The catalytic activity of carbon-supported Pd nanoparticles (NPs) was investigated in the hydrogenation of anthracene at different temperatures and reaction times. These nanocatalysts were prepared by direct reduction of a palladium precursor impregnated on the carbon support. Small spherical and homogenously dispersed Pd NPs were thus achieved. Nanocatalyst performance was evaluated as a function of surface properties, including porosity, defects and Pd NPs population. High conversions and selectivities towards the hydrogenated products without cracking or ring-opening products were achieved. The selectivity of the nanocatalysts to the production of hydrogenated species depended on temperature, reaching a maximum at 300 C. At this temperature and short reaction time, the catalytic activity is thought to have been favored by the presence of a large amount of surface defects in the nanocatalysts that can promote hydrogen transfer to the anthracene molecule. On the other hand, at longer reaction times the porosity and density of Pd nanoparticles on the catalyst were the factors behind the deeper hydrogenation achieved. Finally, a plausible reaction pathway for anthracene hydrogenation in the presence of these Pd nanocatalysts was proposed.

The invention provides novel ligands for transition metal complexes which exhibit high coordination power with respect to metals by being free of substituents at the positions ortho to phosphorus or arsenic and which have electron-withdrawing power comparable to the highest level known in conventional ligands. A ligand of the invention includes a compound represented by General Formula (1): R1R2R3A or General Formula (2): R1R2A-Y-AR3R4 and having a total of 15 to 110 carbon atoms. In the formulae, A is phosphorus or arsenic; R1, R2, R3 and R4 are each independently a substituted pyridyl group having optionally different electron-withdrawing groups bonded to the positions meta to the atom A as well as hydrogen atoms bonded to the positions ortho to the atom A; and Y is a divalent group derived from a C2-20, optionally substituted and optionally heteroatom-containing, aliphatic, alicyclic or aromatic compound or from ferrocene.

A facile and efficient protocol for palladium-catalyzed regioselective C8-H acylation of 1-naphthylamine derivatives with acyl chlorides has been developed. The reaction exhibits broad functional group tolerance, and both aromatic and alpha,beta-unsaturated acyl chlorides can be effectively coupled with 1-naphthylamines. Moreover, the picolinamide moiety as a bidentate directing likely plays a key role in this regioselective transformation.

A novel approach for the synthesis of tetracyclic indoles and 7-azaindoles is reported. The strategy involves four steps, with a fast rt intramolecular alpha-arylation of ketones as key step. The reaction was inspected synthetically to achieve the synthesis of 11 novel tetracyclic structures with moderate to very good yields (39-85%). Theoretical combined with experimental studies led us to propose a probable polar mechanism (concerted SNAr).

The Pd-catalyzed acylation reactions of terminal 3-ethynyl moieties of chlorophyll-a (Chl-a) derivatives are described herein. Both acyl chlorides and acid anhydrides were valuable reagents for the coupling, resulting in the formation of pi-conjugation extended Chl-a derivatives possessing a carbonyl-ethynyl group at the C3-position. The ultraviolet-visible absorption and fluorescence emission data were obtained in solution to evaluate the optical properties of the 3-ynone-linked Chl-a derivatives.

In this work, two wide-bandgap polymers PBDTBT-1FB and PBDTBT-2FB were designed and synthesized with fluorobenzene (1FB) and difluorobenzene (2FB), respectively, which were inserted between the benzodithiophene (BDT) and benzothiadiazole units (BT) in polymer backbone. Functionalization of the phenylene unit with fluorine atom has a significantly effect on the energy levels and charge transportation properties of the polymers. Both PBDTBT-1FB and PBDTBT-2FB exhibited wide-bandgaps of ?1.98 eV with deeper-lying HOMO levels. PBDTBT-2FB containing 2FB showed better hole transportation abilities than PBDTBT-1FB due to its good film quality. As a result, polymer PBDTBT-1FB containing 1FB has reached power conversion efficiency (PCE) of 2.16%, with open circuit voltage (Voc) of 0.95 V in optimized devices. The photovoltaic performance of PBDTBT-2FB was improved by increasing its Voc up to 1.0 V, resulting in a PCE of 3.34%. The wide-bandgap polymers containing fluorinated phenylene units result in the simultaneous promotion of Voc.
