A series of complexes of the general formula [Ru Hbbip X Cl]+, [Ru Hbbip (X)2]2+ and [(Ru Hbbip X)2 pyz]3+; H2bbip = 2,6-bis-(2?-benzimidazyl) pyridine; pyz = pyrazine and X = 2.2?-bipyridine/1,10-phenanthroline have been synthesized and characterized by their elemental analysis, spectral (IR, 1H NMR, UV-visible and ESR) and redox data. Comparative luminescent behaviour of the complexes in the presence and absence of calf-thymus DNA has also been studied.

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 10049-08-8 is helpful to your research., Synthetic Route of 10049-08-8

Black crystals of the bismuth subchloride Bi7Cl10 were obtained by slow cooling of stoichiometric mixtures of Bi und BiCl 3 from 500C to ambient temperature. By means of thermal analyses the phase diagram Bi/BiCl3 was specified. Bi7Cl 10 decomposes peritectoidally into Bi6Cl7 and BiCl3 at 190 ± 5C. The phase barogram of the binary system was determined by total pressure measurements in the membrane zero-manometer. From the pressure functions of the bismuth chlorides as well as from measurements of the molar heat of Bi6Cl7 the thermodynamic standard data were derived: DeltaHB(Bi 6Cl7, 298) = -895 ± 5 kJ·mol-1; S(Bi6Cl7, 298) = 620 ± 10 J·mol -1 K-1; DeltaHB(Bi7Cl 10, 298) = -1310 ± 10 kJ·mol-1; S(Bi7Cl10, 298) = 730 ± 20 J·mol -1 K-1. Using these data, thermodynamic modelling of the solid-gas-equilibria were carried out in order to optimize the synthesis of Bi7Cl10. The phase-pure vapour deposition of Bi 7Cl10 is impossible due to the condensation of the dominating gas-species in the stability range of the compound. X-ray diffraction on single-crystals at room temperature revealed that Bi7Cl 10 crystallizes with the tetragonal space group I 41/a c d and the lattice parameters a = 28.235(3) and c = 39.950(4) A (Z = 64). In the crystal structure, polycations Bi95+ with the shape of tri-capped trigonal prisms are embedded in a chloro-bismuthate(III) framework ?3[Bi5Cl205-].

A novel ruthenium(II) complex, [Ru(bpy)2(pipipH2)](ClO4)2 · H2O (1) (pipipH2 = 2-(4-(1H-phenanthro[9,10-d]imidazol-2-yl)phenyl)-1H- imidazo[4,5-f][1,10] phenanthroline, bpy = 2,2?-bipyridine) has been found to act as a luminescent pH switch with extraordinary sensitivity through protonation and deprotonation of the bis-imidazole-containing ligand pipipH2 in aqueous solution at room temperature.

Reactions are described of the second-generation Hoveyda catalyst HII with amines, pyridine, and DBU (1,8-diazabicyclo[5.4.0]undec-7-ene), in the presence and absence of olefin substrates. These nitrogen bases have a profoundly negative impact on metathesis yields, but in most cases, they are innocuous toward the precatalyst. HII adducts were formed by primary and secondary amines (n-butylamine, sec-butylamine, benzylamine, pyrrolidine, morpholine), pyridine, and DBU at room temperature. No reaction was evident for NEt3, even at 60 C. On longer reaction at RT, unencumbered primary amines abstract the benzylidene ligand from HII. With 10 equiv of NH2nBu, this process was complete in 12 h, affording NHnBu(CH2Ar) (Ar = o-C6H4-OiPr) and [RuCl(H2IMes)(NH2nBu)4]Cl. For benzylamine, benzylidene abstraction occurred over days at RT. No such reaction was observed for sec-butylamine, secondary amines, NEt3, pyridine, or DBU. All of these bases, however, strongly inhibited metathesis of styrene by HII, with a general trend toward more deleterious effects with higher Bronsted basicity. Studies at 10 mol % of HII and 10 equiv of DBU, NEt3, and pyrrolidine (60 C, C6D6) indicated that the primary mechanism for decomposition involved base-induced deprotonation of the metallacyclobutane intermediate, rather than the Lewis base-mediated decomposition pathways previously established for the Grubbs catalysts. In the corresponding metathesis of ethylene, this decomposition process is rapid even at RT, highlighting the vulnerability of the less substituted metallacyclobutane.

