The screening, synthesis and testing of Ru complexes generated from commercially available ligands or ligands that can be synthesised in one step, is described. The catalysts were tested for activity in the transfer hydrogenation of acetophenone by isopropanol, a probe reaction for hydrogen transfer processes between oxygenated species, often found in applications such as biomass upgrading and fine and specialty chemical synthesis. Ligand screening was conducted by in situ catalyst generation and examined NPN and NNN pincer type ligands bearing N?H or C[dbnd]N functional groups. The most active transfer hydrogenation catalysts were found to be those bearing N?H functionality, either as amino groups or as benzimidazole groups. Well-defined catalyst precursors were subsequently synthesised, including the novel complex [Ru(1)PPh3(Cl)2] (where (1) = bis(3-aminopropyl)phenylphosphine), the first reported Ru complex for this NPN ligand. Established (PN)2 and PP/NN ketone hydrogenation catalysts were also screened for transfer hydrogen capability, of which [Ru(PhPN)2Cl2] (where PhPN = 2-(diphenylphosphino)ethylamine) was the most active. Subsequently, [Ru(1)PPh3(Cl)2], [Ru(PhPN)2Cl2] and [Ru(4)(PPh3)2Cl][Cl] (where (4) = 2,6-bis(2-benzimidazolyl)pyridine) were investigated more closely to compare rate constants (determined by reaction profile regression analysis) as a more accurate measure of catalyst activity over commonly reported turn over frequencies (TOF). The effect of the reaction products on the catalyst activity was evaluated using feed spiking experiments. Catalyst deactivation was shown to be prevalent and subsequently incorporated into a simple kinetic model which enabled more accurate reaction profile fitting and provided rate constants for both the transfer hydrogenation step and deactivation reaction.

Three chloroplatinum(ii) complexes of 2,6-bis(benzimidazol-2?-yl) pyridine bearing hexaethylene glycol methyl ether are almost nonemissive in dilute aqueous solutions. Upon addition of excessive hexafluorophosphate salts to their dilute aqueous solutions, one of them was found to show a remarkable luminescence enhancement.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 14220-64-5, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 14220-64-5, Name is Bis(benzonitrile)palladium chloride, molecular formula is C14H10Cl2N2Pd

A series of heteroleptic tridentate ruthenium(II) complexes of composition [(H2pbbzim)Ru(tpy-X)](PF6)2 (1-7), where H 2pbbzim = 2,6-bis(benzimidazole-2-yl)pyridine and tpy-X = 4?-substituted terpyridine ligands with X = H, p-methyl phenyl (PhCH 3), p-bromomethylphenyl (PhCH2Br), p-dibromomethylphenyl (PhCHBr2), p-cyanomethylphenyl (PhCH2CN), p-triphenylphosphonium methylphenyl bromide (PhCH2PPh3Br), and 4?-phenylformyl (PhCHO) groups, has been synthesized and characterized by using standard analytical and spectroscopic techniques. These compounds were designed to increase the excited-state lifetime of ruthenium(II) bisterpyridine-type complexes. The X-ray crystal structure of a representative compound 2, which crystallized with monoclinic space group P2(1)/c, has been determined. The absorption spectra, redox behavior, and luminescence properties of the ruthenium(II) complexes have been thoroughly investigated. All of the complexes display moderately strong luminescence at roomtemperature with lifetimes in the range of 10-58 ns.Correlations have been obtained for theHammett sigmap parameterwith theirMLCT emission energies, lifetimes, redox potentials, protonNMRchemical shifts, etc. The anion binding properties of all the complexes as well as the parent ligand H2pbbzim have been studied in acetonitrile using absorption, emission, and 1H NMR spectral studies, and it has been observed that the metalloreceptors act as sensors for F-, AcO-, and to some extent H2PO 4-. At a relatively lower concentration of anions, a 1:1 H-bonded adduct is formed; however, in the presence of an excess of anions, stepwise deprotonation of the two benzimidazole N-H fragments occurs, an event which is signaled by the development of vivid colors visible with the naked eye. The receptor-anion binding constants have been evaluated. Cyclic voltammetric (CV) measurements carried out in acetonitrile-dimethylformamide (9:1) provided evidence in favor of anion (F-,AcO-) concentration dependent electrochemical responses, enabling 1-7 to act as suitable electrochemical sensors for F-and AcO- ions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 14220-64-5, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14220-64-5, in my other articles.

