Synthesis, characterization, and DNA binding of new water-soluble cyclopentadienyl ruthenium(II) complexes incorporating phosphines

The new water-soluble ruthenium(II) chiral complexes [RuCpX(L)(L?)] n+ (X = Cl, I. L = PPh3; L? = PTA, mPTA; L = L? = PTA, mPTA) (PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA = N-methyl-1,3,5-triaza-7-phosphaadamantane) have been synthesized and characterized by NMR and IR spectroscopy and elemental analysis. The salt mPTA(OSO2CF3) was also prepared and fully characterized by spectroscopic techniques. X-ray crystal structures of [RuClCp(PPh 3)(PTA)] (2), [RuCpl(PPh3)(PTA)] (3), and [RuCpl(mPTA)(PPh3)](OSO2CF3) (9) have been determined. The binding properties toward DNA of the new hydrosoluble complexes have been studied using the mobility shift assay. The ruthenium chloride complexes interact with DNA depending on the hydrosoluble phosphine bonded to the metal, while the corresponding compounds with iodide, [RuCpl(PTA) 2] (1), [RuCpl(PPh3)(PTA)] (3), [RuCpl(mPTA) 2](OSO2CF3)2 (6), and [RuCpl(mPTA)(PPh3)](OSO2CF3) (9), do not bind to DNA.

An end-on-coordinated As4 tetrahedron

One time only: The reaction of [Cp*Ru(dppe)Cl] with the potent As4 transfer reagent [Ag(eta2-As4) 2]+[pftb]- leads to [Cp*Ru(dppe) (eta1-As4)]+[pftb]- with an unprecedented end-on-coordinated As4 tetrahedron. Reaction with a second cationic ruthenium complex fragment does not lead to a second end-on coordination but to the cleavage of one basal As-As bond. This behavior, which differs from its phosphorus analogues, is rationalized by DFT calculations. Copyright

The synthesis and structural characterisation of Ru-Sn based derivatives bearing asymmetric X2ClSn- (X = Br and F) anions

Four remarkable ruthenium-tin based derivatives [Ru(eta 5-Cp)(PPh3)2SnF2Cl] (1), [Ru(eta5-Cp)(PPh3)2SnBr2Cl] (2), [Ru(eta5-Cp)(dppe)SnF2Cl] (3) and [Ru(eta 5-Cp)(dppe)SnBr2Cl] (4), Cp = C5H5, were obtained by reacting [Ru(eta5-Cp)(PPh3) 2Cl] or [Ru(eta5-Cp)(dppe)Cl] with SnX2 {X = F or Br}, respectively. They were studied by i.r. NMR (1H, 13C, 31P and 119Sn) and 119Sn-Mo?ssbauer spectroscopies. Additionally, (1) and (4) were structurally authenticated by X-ray crystallography and the results were as follows: (1) orthorhombic, Pbca, V = 15181.7(12) A?3 and Z = 8; (4) monoclinic, P21/n, V = 3503.74(8) A?3 and Z = 4.

Synthesis of new Fe(II) and Ru(II) eta5-monocyclopentadienyl compounds showing significant second order NLO properties

A series of new ruthenium(II) complexes of the general formula [Ru(eta5-C5H5)(PP)(L)][PF6] (PP = DPPE or 2PPh3, L = 4-butoxybenzonitrile or N-(3-cyanophenyl) formamide) and the binuclear iron(II) complex [Fe(eta5-C 5H5)(PP)(mu-L)(PP)(eta5-C5H 5)Fe][PF6]2 (L = (E)-2-(3-(4-nitrophenyl) allylidene)malononitrile, that has been also newly synthesized) have been prepared and studied to evaluate their potential in the second harmonic generation property. All the new compounds were fully characterized by NMR, IR and UV-Vis spectroscopies and their electrochemistry behaviour was studied by cyclic voltammetry. Quadratic hyperpolarizabilities (beta) of three of the complexes have been determined by hyper-Rayleigh scattering (HRS) measurements at fundamental wavelength of 1500 nm and the calculated static beta0 values are found to fall in the range 65-212 ¡Á 10 -30 esu. Compound presenting beta0 = 212 ¡Á 10 -30 esu has revealed to be 1.2 times more efficient than urea standard in the second harmonic generation (SHG) property, measured in the solid state by Kurtz powder technique, using a Nd:YAG laser (1064 nm).

