Two ruthenium(II) complexes of newly designed pyrrol-azo ligands(L) and bipyridine(bpy) formulated as [Ru(L)(bpy)2]ClO4, where HL1= (4-chloro-phenyl)-(1H-pyrrol-2-yl)-diazene (1) complex 1 and HL2= (4-nitro-phenyl)-(1H-pyrrol-2-yl)-diazene for 2, were isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods. The electrochemical behavior of the complexes showed the Ru(III)/Ru(II) couple at different potentials with quasi-reversible voltammograms. The study of cytotoxicity effects of 1 and 2 on human breast cancer cells (,were isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods. The electrochemical behavior of the complexes showed the Ru(III)/Ru(II) couple at different potentials with quasi-reversible voltammograms. The study of cytotoxicity effects of 1 and 2 on human breast cancer cells (MCF 7, MDA-MB 231) and cervical cancer cell (HeLa) taking Cisplatin as a positive reference showed that 1 exhibited higher cytotoxicity against cancer cell lines than 2, but less activity than Cisplatin. The interaction of 1 with calf thymus DNA (CT-DNA) using absorption, emission spectral studies, viscosity-measurement, and electrochemical techniques has been used to determine the binding constant Kband the linear Stern-Volmer quenching constant KSV. The results indicate that 1 strongly interacts with CT-DNA in groove binding mode. The interaction of bovine serum albumin (BSA) with 1 was also investigated with the help of spectroscopic tools. Absorption spectroscopy proved the formation of a BSA-[Ru(L1)(bpy) 2]ClO4 complex.

Time-resolved infrared spectroscopy (TRIR) has been used to probe the nature of the lowest excited state of [PtII(dpphen)(CN)2] (dpphen = 4,7-diphenyl-1,10-phenanthroline) both in fluid solution at room temperature and in a glass at 77 K. The positions of the v(CN) bands in [PtII(dpphen)(CN)2] are only slightly (less than 5 cm-1) shifted upon formation of the excited state, thus supporting their assignment as the pi-pi* intraligand state. At 77 K [PtII(dpphen)(CN)2] has a highly structured luminescence with a lifetime of 170 mus, which is also characteristic of a pi-pi* excited state. In contrast, the lowest excited state of [Ru(bpy)2(CN)2] has MLCT character in both fluid solution at ambient temperature and at 77 K as shown by a large positive shift of v(CN) relative to the ground state. Also we have monitored the monomer-excimer equilibrium of [PtII(dpphen)(CN)2] in fluid solution using the ns-TRIR technique.

A systematic study on ring-closing metathesis with Grubbs II catalyst to cembranoid macrocycles is described. Acyclic terpenoids with a functional group X in the homoallylic position relative to an RCM active terminus and substituents R, R1 directly attached to the other terminal double bond were prepared from geraniol derived trienes and fragments that are based on bromoalkenes and dimethyl malonate. Such terpenoids were suitable precursors, despite the presence of competing double bonds in their framework. The size of R and R1 is crucial for successful macrocyclization. Whereas small alkyl substituents at the double bond directed the RCM towards six-membered ring formation, cross metathesis leading to dimers dominated for bulkier alkyl groups. A similar result was obtained for precursors without functional group X. In the case of unsymmetrically substituted terpenoid precursor (R=Et, R1=Me) with homoallylic OTBS or OMe group, the RCM could be controlled towards formation of macrocyclic cembranoids, which were isolated with excellent E-selectivity. The role of the substituents was further studied by quantum chemical calculations of simplified model substrates. Based on these results a mechanistic rationale is proposed.

Electric Literature of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

The photophysics of PAMAM (poly-amidoamine) based dendrimers (generations G0-G4) modified with (4, 8, 16, 32 and 64) pendant-[Ru(tpy)2]+2 (tpy is 2,2?:6?,2?-terpyridine) and [Ru(bpy)3]+2 (bpy is 2,2?-bipyridine) chromophores were studied in fluid solution at 298 K and frozen glasses at 77 K. The absorption and emission spectra, the excited-state lifetimes, and the quantum yield were obtained for both families of metallodendrimers. The behavior of these metallodendrimers parallels that exhibited by discrete molecular analogues, i.e., [Ru(tpy)2]+2 and -[Ru(bpy)3]+2, with the bipyridine derivatives exhibiting longer lifetimes and higher quantum yields when compared to the corresponding terpyridine complexes. Some generation dependent variations were also observed. The low temperature excited state lifetime for the terpyridine dendrimers, decreased linearly with the cube root of the molecular weight (and thus the dendrimer size), which should suggest an effect of the proximity of adjacent chromophores. The effects of solvent were also studied by comparing results in butyronitrile and dimethylacetamide with the latter being used as a mimic of the dendritic backbone. These results suggested that, for the higher generations, the dendritic backbone act as the solvent in affecting the photophysical behavior.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

The syntheses and characterization of three new mixed sandwich complexes involving crown thioether ligands and Group 8 metal ions are reported. These complexes are: [Ru(C5H5)(9S3)]PF6 (1), [Ru(C5H5)(10S3)]PF6 (2) and [Fe(C5H5)(IOSS)]PF6 (3), where 9S3 = 1,4,7-trithiacyclononane and 10S3 = 1,4,7-trithiacyclodecane. All three complexes have been characterized by single-crystal X-ray crystallography, and all structures show an octahedral metal center with facially coordinated carbocyclic and macrocyclic ligands. The average M-S bond lengths in 1, 2 and 3 are 2.289(2), 2.331(2) and 2.1823(7) A, respectively, and these are shorter than the M-S bond lengths in the corresponding bis 9S3 and 10S3 complexes. We propose that this distance decrease is caused by enhanced metal-thioether pi bonding due to the strong sigma-donating ability of the Cp ligand. All structures are confirmed in solution via 1H- and 13C-NMR spectroscopy. Cyclic voltammetric studies on the three heteroleptic complexes show E1/2 values that are intermediate between those of the corresponding homoleptic hexakis(thioether) complexes and metallocenes. This electrochemical behavior is also consistent with the relative sigma-donating and pi-accepting abilities of the Cp and trithioether ligands.

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.Safety of Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8

A new strategy to build caged-compounds is presented. The approach is based on heterolytic photocleavage of a metal-ligand bond in a coordination compound. A ruthenium polypyridine complex, containing the neurocompound 4-amino pyridine (4AP) is used as the core of the phototrigger. The biomolecule is released by irradiation with visible light (>480 nm). The liberated 4AP promotes the activation of a leech neuron by means of blocking its K+ channels. The syntesis, characterization, and the inherent advantages of this method are discussed. Copyright

Ru-catalyzed olefin metathesis has been successfully applied to the synthesis of biscardanol derivatives and cardanol-based porphyrins. Using Hoveyda-Grubbs catalyst (C627), the reactions were performed with various cardanol derivatives (2, 5, 7, and 9) to make novel biscardanol derivatives. With the use of the second-generation Grubbs catalyst (C848) and Ti(OiPr)4, the ring-closing metathesis of cardanol-based porphyrin 11 was carried out to afford cyclic cardanol-based porphyrin derivative 12.
