The reaction of three moles of vinylmagnesium bromide with one mole of nitroarene leads to the formation of indoles after aqueous work up of the mixture. Good yields are obtained with ortho-substituted nitroarenes.
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。