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, Product Details of 15746-57-3

A functional ruthenium(II) complex that can act as a probe for response to hypochlorous acid (HOCl) in aqueous media with photoluminescence (PL) and electrochemiluminescence (ECL) dual-signals, [Ru(bpy)2(DB-phen)](PF6)2 [bpy: 2,2?-bipyridine; DB-phen: 5-(2,4-dimethoxybenzylamino)-1,10-phenanthroline)], has been designed and synthesized. The complex is highly luminescent both under the light excitation and the electrochemical induction. It can specifically react with HOCl in physiological pH aqueous media to afford its chlorinated derivative, [Ru(bpy)2(DBCA-phen)](PF6)2 [DBCA-phen: 5-(2,4-dimethoxybenzyl-chloroamino)-1,10-phenanthroline], accompanied by remarkable decreases in its PL and ECL intensities. The PL and ECL abatements of [Ru(bpy)2(DB-phen)](PF6)2 show good linear correlation to the concentration of HOCl with detection limits at low micromolar concentration level, and the PL and ECL responses of the complex to HOCl are highly specific without interferences of other reactive oxygen/nitrogen species. These features enabled [Ru(bpy)2(DB-phen)](PF6)2 to be used as a probe for the highly selective and sensitive detection of HOCl in aqueous media with PL and ECL dual-modes.

A new series of hexa-coordinated Ru(II) complexes of the type [Ru(L)(phen)2]X (1a?d) and [Ru(L)(bipy)2]X (2a?d) (where phen = 1,10-phenanthroline, bipy = 2,2?-bipyridine, X = NO3, BF4, ClO4, PF6) have been prepared by the reaction of (E)-2-(((5-((4-methoxyphenyl)ethynyl)pyridin-2-yl)imino)methyl)-4-((4-nitrophenyl)ethynyl)phenol (L) with [Ru(phen)2]Cl2·2H2O and [Ru(bipy)2]Cl2·2H2O. The complexes were characterized by physico-chemical and spectroscopic methods. All complexes are 1:1 conducting and diamagnetic in nature. In acetonitrile solution, the complexes displayed one reversible Ru(II)?Ru(III) oxidation couple and one irreversible Ru(III)?Ru(IV) oxidation and are sensitive to pi-acidic character of phen and bipy ligands. The complexes show room-temperature luminescence originated from the lowest energy metal-to-ligand charge transfer excited state and are sensitive to difference in size of the counter anions. All the complexes displayed second harmonic generation by Kurtz-powder technique indicating their potential for the application as a useful NLO material.

The synthesis and characterization of trans-aquatrichlorobis(5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidine-N 3)ruthenium(III) monohydrate (1) are described. Complex 1 has been analysed spectroscopically and the crystal structure has been obtained by X-ray diffraction analysis, with an Rw value of 0.032. Crystals of 1, trans-[RuCl3(H2O)(dmtp)2] ·H2O, are monoclinic and belong to the space group C2/m with a = 14.160(3), b = 17.115(3) and c = 8.550(2) A, beta = 98.51(2) and Z = 4. The three chloride ions coordinate on the ruthenium(III) ion in a mer configuration, while the two dmtp molecules coordinate in a trans configuration. The coordinated water molecule stabilizes the parallel ‘face-to-face’ trans orientation of the dmtp ligands by hydrogen bonds of both its protons with the two N(3) nitrogens of the pyrimidine rings. Compound 1 is interesting for its structural similarity to the first hydrolysis product of ruthenium (III) complexes that are currently under investigation for applications in antitumour chemotherapy. Substitution reactions in coordinating solvents like acetonitrile and dimethylsulfoxide were followed in time with conductometry, UV-Vis absorption and proton NMR spectroscopy, and show the formation of neutral trichloro complexes which are formed by substitution of the coordinated water molecule in 1 by a solvent molecule.
