A synthetic procedure is described that provides access to [Ru(bpy) 3]2+ analogues in which one bpy ligand is replaced by a C,N-bidentate-coordinating carbene-benzimidazole ligand (bpy = 2,2?-bipyridine). These new complexes were prepared by first installing the chelating carbene ligand onto a Ru(cymene) platform and subsequent ligand substitution using bpy or terpy (terpy = 2:2?,6?:2??- terpyridine). The carbene ligand significantly affects the optical properties of the complex and lowers the ruthenium(II) oxidation potential substantially. Such modifications may be advantageous for the development of new classes of photosensitizer materials.

Synthesis, characterization, DNA and protein binding as well as anticancer activity of the organometallic complexes [(eta6-C6H6)RuCl(APBI)]Cl (1), [(eta6-p-MeC6H4Pri)RuCl(APBI)]Cl (2), [(eta6-C6Me6)RuCl(APBI)]Cl (3), [(eta5-C5Me5)RhCl(APBI)]Cl·H2O (4) and [(eta5-C5Me5)IrCl(APBI)]Cl·H2O (5) containing 2-aminophenyl benzimidazole (APBI) have been described. The complexes 1-5 exhibited strong DNA, protein binding and anticancer activity against cervical cancer (SiHa) cell line. Their binding with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) have been examined by absorption and emission spectral studies. Strong interactions between complexes and CT-DNA have been affirmed by absorption spectral and EthBr displacement studies, while interaction with BSA via static quenching explored by fluorescence titration, synchronous and 3D fluorescence spectroscopy. The interactions between 1-5 and DNA has also been scrutinized by 1H NMR spectral studies using guanosine as a model for DNA. These results have been supported by DFT calculations and molecular docking studies. Cytotoxicity, apoptosis and in vitro anticancer activity of 1-5 toward SiHa cell line have been investigated by MTT assay and acridine (AO)/ethidium bromide (EthBr) fluorescence staining. Overall results revealed that DNA and protein binding, as well as anticancer activity of 1-5 follows the order as 5 > 3 > 2 > 1 > 4.

Block copolymers of regioregular poly(3-hexylthiophene) (P3HT) and polyethylene (PE) were synthesized through the chain transfer of olefin-terminated P3HT in the presence of cyclooctene via ring-opening metathesis polymerization (ROMP). Subsequent hydrogenation of the poly(cyclooctene) block yielded high molecular weight, crystalline-crystalline P3HT-PE block copolymers, which are thermally stable and resistant to solvents under ambient conditions. These copolymers were characterized by 1H NMR, DSC, and WAXS and represent the first materials of a class of crystalline-crystalline semiconducting-insulating block copolymers. Copyright

The bimetallic cyano-bridged [(eta5-C5H 5)(PPh3)2Ru(mu-CN)Ru(PPh3) 2(eta5-C5H5)][PF6] (1) was prepared by reaction of [(eta5-C5H 5)(PPh3)2RuCl] with N,N?-bis(cyanomethyl) ethylenediamine. The single crystal structure determined by X-ray diffraction showed crystallization on the triclinic P1 space group with a perfect alignment of the cyanide bridges. This accentric crystallization was explored having in view the NLO properties at the macroscopic level, determined by the Kurtz Powder technique. Besides the very low efficiency values for the second harmonic generation, the value obtained for the bimetallic complex 1 showed to be higher than one of the parent complex [(eta5-C5H 5)(PPh3)2RuCN] (2).

A series of novel fused 4?-substituted 2,2?:6?, 2??-terpyridine ligands and their ruthenium(ii) complexes were prepared. The unusual 4?-substituents comprised 2,3,4,5-pentaphenylbenzene and its tert-butyl derivative (1 and 2) and the products from oxidative cyclodehydrogenation, i.e. polyaromatic fragments consisting of ten or thirteen fused benzene rings (3 and 4). The syntheses of all the ligands are discussed in terms of the demands and limitations of the Scholl reaction. The optical properties of the ligands, along with the single-crystal X-ray structures of 1 and 2, are presented. The latter show that the pentaphenylbenzene and terpyridine appendages of 1 and 2 are perpendicular in the solid state. Despite the inclusion of the large organic chromophore the absorption and emission properties of the Ru(ii) bis-terpy complexes (of ligands 1, 2 and 3) were found to be comparable to those of [Ru(terpy)2]2+. They are non-emissive at room temperature but emit at 77 K with excited state lifetimes of 11-12 mus.

