Ligand displacement reactions of the complex [CpRu(PPh3)2Cl] were investigated with N3 terdentate ligands, 4?-phenyl-2,2?: 6,2?-terpyridine (Phterpy) and 1,4-bis(2,2?: 6?,2?-terpyridin-4-yl)benzene (diterpy). The [CpRu(PPh3)2Cl] reacted with these ligands to form stable complexes of the type [CpRu(PPh3)(Phterpy)]X (X = Cl-, PF-6) and [{CpRu(PPh3)}(diterpy){Ru(PPh3)Cp}]X2 (X = CL- PF-6) where the respective ligands coordinate in a bidentate fashion. The X-ray crystal structure of the former complex was determined showing octahedral geometry about the metal center assuming the cyclopentadienyl ligand occupying three coordination sites and Phterpy acts as a bidentate ligand.

This paper reports on the reaction of [CpM(PPh3)2(L)]+/0(Cp = eta5-C5H5; M = Os, L = CH3CN, DMSO Br; M = Ru, X = Cl, CH3CN) with diethyldithiocarbamate (S2 CNEt2-). The exceptional kinetic stability of [Os-PPh3] compared to [Ru-PPh3] is reflected from the isolation of the monodentate diethyldithiocarbamate complex [CpOs(PPh3)2(kappa1-S2CNEt2)] (3) and the bidentate diethyldithiocarbamate complex [CpRu(PPh3)(kappa2-S2CNEt2)] (5) as the only products. The structure of [CpOs(PPh3)2(CH3CN)]BF4 (2 · BF4) and 5 were determined by X-ray diffraction.

Reactions of ethyne with [Ru3(mu-dppm)(CO)10] have given isomeric complexes [Ru3(mu3-C6H6)(CO) 6(dppm)], one of which, 2, contains the dppm chelating an Ru-atom, together with a hexatrienetriyl ligand attached to the Ru3 cluster to form a methylideneruthenacyclohexadiene system. The second isomer 3 contains the dppm bridging an Ru-Ru bond, with the C6H6 ligand forming a vinylruthenacyclopentadiene system. Also isolated was the open-chain Ru3 complex 4 containing a ruthenacyclopentadiene attached to the central Ru-atom; the other Ru-Ru vector is bridged by a PPh2CHPPh2C4H5 ligand, formed by a novel insertion of two ethyne molecules into an Ru-P bond. The reaction of ethyne with [Ru3(mu-H)(mu3-C2H 2)(CO)9] proceeded by attack at the coordinated alkyne and at the cluster to give a cluster-bonded PPh2CH2PPh2CCH system in 7. Thermolysis of [Ru3(mu-H)(mu3-C2SiMe3) (mu-dppm)(CO)7] (8; refluxing MeOH) in the presence of KF gave [Ru6(mu-CCH2)2(mu-dppm)2(CO) 12] (9; 80%); similar reactions carried out with [RuClCp(PPh3)2] also present gave 9 (67%) together with [Ru3(mu-H)(mu3-C2H)(mu-dppm)(CO) 6(PPh3)] (11; 23%). The molecular structures of 2, 3, 4, 7, 9, and 11, some as differently solvated forms, have been determined by single-crystal X-ray studies.

Several ruthenium complexes of the CpRuX(PPh3)2 type, where X=Cl, Br, I, NCS, NCO, CN, BH4, H, D, and some of the CpRuS2CZ(PPh3) type, where Z=NR2 or OR, were obtained.The hydride CpRuH(PPh3)2 was obtained in high yield by reaction of CpRuCl(PPh3)2 with ROM (R=alkyl, M=alkali metal).The other complexes were obtained by ligand exchange of the chloride or hydride with MX salts or HX acids, respectively.Reaction of chloride or hydride with cyclopentadiene led to ruthenocene.However, when pyrrole was used instead of cyclopentadiene, it was not possible to obtain azaruthenocene in this way.

