A variety of piano-stool complexes of cyclopentadienyl ruthenium(II) with imidazole-based PN ligands have been synthesized starting from the precursor complexes [CpRu(C10H8)]PF6, [CpRu(NCMe) 3]PF6 and [CpRu(PPh3)2Cl]. PN ligands used are imidazol-2-yl, -4-yl and -5-yl phosphines. Depending on the ligand and precursor different types of coordination modes were observed; in the case of polyimidazolyl PN ligands these were kappa1P-monodentate, kappa2P,N-, kappa2N,N- and kappa3N,N,N- chelating and mu-kappaP:kappa2N,N-brigding. The solid-state structures of [CpRu(1a)2Cl ]·H2O (5 .H2O) and [{CpRu(mu-kappa2-N,N- kappa’1-P-2b)}2](C6H5PO 3H)2(C6H5PO3H 2)2, a hydrolysis product of the as well determined [{CpRu(2b)}2](PF6)2.2CH 3CN (7b.2CH3CN) were determined (1a = imidazol-2-yldiphenyl phosphine, 2b = bis(1-methylimidazol-2-yl)phenyl phosphine, 3a = tris(imidazol-2-yl)phosphine). Furthermore, the complexes [CpRu(L)2]PF6 (L = imidazol-2-yl or imidazol-4-yl phosphine) have been screened for their catalytic activity in the hydration of 1-octyne.

The ligand [2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline] (L) have been prepared from 2,3-dichloroquinoxaline and 3-(2-pyridyl)-1H-pyrazole. The reaction of N,N?-bidentate chelating ligand (L) and the corresponding metal precursors [(arene)Ru(mu-Cl)Cl]2 {arene = p-cymene, benzene, hexamethylbenzene (HMB)}, [Cp?M(mu-Cl)Cl]2 {Cp? = pentamethylcyclopentadiene; M = Rh, Ir}, [CpRuCl(PPh3)2] {Cp = cyclopentadiene; PPh3 = triphenylphosphine} and [Re(CO)5Br] leads to the formation of mononuclear metal complexes having the general formula [(arene)Ru(L)Cl]+ where, arene = p-cymene (1), C6H6 (2), C6Me6 (3), [Cp?M(L)Cl]+ where, M = Rh (4), Ir (5), [CpRu(L)PPh3]+ (6) and [Re(L)(CO)3Br] (7). All these platinum group metal complexes were synthesized and isolated with PF6 counter anions except complex (6) whereas the complex (7) was isolated as a neutral complex. All these metal complexes were fully characterized by FT-IR, 1H NMR, UV-Vis and mass spectroscopic and analytical techniques. Moreover, the complexes (1-7) were determined by the single-crystal X-ray diffraction analysis. Single crystal X-ray data confirms that the coordination occurs to the N-atoms of the pyridyl and pyrazolyl moieties of the ligand. Agar well diffusion method reveals that complexes (1, 2, 4 and 5) are having good antibacterial activity against the three different bacteria, pathogenic test organisms Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli. The electronic transitions and absorption band of the complexes calculated by using time-dependent DFT method are in good agreement with the experimental results.

The acetylenes 4-HCCC6H4R [R=CH{OC(O)Me}2 (1), CHO(CH2)3O (2)], ruthenium complexes [Ru(4-CCC6H4R)(PPh3)2(eta-C 5H5)] [R=CH{OC(O)Me}2 (3), CHO (4)], [Ru(n-C=CHC6H4R)Cl(dppm)2]PF6 [n=4, R=CHO(CH2)3O (7); R=CHO, n=3 (11), 2 (15)], and [Ru(n-CCC6H4R)Cl(dppm)2] [n=4, R=CHO(CH2)3O (8); n=3, R=CHO (12)], and gold complexes [Au(n-CCC6H4R)(L)] [n=4, R=CHO, L=PPh3 (5), PMe3 (6); n=4, R=CHO(CH2)3O, L=PPh3 (9), PMe3 (10); n=3, R=CHO, L=PPh3 (13), PMe3 (14)] have been prepared, and 9 characterized by a single crystal X-ray diffraction study. Electrochemical data for the ruthenium complexes reveal reversible or quasi-reversible (alkynyl complexes) or irreversible (vinylidene complexes) processes assigned to the RuII/III couple; the effect on E1/2 values of the various structural modifications across 3, 4, 7, 8, 11, 12 and 15 are discussed. The molecular quadratic and cubic optical nonlinearities of 1-15 have been determined by the hyper-Rayleigh scattering technique at 1064 nm and the Z-scan technique at 800 nm, respectively; beta values increase on increasing the acceptor strength, proceeding from 3-acceptor-substituted to 4-acceptor-substituted arylalkynyl ligand, and an increasing phosphine donor strength, whereas gamma values increase on increasing the number of phosphine aryl groups (i.e. increasing delocalization) proceeding from PMe3 to PPh3-containing complex.

Bipyridyl appended ruthenium alkynyl complexes have been used to prepare a range of binuclear homometallic ruthenium and heterometallic ruthenium – rhenium complexes. The two metal centers are only weakly coupled, as evinced by IR and UV – vis – near NIR spectroelectrochemical experiments and supported by quantum chemical calculations. The alkynyl complexes of the type [Ru(C= Cbpy){Ln}] ({Ln} = {(PPh3)2Cp}, {(dppe)Cp}, {Cl(dppm)2}) undergo reversible one-electron oxidations centered largely on the alkynyl ligands, as has been observed previously for closely related complexes. The homometallic binuclear complexes, exemplified by [Ru(C2bpy-K2-N?N-RuClCp)(PPh3)2Cp] undergo two essentially reversible oxidations, the first centered on the (C2bpy-kappa2-N?N-RuClCp) moiety and the second on the Ru(C?Cbpy)(PPh3)2Cp fragment, leading to radical cations that can be described as Class II mixed-valence complexes. The heterometallic binuclear complexes [Ru(C2bpy-kappa2-N?N-ReCl(CO)3){Ln}] display similar behavior, with initial oxidation on the ruthenium fragment giving rise to a new optical absorption band with Re ? Ru(C?Cbpy) charge transfer character. The heterometallic complexes also exhibit irreversible reductions associated with the Re hetereocycle moiety. (Figure Presented)

