We report here the synthesis and characterization of a series of p-type copolymers, which combine a fluorinated quinoxaline (FQ) acceptor unit either with a differently substituted benzodithiophene (BDT) or an unsubstituted thieno[3,2-b]thiophene (TT). The effect of the structural modifications on the photochemical stability of the resulting films is investigated and then correlated with the photovoltaic performance and lifetime measurements of corresponding photovolatic devices. To this end, we firstly studied the intrinsic stability of each polymer film by monitoring the UV-vis absorption decay, under simulated sunlight, as a function of ageing time. Bulk heterojunction solar cells, based on these polymers as donor materials, were fabricated and tested. Beside the initial values, we monitored the photovoltaic performance during prolonged light soaking in order to evaluate and compare the photostability of more complex systems such as working solar cells.

The unique properties conferred by the incorporation of fluorine into organic molecules has resulted in the widespread use of organofluorine compounds in the pharmaceutical and agrochemical industries. In contrast, organofluorine compounds are exceedingly rare in nature. The dearth of chiral pool organofluorine compounds necessitates the development of stereoselective methods for the incorporation of carbon?fluorine bonds into organic molecules. A wide variety of catalytic, enantioselective fluorination methods have been developed to address this challenge, including Lewis acid catalysis, organocatalysis, transition metal catalysis, and phase transfer catalysis. Using these methods, carbonyl compounds, alkenes, allylic electrophiles, aziridines, and epoxides have been engaged in catalytic, enantioselective fluorination reactions. This chapter provides a comprehensive review of the methods available for the catalytic, enantioselective construction of carbon?fluorine bonds and is subdivided into electrophilic and nucleophilic fluorination reactions. The chapter also provides a comparison with diastereoselective transformations and enantioselective functionalization reactions of fluorinated substrates.

Metal-coordinating directing groups have seen extensive use in the field of transition-metal-catalyzed alkene functionalization; however, their waste-generating installation and removal steps limit the efficiency and practicality of reactions that rely on their use. Inspired by developments in asymmetric organocatalysis, where reactions rely on reversible covalent interactions between an organic substrate and a chiral mediator, we have developed a transient-directing-group approach to reductive Heck hydroarylation of alkenyl benzaldehyde substrates that proceeds under mild conditions. Highly stereoselective migratory insertion is facilitated by in situ formation of an imine from catalytic amounts of a commercially available amino acid additive. Computational studies reveal an unusual mode of enantioinduction by the remote chiral center in the transient directing group.

The synthesis of chiral, nonracemic difluoromethylthio (SCF2H) compounds that contain a tetrasubstituted stereogenic center is reported. Racemic alpha-SCF2H-beta-ketoallylesters 5 were initially prepared by an electrophilic difluoromethylthiolation of beta-ketoallylesters 6, followed by a Pd-catalyzed Tsuji decarboxylative asymmetric allylic alkylation (DAAA) to provide a wide variety of chiral, nonracemic alpha-allyl-alpha-SCF2H-ketones (4) with high enantiopurity. This strategy can be extended to the enantioselective synthesis of chiral, nonracemic alpha-allyl-alpha-trifluoromethylthio(SCF3)-ketones (7).

A novel approach to produce diaryl sulfoxides from aryl benzyl sulfoxides is reported. Optimization of the reaction conditions was performed using high-throughput experimentation techniques. The [Pd(dba)2]/NiXantPhos catalyst system successfully promotes a triple relay process involving sulfoxide alpha-arylation, C-S bond cleavage, and C-S bond formation. The byproduct benzophenone is formed by an additional palladium-catalyzed process. It is noteworthy that palladium-catalyzed benzylative C-S bond cleavage of sulfoxides is unprecedented. A wide range of aryl benzyl sulfoxides, as well as alkyl benzyl sulfoxides with various (hetero)aryl bromides were employed in the triple relay process in good to excellent yields (85-99 %). Moreover, aryl methyl sulfoxides, dibenzyl sulfoxides, and dimethylsulfoxide could be utilized to generate diaryl sulfoxides involving multiple catalytic cycles by a single catalyst. Three for one: The [Pd(dba)2]/NiXantPhos (dba=dibenzylideneacetone) catalyst system successfully promotes a triple relay process involving sulfoxide alpha-arylation, C-S bond cleavage, and C-S bond formation to give diaryl sulfoxides (see picture).

We synthesized a recyclable palladium ionic catalyst, Ti0.97Pd0.03O1.97, using a solution combustion method (SCM), and characterized by XRD and Rietveld refinement. The synthesized Pd ionic catalyst is stable, insensitive to moisture and air, and easy to handle. The new catalyst has exhibited a phenomenal result for the Suzuki-Miyaura cross-coupling reaction with a broad substrate scope, and the reaction proceeds in an aqueous medium. The new catalyst proved beneficial and produced excellent yields irrespective of aryl halide used in the reaction (electron-rich or electron-poor or heterocyclic compounds) and shown a turnover frequency (TOF) of 14?25 h?1 for different reactions. The catalyst was coated on a cordierite monolith (Mg2Al4Si5O18), which enhanced the applicability of the catalyst, and made the handling and recycling of the catalyst very easy. Suzuki Miyaura reaction was carried out using both Pd-powder catalysts as well as the Pd-coated honeycomb, which gave almost similar results. We have demonstrated the recyclability of Pd coated cordierite monolith and shown the superiority of the catalyst over the other Pd catalysts for the Suzuki-Miyaura reaction.

Pre-steady-state kinetic analysis is a powerful and widely usedmethod to obtain multiple kinetic parameters. This protocol provides a step-by-step procedure for pre-steady-state kinetic analysis of single-nucleotide incorporation by a DNA polymerase. It describes the experimental details of DNA substrate annealing, reaction mixture preparation, handling of the RQF-3 rapid quench-flow instrument, denaturing polyacrylamide DNA gel preparation, electrophoresis, quantitation, and data analysis. The core and unique part of this protocol is the rationale for preparation of the reaction mixture (the ratio of the polymerase to the DNA substrate) and methods for conducting pre-steady-state assays on an RQF-3 rapid quench-flow instrument, as well as data interpretation after analysis. In addition, the methods for the DNA substrate annealing and DNA polyacrylamide gel preparation, electrophoresis, quantitation and analysis are suitable for use in other studies.
