A new series of novel complexes of type cis-[Ru(CO)(2)Cl-2(L)(2)], L = 2-phenyl-1,8-naphthyridine, 2-(4′-nitrophenyl)-1,8-naphthyridine, 2-(4′-bromophenyl)-1,8-naphthyridine, 2-(4′-methylphenyl)-1,8-naphthyridine, 2-(3′-methoxyphenyl)-1,8-naphthyridine, 2-(2′-methoxyphenyl)-1,8-naphthyridine and 2-(4′-methoxyphenyl)-1,8-naphthyridine have been successfully synthesized and characterized. We found that the complexes can be directly synthesized from [RuCl2(CO)(2)](2) with high yield. The crystallographic structures of complex cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] and cis-[RuCl2(CO)(2)(2-(2′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] have been established by X-ray single crystal diffraction studies, which indicate an octahedral geometry with two 1,8-naphthyridine ligands coordinated to the metal in a N-monodentate fashion. The ruthenium(II) complexes have been studied as catalysts in the transfer hydrogenation of acetophenone. We found that complexes show moderate activities and a 100% selectivity. The best turnover frequency (390 h(-1)) is found for cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] when the substrate/catalysis ratio was 1000/1. The catalytic conditions were optimized using different substrate/catalyst and base/catalyst ratios.

i Summary of main observation and conclusion A highly efficient, simple, and clean single-step sonosynthetic procedure has been sophisticated for assembling new series of mono- and bis-pyridine dicarbonitriles from ketones, HCl, and tetracyanoethylene. The presented protocol is applicable for the preparation of a broad range of uniquely substituted pyridine dicarbonitriles and seems to be superior in comparison with other previously reported methods. The antiproliferative impact of the newly synthesized derivatives was screened towards three representative cancer cell lines (MCF-7, A549, and HCT116). Most of the evaluated derivatives showed a moderate to excellent anti-proliferative activity towards the selected cell lines. Of these, compounds 4h, 4k, 10, 12a, and 12b showed both potent anticancer activity (IC50<10 mu M) and lower cytotoxic effect (IC50 > 58 mu M) on non-tumorigenic cells (MCF-10A and NCM460), suggesting their promising potential to be lead molecules for future antitumor drug discovery. The structure-activity relationships have been also discussed. Moreover, quantum chemical studies based on Density Functional Theory (DFT) of the synthesized compounds were investigated and found to be consistent with the in vitro inhibitory activities.

A non-noble heterogeneous catalyst, ultra dispersed Co anchored on ordered porous nitrogen-riched carbon (CoN@PCN) was fabricated through a sacrificial-template pyrolysis strategy, in which SBA-15 and 1, 10-phenanthroline were employed as the hard template and ligand, respectively. Co was ultra dispersed owing to the confinement effect of SBA-15 and the strong coordination effect of Co with phenanthroline. The CoN@PCN displayed excellent catalytic activity and selectivity for the hydrogenation of nitroarenes with ammonia-borane as hydrogen donor under mild conditions, which can be ascribed to the ultra dispersed Co sites, high adsorption ability of the catalyst for ammonia-borane, large specific surface area and abundant porous structure of CoN@PCN. Based on the results of density functional theory calculations, the catalytic mechanism of CoN@PCN for the hydrogenation reaction was proposed. The recycled CoN@PCN had no obvious change in catalytic performance after five consecutive cycles, indicating its durability and recyclability.

A general strategy to synthesize mesoporous and macroporous carbon and N-doped mesoporous carbon is presented. The immobilization of cobalt catalysts with dispersed subnanometer particles in mesoporous N-doped carbon matrixes is also shown. These materials were used as catalysts for the hydrogenation of nitroarenes under considerably mild conditions. The surface area and the presence of nitrogen on the supports were demonstrated to be fundamental to disperse and stabilize the active metal species, which were responsible for the outstanding performance of these materials compared to cobalt catalysts deposited on silica, alumina, or mesoporous carbon. Finally, the ability to catalyze the hydrogenation of nitroarenes containing electron-donating groups (EDGs) and electron-withdrawing groups (EWGs) with good selectivity was also explored.

Small rhodium nanoparticles (ca. 3.5 nm) were prepared by the decomposition of an organometallic precursor under hydrogen pressure in glycerol using 1-thioglycerol as stabilizer. Full characterization in the solid state [HR-TEM, EDX, XPS] showed a fcc structure for the Rh-0/Rh(I)nanoparticles capped with thiolate ligand. Reduction of different functionalities, including nitro groups and imines, was applied to tandem reductive amination of aldehydes with primary and secondary amines, and to the synthesis ofN-substituted anilines from nitrobenzene. In addition, thiolate-capped RhNPs could be recovered and reused up to 5 runs without loss of activity nor selectivity.

