The study focuses on the Au(I)-catalyzed annulation of enynes and alkynes to synthesize multiply substituted arenes, specifically styrene and fluorene products. The researchers used a variety of enynes, propargyl esters, and gold catalysts, including cationic phosphinegold(I) complexes, AuCl, and triarylphosphitegold(I) chloride, in conjunction with silver salts like AgOTf and AgSbF6 as cocatalysts. These chemicals served the purpose of selectively accessing different arene products through precise control of the reaction conditions and catalyst counterions. The study demonstrates the power of this method to prepare complex arenes from simple starting materials and provides insights into the mechanism of the reaction.
The research focuses on the development of new aggregation-induced emission (AIE) active luminogens, specifically targeting the synthesis of efficient blue AIE emitters for undoped organic light-emitting diodes (OLEDs). The purpose of this study was to address the challenges associated with blue OLEDs, which often suffer from inferior performance due to the large band gap in blue luminogens. The researchers successfully synthesized two deep-blue fluorophores, TPE–pTPA and TPE–mTPA, along with six other compounds for comparison. These luminogens were designed to restrict the π-conjugation length, ensuring blue emission, by incorporating hole-dominated triphenylamine (TPA) and fluorene groups with high luminous efficiency, connected through unconjugated linkages. The study concluded that TPE–pTPA and TPE–mTPA exhibited the best electroluminescence performance with low turn-on voltages and high efficiencies, demonstrating that it is possible to enhance the OLED performance without sacrificing deep-blue emission through rational molecular design. Key chemicals used in the synthesis process included tetraphenylethene (TPE), triphenylamine (TPA), fluorene, and various other aromatic compounds. The researchers also utilized palladium-catalyzed Suzuki coupling reactions for the final product formation, with yields ranging from 60.4 to 85.9%. The compounds were purified and characterized using column chromatography and spectroscopic techniques.
The research focuses on the development of a more efficient and convenient method for allylic and benzylic oxidations using a reagent system comprised of tert-butyl hydroperoxide and pyridinium dichromate. The purpose of this study was to address the drawbacks of traditional chromium(VI)-based oxidation methods, such as the use of large excess reagents, large volumes of solvents, and long reaction times. The researchers found that the combination of these two reagents in a 1:1 molar ratio effectively facilitated the oxidation process under mild conditions, yielding high conversion rates and product yields. The chemicals used in the process included tert-butyl hydroperoxide, pyridinium dichromate, and various substrates such as cholesteryl acetate, dicyclopentadiene, citronellol acetate, 1-phenylcyclohexene, α-pinene, A3-carene, cycloheptene, limonene, fluorene, diphenylmethane, and tetralin, among others. The conclusions of the research highlighted the utility and simplicity of the tert-butyl hydroperoxide-pyridinium dichromate method, suggesting its potential for wide application in organic synthesis.
