Preparation and Intramolecular C-C Coupling Reaction for Bis-benzimidazolium Salt

Bis-benzimidazolium salt 1 was prepared via a series of reactions using 2,2?-diphenol as starting material. Compound 2 was afforded through the intramolecular C-C coupling reaction of 1 under the catalysis of Pd(OAc)2. The structure of 2 is characterized through X-ray diffraction analyses, 1H NMR and 13C NMR. In 2, two boat-like seven-membered rings are contained, where the C-C bond distance newly formed is 1.461(5) A, and it is between regular C-C single bond (1.54 A) and C C double bond (1.34 A). This shows that new C-C bond has partial double-bond character. In the crystal packing of 2, the 2D supramolecular layers are formed via C-H¡¤¡¤¡¤F hydrogen bond.

NiMoS on alumina-USY zeolites for hydrotreating lignin dimers: Effect of support acidity and cleavage of C-C bonds

NiMoS on alumina, USY and mixed alumina-USY supports was studied in a batch reactor to assess the effect of support acidity in valorizing lignin dimers by hydrodeoxygenation (HDO). The reactivity of alpha-O-4 (benzyl phenyl ether), beta-O-4 (2-phenethyl phenyl ether) and 5-5? (2,2?-dihydroxybiphenyl) linkages was investigated in dodecane at 593 K and a H2 pressure of 5 MPa. A relatively fast rate of hydrogenolysis of the sp3 hybridized etheric bonds was observed for the catalyst supported on the mixed support. With the alpha-O-4 linkage, the USY supported catalyst selectively yielded deoxygenated aromatics including BTX products with fewer residual C-C dimers. For the beta-O-4 linkage, analogous trends have been observed but with more aromatics. Interestingly, with 5-5? linkages the catalyst on USY and mixed supports can break the C-C linkages without producing other intermediate C-C dimer byproducts. The results show high hydrocracking and isomerization activities of the catalyst supported on USY and mixed supports. This is consistent with XRD, Raman, XPS and TEM measurements, where enhanced dispersion of the active phase was observed. However, hydrogenation activity on the USY support is reduced to a significant degree which results in a large amount of benzene compared to NiMoS-Al2O3 that produces mostly cyclohexane. In addition, elemental analysis revealed that carbon deposition is higher on the USY-based catalyst compared to the alumina-based catalyst owing to its higher acidity. However, the potential for superior C-C bond cleavage on NiMoS-USY opens the possibility to valorize technical lignin in biorefinery processes.

Copper (II) complexes with tetradentate N4 and N2S2 ligands: effect of ligands on redox behavior and EPR parameters. Superoxide dismutase-like activity

Nine copper (II) complexes with tetradentate N4 and N2S2 (open chain or macrocyclic) ligands were prepared and studied in solution.For comparison, one N2O2 and one N3S ligand were included.EPR studies evidenced the stereochemistry around the copper (II) ion (square planar or tetrahedrally distorted).The redox or reduction potentials were obtained from electrochemical studies.UV-visible spectra gave additional information on the stereochemistry of the complexes and the deprotonation of amide ligands.The effect of ligands on redox behavior and stereochemistry is dicussed.Superoxide dismutase (SOD) activities were evidenced for the 11 complexes by spin-trapping method and by NBT assay.Unfortunately, the SOD activities do not survive bovine serum albumin in solution. – Keywords: Cu (II) complexes; EPR spectroscopy; electrochemistry; UV-visible spectroscopy; superoxide dismutase activity.

Sequential inter- and intramolecular Heck reactions have been used to construct a 26-membered carbocycle. This new tandem reaction uses strain effects to advantage in biasing the first step towards intermolecular coupling. In the second step, the lack of strain in the formation of a large ring promotes this course over polymerisation.
