The direct sulfonation is a cheap process but introduces the valuable sulfonic acid groups onto the backbone of aromatic polymers for proton exchange membrane fuel cell applications. However, the chain-scission during sulfonation degrades the polymer backbone by cleavage of the linkages between the arylene rings. If the sulfonation is conducted at a relatively high temperature for long time, the degradation may be significant. In this paper, the chain-scission mechanisms of the typical aromatic polymers are studied in terms of transition states and activation energies using density functional theory calculations, and the improvement of the overall performances of sulfonated proton conducting materials is discussed.

Jasmine is one of the most valuable commercial oil bearing plants from family Oleaceae used for the production of jasmine scent mostly in the form of concrete and absolute. Being an export commodity, development of reliable analytical methods for its jasmine species and derived products authentication and or adulterants detection should now follow. A comparative volatiles profiling of Jasminum grandiflorum L., J. multiflorum (Burm. f.) Andrews and J. sambac (L.) Aiton flowers in addition to J. grandiflorum products viz., concrete and absolute at different time periods was performed using solid phase microextraction (SPME) coupled to GC/MS. A total of 77 volatiles were identified belonging to esters, alcohols, sesquiterpenes, ketones, aldehydes, phenols, hydrocarbons and nitrogenous compounds. The phenylpropanoid/benzenoid and terpenoid classes were the major volatile classes in jasmine. Benzyl acetate was the chief scent volatile whereas major terpenoids included linalool, nerolidol, alpha-farnesene and cis-jasmone. Results revealed aroma variation among different flowers and products obtained from J. grandiflorum at different months. This study provides the first comprehensive and comparative aroma profile for Egyptian Jasminum species along with its products that could be used for its future quality control in industry.

In this study, a well-defined, novel NHC-Ni complex was developed and used to catalyze the N-arylation of alkyl- and arylamines with arylboronic acids in a rare version of Chan-Lam coupling. Although the same coupling using copper catalysts has been widely studied, the nickel-catalyzed version is rare and normally requires 10-20 mol% catalyst loading. This novel NHC-Ni complex in combination with 4,4′-dimethyl-2,2′-bipyridine, however, proved to be an effective catalyst that lowered the required catalyst loading to only 2.0 mol%.

Magnetic nanospheres are versatile candidates for both fundamental and practical applications. Before they are applied in more complicated fields, their surface must be modified by several functionalities. However, the surface modification can be affected by the magnetic nanoparticles (MNP) embedded in the polymer matrix. Herein, the synthesis of poly(acrylic acid) coated magnetic nanospheres via a multiple polymerization route is described. During the synthesis process, seed emulsion polymerization was applied to redistribute the MNP in the polymer matrix, and the relationship between the structure of magnetic nanospheres and the thickness of the grafted poly(acrylic acid) layer was investigated. The development of size, morphology and magnetic properties of the nanospheres were characterized by transmission electron microscopy, dynamic light scattering, thermogravimetric analysis, X-ray diffraction and vibrating sample magnetometry. This work would pave the way to design and preparation of new structure of functional magnetic nanospheres with precise surface modification.

Boehmite is a cubic orthorhombic structure of aluminum oxide hydroxide, which prepared via addition of sodium hydroxide solution to an aluminum nitrate solution at room temperature. In this work, the surface of boehmite nanoparticles (BNPs) modified by 3-choloropropyltrimtoxysilane (3-CPTMS), then reacted with N,N,N ‘,N ‘-tetraethyldiethylentriamine (TEDETA). Eventually, Cu-I immobilized on modified boehmite (Cu-I-TEDETA@BNPs). Structure of this catalyst was characterized using FT-IR, TEM, SEM, EDS, TGA, and AAS techniques. Finally, the catalytic activity of Cu-I-TEDETA@BNPs was studied for the synthesis of ethers and sulfides. All ethers and sulfides were obtained in high yields, which reveals the high activity of described catalyst. This catalyst was reused for several times without significant loss of its catalytic efficiency. Recovered catalyst was characterized by SEM and FT-IR techniques, which shown a good agreement with fresh catalyst. Also, heterogeneity and stability of Cu-I-TEDETA@BNPs confirmed by hot filtration test.

