标题:镍催化芳基碘化物与酸酐的脱羧烷基化
摘要:我们提出了镍催化的芳基碘化物的基于酸酐的脱羧烷基化.这种脱羧偶联的方法可与多种脂族羧酸酐一起使用,并能耐受合成上有用的芳族取代基.在吡啶n-氧化物和锌添加剂的氧化还原系统的辅助下,当前反应在温和条件下进行,无需光催化剂的帮助.值得注意的是,该方法具有混合脂肪族/芳香族酸酐对烷基迁移的高化学选择性.因此,它提供了一种强大的合成工具,可以通过使用容易获得的芳基羧酸(例如对羟基苯甲酸)将高价脂肪族羧酸转化为混合酸酐来改性高价值脂肪族羧酸-甲苯甲酸.我们提出了一个催化循环,该循环涉及基于自由基的脱羧反应以及随后的烷基转移至镍的关键步骤,该过程先于ni(III)的氧化诱导的c-c还原消除.

摘要:Disclosed is a composite material having a nanostructure containing metal oxide fine particles and an organic conductive polymerizable material. In this composite material, the metal oxide fine particles are joined with one another and the organic conductive polymerizable material is contained in the spaces between the fine particles. In this connection, the organic conductive polymerizable material is a copolymer which is composed of a polythiophene derivative, a thiophene or a derivative thereof and pyrrole, aniline, fluorene, furan or a derivative thereof. Also disclosed is a method for producing such a composite material. This composite material is useful for display elements such as electronic paper.