Treatment of GaCl3 with 2,6-bis(benzimidazol-2-yl)pyridine (G-BZIMPY, G = NBz, N(3,5-CF3)Bz, N-allyl and O) yielded the autoionization products [G-BZIMPYGaCl2][GaCl4] (1-4) in great yields. The Ga(iii) complex 1 was reduced to Ga(i) using K2[Fe(CO)4], resulting in the complex [(NBzBZIMPY)(Cl)Ga-Fe(CO)4] (7). GaCl3 and AlCl3 were complexed by the structurally similar bis(imino)pyridine (DIMPY) and the resulting complexes are compared to those of G-BZIMPY.

Pyrophosphate (PPi) is involved in lots of anabolism and bioenergetic processes in organisms and possesses important biological functions so that its detection is very significant. Here, we developed a selective fluorometric detection method for PPi with a copper(II) complex of 2,6-bis(2-benzimidazolyl)pyridine (bbimp), and then applied it to the detection of bacterial alarmone ppGpp. bbimp has the fluorescence emission at 395nm, but the bbimp-Cu2+ complex is hardly fluorescent because the intrinsic fluorescence of bbimp is effectively quenched by Cu2+. With the addition of PPi, however, the fluorescence emission of bbimp turns on with a 2nm red-shift, and has a linear relationship with PPi in the range of 3-90mumol/L. This method has good selectivity for PPi over other anions especially those phosphate-containing anions such as ATP, UTP, CTP, GTP, GDP, and PO43-.

C?H bond functionalization is a well-developed concept that has been thoroughly studied and gives entry to rather complex molecules without the need for previous derivatization of the substrates. The use of copper complexes in allylic C?H bond functionalization under oxidative conditions as an alternative to the well-established palladium-based methodologies remains largely underdeveloped. Here, we show for the first time a selective cross-dehydrogenative coupling reaction between underivatized allylic substrates and terminal alkynes to produce 1,4-enynes in high yields in a single step, using an in situ synthesized copper catalyst and an oxidant.

fac-[ReBr(CO)3(L1,2)] L1 = 1-ethyl-2-(pyridin-2-yl)benzimidazole (1) and L2 = 1-[(pyridin-2-yl) benzimidazole]-propyl-sulfonic acid (2), fac-[Re2Br2(CO)6L3] (3) L3 = 1,1?-(hexane-1,6-diyl)bis[2-(pyridin-2-yl)1H-benzimidazole] and fac-[ReBr(CO)3(L4,5-kappa2N1N2)] (L4 = 2,6-bis(benzimidazol-2?-yl)pyridine (4) and L5 = 2,6-bis(1-ethyl-benzimidazol-2?-yl)pyridine (5) were synthesized and fully characterized using different spectrocopic and analytical tools. The spectrocopic data showed coordination of L1-3 to fac-ReBr(CO)3via the benzimidazole and pyridine N-atoms. For 4 and 5, the absence of a two-fold axis of symmetry for L4,5 in the 1H NMR spectra reflect the kappa2N1,N2 mode of coordination. The electronic properties of 1-5 were investigated by time-dependent density functional theory calculations in the singlet and triplet states. The ligands and their Re(i) complexes were assessed for their potential antimicrobial activity. Compound 5 was screened against non-malignant cell line (noncancerous human embryonic kidney cell line (HEK293)) as well as evaluated for its blood compatibility.

Two mononuclear copper(II) complexes, [Cu(L)Cl2](CH 3OH) 2 and [Cu(L)(NO3)2], were prepared and characterized by spectroscopic and analytic methods, where L is 2,6-bis(1-butyl-1H-benzo[d] imidazol-2-yl)pyridine. Molecular structures of the complexes were determined by X-ray diffraction. The X-ray data revealed that the complexes are mononuclear and coordination geometry around Cu(II) is distorted square pyramidal. The complexes were screened for their in vitro antibacterial and antifungal activities. The complexes show moderate antifungal activities against Saccharomyces cerevisiae, Candida utilis, and Candida albicans. Moreover, the complexes inhibit the development of Escherichia coli and Klebsiella pneumoniae. 2014