The Kamlet and Taft solvent basicity parameter, beta, and solvent polarity/polarizability parameter, pi*, were analyzed in terms of properties of the solvent molecules derived from computational chemistry. The analysis of beta, using a larger data set, confirms earlier conclusions that, for aprotic solvents, the basicity is determined by the partial charge on the most negative atom of the solvent molecule and by the energy of the highest energy molecular orbital associated with the donor site. For alcohols and nitrogen bases containing N-H moieties, the beta values deviate systematically from those for the non-hydrogen bonding solvents. Analysis of the polarity/polarizability parameter, pi*, shows that it depends directly on the dipole moment, and quadrupolar amplitude of the solvent and on the energy of the highest occupied molecular orbital, but decreases linearly with increasing solvent polarizability.

The adoption of solution-processed active layers in the production of thin-alm photovoltaics is hampered by the transition from research fabrication techniques to scalable processing. We report a detailed study of the role of processing in determining the morphology and performance of organic photovoltaic devices using a commercially available, low-solubility, high-molar mass diketopyrrolopyrrole-based polymer donor. Ambient blade coating of thick layers in an inverted architecture was performed to best model scalable processing. Device performance was strongly dependent on the introduction of either o-dichlorobenzene (DCB), 1,8-diiodooctane, or diphenyl ether cosolvent into the chloroform (CHCl3) solution, which were all shown to drastically improve the morphology. To understand the origin of these morphological changes as a result of the addition of the cosolvent, in situ studies with grazing-incidence X-ray scattering and optical reflection interferometry were performed. Use of any of the cosolvents decreases the domain size relative to the single solvent system and moved the drying mechanism away from what is likely liquid-liquid phase separation to solid-liquid phase separation driven by polymer aggregation. Comparing the CHCl3 + DCB cast films to the CHCl3-only cast films, we observed both the formation of small domains and an increase in crystallinity during the evaporation of DCB due to a high nucleation rate from supersaturation. This resulted in percolated bulk heterojunction networks that performed similarly well with a wide range of film thicknesses from 180 to 440 nm, making this system amenable to continuous roll-to-roll processing methods.

The main purpose of this study is to facilitate fragrance development on the basis of scientific knowledge. To this end, data on 314 perfumery raw materials (PRMs) showing the relationship between PRM odor intensity and gas concentration were obtained, and a calculation model for the data was then developed with the following features: (1) maximum PRM coverage, (2) calculating values implying odor intensity from only arbitrary gas concentration, and (3) estimating odor intensity from the calculated values directly and easily. To verify the prediction accuracy of this model, the predicted odor intensity was compared with the evaluated value for both single component and a mixture, and the same degree of root-mean-square error (RMSE) was confirmed. RMSE in the single component was 6.22 while that in the mixture was 6.69. Thus, the odor intensity of a PRM or mixture can be predicted from arbitrary gas concentrations.

The classical Sonogashira reaction of aryl electrophiles in the presence of Pd catalysts has been well established as a potent method for arylalkyne synthesis. However, the site-selective C(sp(2))-C(sp) cross-coupling strategy using a non-noble-metal catalyst is rare. An efficient alternative approach for the synthesis of arylalkynes via a Cu-catalyzed Sonogashira-type reaction promoted by visible light is described. This method enables site-selective alkynylation from aryl sulfonium salts derived from diverse arenes to a set of arylalkynes with high selectivity and high functional-group compatibility. Moreover, rapid alkynylation of drug molecules is demonstrated.

The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Methods for direct C-H trifluoromethoxylation of arenes and heteroarenes are rare, despite the importance of trifluoromethoxylated compounds for pharmaceuticals, agrochemicals, and material sciences. Especially selective C-H trifluoromethoxylation of pyridines remains a formidable challenge. Here we show a general late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagent with trifluoromethoxide anion. The reaction is mediated by silver salts under mild reaction conditions, exhibiting broad substrate scope and wide functional-group compatibility. In addition, ortho-position selective C-H trifluoromethoxylation of pyridines is observed. The method is not only applicable to the gram-scale synthesis of trifluoromethoxylated products but also allows efficient late-stage C-H trifluoromethoxylation of marketed small-molecule drugs, common pharmacophores and natural products. Selective C-H trifluoromethoxylation of pyridines remains a formidable synthetic challenge. Here, the authors report a silver-mediated late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagents with trifluoromethoxide anion.
