Treatment of hexane-2,5-dione bis(thiosemicarbazones) ([CH3?C{= N?NH?C(=S)?NHR}?CH2]2, R = H, L1H2; CH3, L2H2?Me; CH2CH3, L3H2?Et; C6H5, L4H2?Ph) with nickel(II) acetate hydrate in refluxing ethanol gave a series of NiIIN2S2 metalloligands [Ni(L-R)] for the generation of hetero-bimetallic complexes. The reaction of equal mole each of [Ni(L1)], [Ni(L2?Me)], [Ni(L3?Et)], or [Ni(L4?Ph)] with [RuCl2(dmso)4] (dmso = dimethyl sulfoxide) at reflux resulted in isolation of neutral dinuclear ruthenium-nickel complexes [RuCl2{(Ni(L1)}(dmso)2] (1), [RuCl2{(Ni(L2?Me)}(dmso)2] (2), [RuCl2{(Ni(L3?Et)}(dmso)2] (3), and [RuCl2{(Ni(L4?Ph)}(dmso)2] (4). Interaction of [Ni(L-R)] with [CpRu(PPh3)2Cl] (Cp? = cyclopentadienyl) at room temperature led to formation of cationic dinuclear organoruthenium-nickel complexes [CpRu{(Ni(L1)}(PPh3)]Cl (5), [CpRu{(Ni(L2?Me)}(PPh3)]Cl (6), [CpRu{(Ni(L3?Et}(PPh3)]Cl (7), and [CpRu{(Ni(L4?Ph}(PPh3)]Cl (8). New bimetallic ruthenium-nickel complexes 1?8 have been characterized spectroscopically, of which molecular structures of three complexes [RuCl2{(Ni(L2?Me)}(dmso)2]¡¤CH2Cl2 (2¡¤CH2Cl2), [CpRu{(Ni(L2?Me)}(PPh3)]Cl?EtOH (6?EtOH), and [CpRu{(Ni(L3?Et}(PPh3)]Cl (7?H2O) have been established by single-crystal X-ray crystallography. Their catalytic activities for the acetalation of benzaldehyde in the presence of molecular H2 have been also investigated in this paper.

An efficient hydrogen bonding-guided ring-closing metathesis (RCM) reaction of sterically demanding homoallyl 2-(hydroxymethyl)acrylates catalyzed by the Hoveyda-Grubbs 2nd generation catalyst was developed and the reaction mechanism was explored. Adding a substituent to the hydroxymethyl group in this scaffold resulted in a class of challenging RCM substrates, although usable yields could be obtained. However, substrates bearing a 1-oxygenated alkyl group on the homoallylic carbon gave excellent RCM yields, providing a practical solution. Experimental and computational evidence indicated an unusual directing effect of OH?Cl hydrogen bonding between the substrate and Ru catalyst, which guides Ru to interact with the electron-deficient, more hindered acrylic C=C bond and thus triggers the RCM process.

The reaction velocity follows first-order kinetics with respect to the organic substrate at its lower concentrations and tends to become zero order at higher concentrations in the presence of ruthenium(III). The reaction follows first-order kinetics with respect to ruthenium(III) chloride. On the other hand, the rate of the reaction is directly proportional to the lower concentrations of ruthenium(VIII), but at higher catalyst concentrations the calalytic behavior is decreased. The reaction rate shows direct proportionality with respect to the organic substrate in the presence of ruthenium(VIII).

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).
