synthesizing o-bis(3-indolyl)arenes was developed by reacting indoles with 7-oxabicyclo[2.2.1]hept-5-en-2-one and derivatives thereof having no aromatic ring. All 23 unknown o-bis(3-indolyl)arenes could be obtained using this method. Palladium catalysis is useful for enlarging the π-conjugated area of o-bis(3-indolyl)arenes, delivering aryl-, alkynyl-, and alkenyl-unit-installed o-bis(3-indolyl)arenes, and
开发了一种由吲哚与7-氧杂双环[2.2.1]hept-5-en-2-one及其无芳环衍生物反应合成邻-双(3-吲哚基)芳烃的方法。所有 23 种未知的o -bis(3-indolyl)arenes 都可以使用这种方法获得。钯催化可用于扩大o -双(3-吲哚基)芳烃的 π- 共轭区域,提供芳基、炔基和烯基单元安装的o -双(3-吲哚基)芳烃和苯并 [ c ]吲哚[2,3- a ]咔唑类,衍生化可有效提高荧光量子产率。基于几项机理研究提出了一种可能的反应机理。