The development of green, selective, and efficient catalysts, which can aerobically oxidize a variety of alcohols to their corresponding aldehydes and ketones, is of both economic and environmental significance. We report here the synthesis of a novel aerobic oxidation catalyst, a zeolite-confined nanometersized RuO2 (RuO2-FAU), by a one-step hydrothermal method. Using the spatial constraints of the rigid zeolitic framework, we sucessfully incorporated RuO2 nanoparticles (1.3 ± 0.2 nm) into the supercages of faujasite zeolite. Ru K-edge X-ray absorption fine structure results indicate that the RuO2 nanoclusters anchored in the zeolite are structurally similar to highly hydrous RuO2; that is, there is a two-dimensional structure of independent chains, in which RuO6 octahedra are connected together by two shared oxygen atoms. In our preliminary catalytic studies, we find that the RuO2 nanoclusters exhibit extraordinarily high activity and selectivity in the aerobic oxidation of alcohols under mild conditions, for example, air and ambient pressure. The physically trapped RuO2 nanoclusters cannot diffuse out of the relatively narrow channels/pores of the zeolite during the catalytic process, making the catalyst both stable and reusable.

The quinoline moieties of the metal-bound eta2-1,1?-biisoquinoline ligand of (eta6-benzene)(delta/ lambda-1,1?-biisoquinoline)halometal(II) hexafluorophosphate (metal = ruthenium, osmium; halo = chloro, iodo; 1(M = Ru, Os; X = Cl, I)) are stereotopic. The rates of atropisomerization of the delta/lambda-1,1?-biisoquinoline ligand, measured by spin-labeling NMR methods, indicate the energy barrier is higher for 1(Ru) than 1(Os); e.g., DeltaH?[1(M = Ru, X = Cl)] = 77.3(2) and DeltaH?[1(M = Os, X = Cl)] = 71.2(2) kJ mol-1. Since the crystal structures of 1(M = Ru, X = Cl) and 1(M = Os, X = Cl) reveal comparable metric parameters, steric factors associated with atropisomerization of the 1,1?-biisoquinoline ligand, essentially the deformation of the 1,1?-binaphthylene skeleton that is necessary to pass H8 and H8? past one another, are presumably equivalent for the Ru and Os derivatives. Assuming that normal bond energies are greater for the third-row transition metal than for second-row transition metals, we conclude the difference in reactivity can be attributed to electronic factors – the sigma-donor orbitals and pi-acceptor orbitals of the 1,1-biisoquinoline ligand are misdirected in the ground state but redirected in the syn transition state of atropisomerization. Thus, an inverse relationship between the kinetic and thermodynamic stabilities of 1 is observed for the misdirected ? [directed]? ? misdirected (MDM) isomerization of 1 (the more thermodynamically stable bond is more reactive). Atropisomerization of 1 represents only the second example of such an inverse free-energy relationship for a thermodynamically controlled reaction, and it contrasts with the regular relationship that has been found for the atropisomerization of related directed ? [misdirected]? ? directed (DMD) systems.

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.Product Details of 37366-09-9, you can also check out more blogs about37366-09-9

EBC-23 (2), a prostate anticancer agent, was isolated from the fruit of Cinnamomum laubatii (family Lauraceae) in the Australian tropical rainforest. Extensive NOE experiments enabled the relative stereochemistry of the proposed EBC-23 (2) structure to be determined. Total synthesis of both enantiopodes over nine linear steps, involving challenging RCM and spiroacetal cyclizations, confirmed the gross structure and relative and absolute stereochemistry.
