An efficient palladium-catalyzed three-component reaction that combines aryl halides, isocyanides, and diamines provides access to 2-aryl-2-imidazolines in yields up to 96%. Through variation of the diamine component, the reaction can be extended to the synthesis of 2-aryl-1H-benzimidazoles and 2-aryl-1,4,5,6-tetrahydropyrimidines.

Two analogous multipolar chromophores (1 and 2) that contained 2,3,8-trisubstituted indenoquinoxaline moieties have been synthesized and characterized for their two-photon absorption properties, both in the femtosecond and nanosecond time regimes. We demonstrated that their multi-branched framework structures, which incorporated appropriately functionalized indenoquinoxaline units, afforded large molecular nonlinear absorptivities within the studied spectroscopic range. Effective optical-power-limiting and stabilization behaviors in the nanosecond regime of dye molecule (2) were also investigated and the results indicated that such a structural motif could be a useful approach to the molecular design of highly active two-photon systems for quick-response and related broadband optical-suppressing applications, in particular for confronting laser pulses of a long duration. In pole position: Two multipolar chromophores that were derived from 2,3,8-functionalized indenoquinoxaline units manifest strong and wide dispersed two-photon absorption (2PA) in the NIR region under the irradiation of femtosecond laser pulses. Moreover, these model fluorophores could act as effective power-limiters/stabilizers against nanosecond laser pulses within the same spectroscopic regime. Copyright

Application of 52409-22-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst.

Nineteen polychlorinated biphenyl (PCB) congeners, such as 2,2?,3,3?,6-pentachlorobiphenyl (PCB 84), display axial chirality because they form stable rotational isomers, or atropisomers, that are non-superimposable mirror images of each other. Although chiral PCBs undergo atropselective biotransformation and atropselectively alter biological processes, the absolute structure of only a few PCB atropisomers has been determined experimentally. To help close this knowledge gap, pure PCB 84 atropisomers were obtained by semi-preparative liquid chromatography with two serially connected Nucleodex beta-PM columns. The absolute configuration of both atropisomers was determined by X-ray single-crystal diffraction. The PCB 84 atropisomer eluting first and second on the Nucleodex beta-PM column correspond to (aR)-(?)-PCB 84 and (aS)-(+)-PCB 84, respectively. Enantioselective gas chromatographic analysis with the beta-cyclodextrin-based CP-Chirasil-Dex CB gas chromatography column showed the same elution order as the Nucleodex beta-PM column. Based on earlier reports, the atropisomers eluting first and second on the BGB-172 gas chromatography column are (aR)-(?)-PCB 84 and (aS)-(+)-PCB 84, respectively. An inversion of the elution order is observed on the Cyclosil-B gas chromatography and Cellulose-3 liquid chromatography columns. These results advance the interpretation of environmental and human biomonitoring as well as toxicological studies.

Alternating copolymers, poly(2,5-bis(2-decyltetradecyl)-3,6-di(furan-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione-b-(E)-1,2-di(furan-2-yl)ethene) (P(FDPP-FVF)) and poly(2,5-bis(2-decyltetradecyl)-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione-b-(E)-1,2-di(furan-2-yl)ethene) (P(ThDPP-FVF)), composed of (E)-1,2-di(furan-2-yl)ethene and diketopyrrolopyrrole, were synthesized and studied for solution-processable organic field effect transistors (OFETs). Highest hole mobilities of 0.45 and 0.24 cm2 V-1 s-1 were measured for P(FDPP-FVF) and P(ThDPP-FVF), respectively, in bottom gate-bottom contact transistor devices. Atomic force microscopy and grazing incidence X-ray diffraction experiments were employed to investigate the crystallinity and morphology for the spin-cast polymer films. It is noteworthy that the thermally annealed P(FDPP-FVF) film exhibited higher crystallinity and small pi-stacking distance of 3.47 A. Moreover, considering the easy synthesis from renewable furfural and better performance of P(FDPP-FVF), our results provide an alternative design strategy for the synthesis of solution-based semiconducting polymers from renewable furan derivatives for OFETs.

A series of low band gap polymers composed of benzotriazole and benzo[1,2-b:4,5-b?]dithiophene derivatives were synthesized using a Stille cross-coupling reaction for use in organic photovoltaic devices. Linear or branched alkyl groups were incorporated into the benzothiazole-based accepting monomer part, and alkoxy or alkylthiophene groups were introduced to benzo[1,2-b:4,5-b?]dithiophene-based donating monomer part. Changes in photo-physical properties of the polymers by the structural modification of the donor-acceptor type low band gap polymers were investigated. The synthesized polymers were soluble in common organic solvents, and the resulting polymer solutions could be used to form smooth and uniform thin films by spin-casting. The synthesized polymers were found to exhibit good thermal stability, losing less than 5% of their weight upon heating to approximately 300C. The intra-molecular charge transfer interaction between the electron donating and electron accepting blocks in the polymeric backbone induced a broad absorption from 300 to 650 nm. The optical band gap energies of the polymers were measured to be 2.03-1.90 eV depending on the polymer structure. Solution-processed field-effect transistors were fabricated and characterized using the polymers as p-type channel materials. Bulk hetero-junction photovoltaic devices were fabricated using the polymers with [6,6]-phenyl C71-butyric acid methyl ester (PC71BM) as the electron acceptor. One of the fabricated device showed the maximum power conversion efficiency of 3.20% under AM 1.5 G (100 mW/cm2) conditions.

A palladium-catalyzed enantioselective sequential ring-opening/cross-coupling of cyclobutanones is disclosed that provides chiral indanones bearing C3-quaternary stereocenters. The reaction process involves palladium-catalyzed nucleophilic addition of cyclobutanones and aryl halides, enantioselective beta-carbon elimination, and intermolecular trapping of a transient sigma-alkylpalladium complex with boronic acids. Alternatively, an intramolecular cyclopropanation is realized through C?H bond functionalization in the absence of external coupling reagents, affording chiral cyclopropane-fused-indanones in good yields and enantioselectivity.