Ruthenium derivatives of NiS2N2 complexes as analogues of bioorganometallic reaction centers

Recent results from structural biology demonstrate the catalytic significance of Ni(SR)2L2 centers attached to a second metal that binds CO, in particular the NiFe hydrogenases and acetyl CoA synthase. In experiments aimed at developing bimetallic derivatives exhibiting an affinity for CO, we have studied Ru(II) derivatives of nickel diaminodithiolates and the reactivity of these complexes toward CO and other small molecules. The reaction of [Cp*Ru(NCMe)3]OTf and NiS2N2 (S2N2 = N,N?-bis(2-mercaptoethyl)-N,N?-dimethyl-1,3-diaminoethane) gives [Cp*Ru(NiS2N2)]2(OTf)2 ([1]2(OTf)2), which exists as a monomer-dimer equilibrium in MeCN solution. Crystallographic analysis of [1]2(OTf)2 reveals a centrosymmetric dication with the Ru being quasi-octahedral and the NiS2N2 coordination sphere being relatively planar, the metal centers being linked via pairs of mu2-SR and mu3-SR units. Complex [1]22+ oxygenates and sulfidizes with O2 and S8, respectively, to give [Cp*Ru(NiS2N2)(eta2- E2)]+ (E = O, S), which were characterized spectroscopically and crystallographically. Solutions of [1]2 (OTf)2 also react with CO and MeNC to give the corresponding adducts [Cp*Ru(NiS2N2)L]OTf, where L = CO and MeNC. The vCO = 1901 cm-1 for the CO adduct indicates the excellent donating power of the NiS2N2 ligand. The Cp*Ru+ derivative of the bulkier version of the NiS2N2 species, Ni(bme*-daco) (bme*-daco = [1,5-bis(2-mercapto-2-methylpropyl)-1,5-diazacyclooctane]), is the monomeric analogue of 1+, [Cp*Ru(NCMe)(Ni-(bme*-daco))]+, whose structure was confirmed spectroscopically and crystallographically. In this species the thiolato ligands are doubly bridging and the Cp*Ru subunit adopts the usual piano-stool geometry with a terminal MeCN ligand. The MeCN is readily displaced by CO and O2 to give the corresponding adducts. The reaction of CpRu(PPh3)2Cl and NiS2N2 produced the PPh3 adduct [CpRu(NiS2N2)(PPh3)]Cl, wherein the PPh3 ligand is nonlabile. The corresponding reaction of NiS2N2 with sources of (arene)RuCl+ gave the expected adducts [(arene)Ru(Cl)(NiS2N2)]+, isolated as their OTf- salts.

N-(aryl)picolinamide complexes of ruthenium: Usual coordination and strategic cyclometalation

Reaction of five N-(4-R-phenyl)picolinamides (R = OCH3, CH 3, H, Cl, and NO2) with [Ru(PPh3) 2(CO)2Cl2] in refluxing 2-methoxyethanol in the presence of a base (NEt3) affords two geometrical isomers of a group of complexes (1-R and 2-R), each of which contains an amide ligand coordinated to the metal center as a monoanionic bidentate N,N donor along with two triphenylphosphanes, a carbonyl, and a hydride. Similar reaction of N-(naphthyl)picolinamide with [Ru(PPh3)2(CO) 2Cl2] affords an organometallic complex, 3, in which the amide ligand is coordinated to the metal center, by C-H activation of the naphthyl ring at the 8-position, as a dianionic tridentate N,N,C donor along with two triphenylphosphanes and one carbonyl. Structures of the 1-OCH 3, 2-CH3, and 3 complexes have been determined by X-ray crystallography. In all the complexes the two triphenylphosphanes are trans. In the 1-R complexes the hydride is trans to the pyridine nitrogen and in the 2-R complexes it is trans to the amide-nitrogen. All the complexes are diamagnetic, and show characteristic 1H NMR signals and intense MLCT transitions in the visible region. Cyclic voltammetry on all the complexes shows a Ru II-RuIII oxidation within 0.71-0.93 V versus SCE. An oxidation and a reduction of the coordinated amide ligand are also observed within 1.29-1.69 V versus SCE and -1.02 to -1.21 V versus SCE respectively. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Enaminones via ruthenium-catalyzed coupling of thioamides and alpha-diazocarbonyl compounds