A green chemical preparation of Pd nanoparticles (NPs) embedded in phytochemical resins using a plant extract from Pulicaria odora L. and PdCl2 under ambiant conditions is reported. Two batches of Pd NPs have been prepared: they present homogeneous sizes of respectively 2.2 nm and 3.2 nm depending on the preparation conditions. The Pd NPs were characterized by different techniques (TEM, HRTEM, XRD, XPS and BET) and have been successfully used for the reduction of nitroarenes in EtOH under H-2 at atmospheric pressure at rt in the presence of only 5 mequiv. of Pd. Finally the Pd NPs embedded in resin particles were easily recovered by filtration and used at least seven times without significant loss in efficiency. The residual amount of palladium found in the reaction product is very low (<0.6% of the initial amount). Therefore both preparation of the Pd NPs and their use for hydrogenations of nitroarenes are environmentally benign. Recommanded Product: 1-(4-Nitrophenyl)ethanone.

In this contribution, a protocol was established for the selective catalytic hydrogenation of nitroarenes to the correspondingN-arylhydroxylamines. The reduction of 1-(4-chlorophenyl)-3-((2-nitrobenzyl)oxy)-1H-pyrazole, an intermediate in the synthesis of the antifungal reagent pyraclostrobin that includes carbon-chlorine bonds, benzyl groups, carbon-carbon double bonds and other structures that are easily reduced, was chosen as the model reaction for catalyst evaluation and condition optimization. Extensive passivant evaluation showed that RANEY (R)-nickel treated with ammonia/DMSO (1 : 10, v/v) afforded the optimal result, especially with a particle size of 400-500 mesh. To combine the modified catalyst with continuous-flow reaction technology, the reaction was conducted at room temperature, rendering the desired product with a conversion rate of 99.4% and a selectivity of 99.8%. The regeneration of catalytic activity was also studied, and an in-column strategy was developed by pumping the passivate liquid overnight. Finally, the generality of the method was explored, and 7 substrates were developed, most of which showed a good conversion rate and selectivity, indicating that the method has a certain degree of generality.

A supported ruthenium (Ru) nanoparticle on amino-functionalized Fe3O4 (Fe3O4/NH2/Ru) was successfully prepared by a novel and simple one-pot template-free method combined with a metal adsorption-reduction procedure. The characterization results show that the introduced amino group (1,6-hexanediamine) can effectively stabilize the Ru nanoparticles and allow the particles to maintain a narrow size distribution, monodispersity and a regular morphology. Fe3O4/NH2/Ru exhibits excellent catalytic activity for the transfer hydrogenation of nitro compounds by the use of NaBH4 as the hydrogen donor. The higher activity of this catalyst was attributed to the higher dispersion and smaller particle size of Ru nanoparticles, as observed from the characterization results. Moreover, the catalyst can be easily recovered by an external magnetic field, recycled five times and reused without any loss of activity.

A UV-Vis spectrophotometric method was used to confirm the intermolecular charge-transfer complexes of the drug triamterene (TM) donor with four nitro pi-acceptors (2,4,6-trinitrophenol (PA), 4-nitrophenol (4-NP), 4-nitroacetophenone (4-NAP) and m-dinirobenzene (m-DNB)) in methanol, ethanol, acetone, acetonitrile, chloroform, dichloromethane, and dichloroethane at 25 degrees C. The spectra showed chemical shifts upon the addition of TM to solutions of the nitro acceptors in the solvents. The appearance of new bands or hyper- and hypo-chromic effects confirmed the presence of charge-transfer complexes. The spectra of the complexes of TM and nitro pi-acceptors show different absorption bands at different wavelengths for different solvents. The molar ratio method showed a result of 1:1 for the TM-PA system and 1:2 for the TM-4-NP, TM-4NAP, and TM-m-DNB charge-transfer complexes. The physical spectroscopic parameters were calculated, including the formation constant (K-CT), molar extinction coefficient (epsilon(CT)), oscillator strengths (f), ionization potential (I-p), resonance energy (R-N), and Gibbs energy (Delta G degrees). The optical band gap of the TM-nitro charge-transfer complexes was estimated, and there was clearly a relationship between the different kinds of acceptors and their optical band gaps.
