The reaction of various organozinc pivalates with anthranils provides anilines derivatives, which cyclize under acidic conditions providing condensed quinolines. Using alkenylzinc pivalates, electron-rich arylzinc pivalates or heterocyclic zinc pivalates produces directly the condensed quinolines of which several structures belong to new heterocyclic scaffolds. These N-heterocycles are of particular
各种有机锌新戊酸酯与邻氨基苯甲酸酯的反应提供苯胺衍生物,其在酸性条件下环化提供缩合喹啉。使用烯基新戊酸锌、富电子芳基新戊酸锌或杂环新戊酸锌直接产生稠合喹啉,其中几种结构属于新的杂环支架。由于具有最佳的空穴能带排列和大的带隙,这些 N-杂环特别适用于有机发光二极管,因为它们具有高光致发光量子产率和长激子寿命,以及甲基铵碘化铅钙钛矿太阳能电池中的空穴传输材料.
