  Copper-Catalyzed Diarylation of Activated Alkenes with Diaryliodonium Salts

  摘要：

  Cu(OTf)(2)-catalyzed diarylation of activated alkenes by using diaryliodonium(III) salts has been developed. With this method, arylated oxindoles can be easily accessed in good yields. Insights into the mechanism of copper-catalyzed arylations are discussed, and the findings are expected to help increase the level of understanding of catalytic arylations with diaryliodonium salts.

• Fast synthesis employing a microwave assisted neat protocol of new monomers potentially useful for the preparation of PDLC films
  作者：M. Teresa Barros、Ana Mouquinho、Krasimira Petrova、Mara Saavedra、João Sotomayor

  DOI：10.2478/s11532-011-0046-2

  日期：2011.8.1

  It has been reported that the length of the molecular chain and the rigidity of molecules influence the structure of the polymer network in PDLC films and hence the electro-optical properties of the composites. Herein, a series of new aromatic monomeric monomethacrylates, bismethacrylates and monovinylbenzene derivatives with a mesogenic core were successfully synthesized under microwave irradiation. The microwave assisted synthesis resulted in decreased reaction times, reduced solvent requirement, increased operational simplicity, and in most cases, improved yields and selectivity.

  Some acrylate monomers have been synthesized and copolymerized by means of free radical polymerization with methyl methacrylate and butyl methacrylate. These monomers are known to introduce the desired functionality and tune the properties of the resulting polymer. The synthesized monomers and the polymers have been characterized with NMR spectroscopy. The latter is utilized to study the polymer composition and verify the distribution of the monomers in the copolymer chain. The reactivity ratios have been estimated and concluded moderately random distribution of the monomers in the copolymer chain.

  一些丙烯酸酯单体已通过自由基聚合与甲基丙烯酸甲酯和甲基丙烯酸丁酯共聚合成。这些单体旨在引入所需的功能性并调节所得聚合物的性质。合成的单体和聚合物已通过核磁共振光谱进行表征。后者被用来研究聚合物组成并验证单体在共聚物链中的分布。反应性比率已被估算，并得出单体在共聚物链中分布较为随机的结论。