The Ru/Sn heterobimetallic complexes CpRu(PPh3) 2(SnCl3) (1), (Ind)Ru(PPh3) 2(SnCl3) (2) and CpRu(TPPMS)2(SnCl3) (3) were studied as homogeneous catalysts for the electrooxidation of methanol to dimethoxymethane (DMM) and methyl formate (MF). Complexes 1, 2 and 3 exhibited significantly higher turnover numbers and current efficiencies than the corresponding mononuclear complexes CpRu(PPh3)2Cl (4) and CpRu(TPPMS)2Cl (5). The highest current efficiency (92.4%) and selectivity (100%) for DMM formation were obtained from the electrooxidation of methanol with complex 3.

The capability of donor-substituted alkynes to link different metal ions in a side-on carbon donor-chelate coordination mode is extended from the donor centers S and P to the second period element N. The complex [Tp?W(CO)2{eta2-C2(S)(NHBn)}] (Tp?=hydrido-tris(3,5-dimethylpyrazolyl)borate, Bn=benzyl) bearing a terminal sulfur atom and a secondary amine substituent is accessible by a metal-template synthesis. Subsequent deprotonation allowed the formation of remarkably stable heterobimetallic complexes with the [(eta5-C5H5)Ru(PPh3)] and the [Ir(ppy)2] moiety. Electrochemical and spectroscopic investigations (cyclic voltammetry, IR, UV/Vis, luminescence, EPR), as well as DFT calculations, and X-ray structure determinations of the W?Ru complex in two oxidation states reveal a strong metal?metal coupling but also a limited delocalization of excited states.

Cyclopentadienyl ruthenium(ii) thiosemicarbazone complexes with the general formula [Ru(eta5-C5H5)(Ac-tsc)PPh3]·Cl (1), [Ru(eta5-C5H5)(Ac-mtsc)PPh3]·Cl (2), [Ru(eta5-C5H5)(Ac-etsc)PPh3]·Cl (3) and [Ru(eta5-C5H5)(Ac-ptsc)PPh3] (4) were synthesized and characterized by various spectroscopic techniques (1H NMR, 13C NMR, IR and UV-vis). The molecular structures of the representative complexes 2 and 4 were studied by single-crystal X-ray diffraction. The interactions of all the ligands and complexes with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) were studied using UV-vis and fluorescence emission spectroscopy. The results of binding studies revealed that the effective binding potentials of the complexes were higher than those of their parent ligands. All the new complexes 1-4 were investigated for their in vitro cytotoxic activity against MCF-7 human breast cancer cell line. All the complexes significantly inhibited cell proliferation in MCF-7 cells in a dose-dependent manner. Cytological observations via an inverted phase contrast microscope and a Hoechst 33342/PI dual-staining assay showed typical apoptotic morphology of cancer cells upon treatment with complexes 2 and 3. It can thus be suggested that the complexes 2 and 3 are modulated by apoptosis. The findings of the present study indicated that complexes 2 and 3 may become potent drugs for the treatment of cancer-related diseases only after further investigation.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a patent, introducing its new discovery.

The synthesis of novel heterobimetallic derivatives of general formula [RuClCp(PPh3)-mu-dmoPTA-1kappaP:2kappa2N,N?- M(acac-kappa2O,O?)2] (M = Ni (3), Zn (4); dmoPTA = 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane) is described. The preparations of the ruthenium-cobalt analogue (M = Co (2)) and the starting compound [RuClCp(HdmoPTA-kappaP)(PPh3)](CF3SO 3) have been revised and their yield improved. Similar to 2, the solid state structures of 3 and 4 show that the dmoPTA-P and the dmoPTA-N CH3 atoms are involved in the coordination to the {RuCpCl(PPh 3)} and {M(acac)2} moieties, respectively. The size of the diffusing units is almost the same for the three binuclear complexes, indicating that they exhibit similar solution structures. The diamagnetic ruthenium-zinc derivative was fully characterized in solution at 193 K by NMR as two diastereomeric pairs of enantiomers (R-Ru, Delta-Zn; R-Ru, Lambda-Zn; S-Ru, Delta-Zn; S-Ru, Lambda-Zn). Finally, the electrochemical properties of the complexes have been investigated by cyclic voltammetry.

An efficient method for the synthesis of beta-hydroxy and beta-amino ketones from allylic alcohols catalyzed by Ru(eta5-C 5Ph5)(CO)2Cl is described. The influence of the stereoelectronic properties of the catalyst on the reaction outcome has been studied. Optimization of the reaction conditions supressed the formation of undesired side products such as saturated ketones, benzyl alcohols, and alpha,beta-unsaturated ketones. Several aromatic and aliphatic allylic alcohols have been reacted with a large variety of aldehydes or imines to produce beta-hydroxy ketones or beta-amino ketones, respectively, in yields up to 99a%. Based on experimental data, a mechanism via ruthenium alkoxides and ruthenium aldoxides is proposed. In addition, a C-bound ruthenium enolate has been characterized. beta-Hydroxy and beta-amino ketones are synthesized from allylic alcohols and aldehydes or imines, respectively. The coupling reaction is catalyzed by Ru(eta5-C5Ph5)(CO) 2Cl. Mechanistic investigations support a mechanism via ruthenium alkoxide intermediates.
