A mild and practical protocol for selectively time-dependent dehydrogenative C-C coupling, as well as tandem coupling-cyclization reaction between indoles or/and other heteroaromatics via electrochemically oxidative process has been demonstrated. The reaction runs under noble catalyst, external oxidant and inert gas free condition, allowing tunable access to a wide variety of synthetically useful symmetrical
已经证明了一种温和实用的选择性时间依赖性脱氢 CC 偶联,以及吲哚或/和其他杂芳烃之间通过电化学氧化过程的串联偶联环化反应的方案。该反应在惰性催化剂、外部氧化剂和无惰性气体条件下进行,可调谐获得各种具有聚集诱导发射 (AIE) 的合成有用的对称或非对称杂芳烃,以及具有聚集引起猝灭的多环 3-D 吲哚衍生物(ACQ) 荧光特性。最后,初步的机理研究表明,在不同的电解电位下,通过调节N-保护基团是实现吲哚与其他杂芳烃交叉偶联的关键。