Enaminones can be prepared via the Rh2(OAc)4- catalyzed coupling of alpha-diazocarbonyl compounds with thioamides. However, rhodium is the most expensive and least abundant among the dominant precious metals used for catalysis. Furthermore, a very limited substrate scope is known for the intermolecular rhodium catalyzed coupling reaction. Therefore, there is a need to find a more economical catalyst substitute with a broad substrate scope. In this paper, we describe the use of Ru(II) catalysts for the synthesis of enaminones. The reaction can be performed efficiently with the Grubbs first-generation catalyst or [(Ph)3P]3RuCl2 in a sealed tube. Both catalysts are much less expensive than Rh 2(OAc)4. Secondary and tertiary thioamides, when reacted with alpha-diazodiesters, alpha-diazoketoesters, alpha-diazodiketones, and alpha-diazomonoketones give enaminones. Primary thioamides give thiazole derivatives when reacted with alpha-diazomonoketones. However, with other diazo compounds, primary thioamides also give enaminones. All enaminones are obtained in good yields and with good diastereoselectivity. Accordingly, the method described in this paper is an efficient and economical alternative to the Rh2(OAc)4-catalyzed coupling process.

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: 32993-05-8, you can also check out more blogs about32993-05-8

Synthesis and redox properties of [{CpRu(L2)}2-(mu-fumaronitrile)] [OTf]2 and [CpRu(L2) (sigmaN-fumaronitrile)] [OTf] with L2 = N,N?-diisopropyl-1,4-diaza-1,3-butadiene (iPr-DAB) or L = PPh3

The reaction of [CpRu(iPr-DAB) (OTf)] (iPr-DAB = N,N?-diisopropyl-1,4-diaza-1,3-butadiene) with excess fumaronitrile yields [CpRu(iPr-DAB) (sigmaN-fumaronitrile)] [OTf] (1), which is in equilibrium with the binuclear complex [{CpRu(iPr-DAB)}2(mu-fumaronitrile)] [OTf]2 (2) and free fumaronitrile. Complex 2 could be prepared quantitatively by the reaction of [CpRu(iPr-DAB)] [OTf] with 0.5 equiv. of fumaronitrile. The reaction of [CpRu(PPh3)2] [OTf] with excess fumaronitrile led to the monomeric complex [CpRu(PPh3)2(sigmaN-fumaronitrile)] [OTf] (3), while reaction with 0.5 equiv. of fumaronitrile gave [{CpRu(PPh3)2}2(mu-fumaronitrile)] [OTf]2 (4) in 100% yield. Attempts to isolate the asymmetric compound [CpRu(iPr-DAB) (mu-fumaronitrile)CpRu(PPh3)2] [OTf]2 (5) failed since in all cases a mixture of 2,4 and the desired complex 5 was formed. The redox behavior of complexes 1 and 2 was investigated by cyclic voltammetry and UV-Vis/IR spectroelectrochemistry. The chemically irreversible one-electron reduction of both complexes is localized on the fumaronitrile ligand, as was also found for the PPh3-substituted complexes 3 and 4. These results are in sharp contrast with the chemically reversible, iPr-DAB-localized one-electron reduction of the mononuclear derivatives [CpRu(iPr-DAB)(X)]+ (X = CO, PPh3), Oxidation of the RuII centers in 1 and 2 resulted in secondary chemical reactions. The final oxidation product in the case of the binuclear complex 2 has been unambiguously identified as the cation [CpRu(iPr-DAB) (OTf)]+. This result demonstrates that the RuIII-(sigmaN-fumaronitrile) bond in the studied complexes is rather weak and easily dissociates. The oxidation-induced reactivity of 2 hence rules out the spectroscopic characterization of the mixed-valence RuIIRuIII intermediate 2+.

Cyanide-bridged arrays of 2, 3 and 4 metal atoms based on salene-iron complexes – Syntheses, structures and metal-metal interactions

Salene-Fe(III) complexes of the types LFeCl and [LFe(CN)2]- were treated with organometallic reagents to introduce the cyanide-linked units (CO)5Cr, (CO)5Mo, (CO)5W, Cp(CO)2Fe, Cp(dppe)Fe, and Cp(PPh3)2Ru. IR spectra and structure determinations revealed that all resulting complexes contained M-CN units with N coordination to the salene-Fe units. They were either dinuclear M-CN-Fe(salene), trinuclear M-CN-Fe(salene)-NC-M, or tetranuclear M-CN-Fe(salene)-Fe(salene)-NC-M species. Cyclic voltammetry showed that there are significant electronic interactions between the two outer organometallic units in the trinuclear complexes. UV/Vis spectra indicated a metal-metal charge transfer from the outer Cp(dppe)Fe groups to the central Fe(III). The magnetic moments at room temperature of the tri- and tetranuclear complexes are slightly lower than those calculated for isolated high-spin Fe(III) species.