Application of 32993-05-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

The catalytic activity of a series of ruthenium(II) complexes in azide-alkyne cycloadditions has been evaluated. The [Cp*RuCl] complexes, such as Cp*RuCl(PPh3)2, Cp*RuCI(COD), and Cp*RuCl(NBD), were among the most effective catalysts. In the presence of catalytic Cp*RuCI(PPh3)2 or Cp*RuCl(COD), primary and secondary azides react with a broad range of terminal alkynes containing a range of functionalities selectively producing 1,5-disubstituted 1,2,3-triazoles; tertiary azides were significantly less reactive. Both complexes also promote the cycloaddition reactions of organic azides with internal alkynes, providing access to fully-substituted 1,2,3-triazoles. The ruthenium-catalyzed azide-alkyne cycloaddition (RuAAC) appears to proceed via oxidative coupling of the azide and alkyne reactants to give a six-membered ruthenacycle intermediate, in which the first new carbon-nitrogen bond is formed between the more electronegative carbon of the alkyne and the terminal, electrophilic nitrogen of the azide. This step is followed by reductive elimination, which forms the triazole product. DFT calculations support this mechanistic proposal and indicate that the reductive elimination step is rate-determining.

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 32993-05-8 is helpful to your research., Application of 32993-05-8

The catalytic activity of a series of ruthenium complexes for C-H amination reactions of organic azides was investigated. The most active catalyst was found to be RuCl3, which promotes C-H amination reactions of ortho-aryl phenylazides, l-azido-2-arylvinylazides, and 1-azido-1,3-butadienes to give carbazoles, indoles, and pyrroles, respectively. Both computational and experimental results support that a two-step process involving formal electrocyclization is involved in the catalytic reaction.

A new crystalline polymorph of known chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium(II) complex [RuCl(PPh3)2(eta5-C5H5)] was obtained and characterized by various analytical methods including single-crystal and powder X-ray diffraction (XRPD) and differential scanning calorimetry (DSC) in combination with thermo-gravimetric analysis (TG-DSC). The obtained crystals of new polymorph are monoclinic, space group P21/n, with a = 11.125(4), b = 19.184(6), c = 15.946(5) A, alpha = 90, beta = 100.174(5), gamma = 90, and Z = 4. It has been found that real melting point of the complex (M.p. = 252-253 C) can be determined only in inert atmosphere while an apparent melting is observed in the range 142-150 C due oxygen promoted oxidative dissociation of triphenylphosphine ligand.

Four new cyclopentadienylruthenium(II)-acetophenone-4(N)-substituted thiosemi-carbazone complexes, with the general formula [Ru(?5-C5H5)(H-Aptsc)PPh3].Cl (1), [Ru(?5-C5H5)(H-Apmtsc)PPh3].Cl (2), [Ru(?5-C5H5)(H-Ap-etsc)PPh3].Cl (3) and [Ru(?5-C5H5)(H-Ap-ptsc)PPh3].Cl (4) were synthesised and characterised (1H NMR, 13C NMR, IR and electronic spectroscopy). The molecular structure of representative complexes 2 and 3 was confirmed by single crystal X-Ray diffraction technique. The binding ability of complexes (1?4) to calf-thymus DNA (CT DNA) and Bovine Serum Albumin (BSA) has been explored by absorption and emission titration methods. Based on the observations, an electrostatic and an intercalative binding mode have been proposed for the complexes with CT-DNA. The BSA protein binding studies have been monitored by quenching of tryptophan and tyrosine residues in the presence of complexes and static type of quenching mechanism has been proposed. In vitro free radical scavenging activity was performed by DPPH radical. The complexes (1?4) exhibited highest scavenging activity than conventional standard vitamin C (IC50 = 5.65 ± 0.12). Further, antibacterial activity of the complexes has been screened against four pathogenic bacteria such as Salmonella paratyphi, Staphylococcus aureus, Escherichia coli and Bacillus subtilis. From the results it is found that all the complexes exhibited significant activity against the pathogens and among them, complex 3 exhibited higher activity.
