabled the complete and unambiguous assignment of the stereocenters of all of the novel Ru(tris(bpy)) complexes prepared in this investigation.

A novel anchoring ligand for dye-sensitised solar cell chromophoric complexes, 1-(2,2?-bipyrid-4-yl)-1,2,3-triazole-4,5-dicarboxylic acid (dctzbpy), is described. The new dye complexes [Ru(bpy)2(dctzbpy)][PF6]2 (AS16), [Ir(ppy)2(dctzbpy)][PF6] (AS17) and [Re(dctzbpy)(CO)3Cl] (AS18) were prepared in a two stage procedure with intermediate isolation of their diester analogues, AS16-Et2, AS17-Et2 and AS18-Et2 respectively. Electrochemical analysis of AS16-Et2, AS17-Et2 and AS18-Et2 reveal reduction potentials in the range ?1.50 to ?1.59 V (vs. Fc+/Fc) which are cathodically shifted with respect to that of the model complex [Ru(bpy)2(dcbH2)]2+ (1) (Ered = ?1.34 V, dcbH2 = 2,2?-bipyridyl-4,4?-dicarboxylic acid). This therefore demonstrates that the LUMO of the complex is correctly positioned for favourable electron transfer into the TiO2 conduction band upon photoexcitation. The higher energy LUMOs for AS16 to AS18 and a larger HOMO-LUMO gap result in blue-shifted absorption spectra and hence reduced light harvesting efficiency relative to their dcbH2 analogues. Preliminary tests on TiO2 n-type and NiO p-type DSSCs have been carried out. In the cases of the Ir(iii) and Re(i) based dyes AS17 and AS18 these show inferior performance to their dcbH2 analogues. However, the Ru(ii) dye AS16 (eta = 0.61%) exhibits significantly greater efficiency than 1 (eta = 0.1%). In a p-type cell AS16 shows the highest photovoltaic efficiency (eta = 0.028%), almost three times that of cells incorporating the benchmark dye coumarin C343.
