Alumina‐mediated CF activation (AmCFA) is an established method to generate incipient phenyl cation (IPC) through polarization of C(aryl)F bonds. Herein, it is reported that AmCFA can be used to induce intramolecular arylation of aryl alkynes containing one, two, and three triple bonds. During the reaction, a single formally eliminated hydrogen fluoride (HF) leads to the formation of two, three, and four CC bonds, respectively. Thus, the transformation gives rapid access to π‐extension and serves as an interesting example of solid‐state rational domino annulation enabling the bottom‐up construction of nanographenes.

氧化铝介导的C ?引起芳基炔烃的级联 F键激活
氧化铝-体介导C ˚F活化(AmCFA)是生成通过C(芳基)的极化初始苯基阳离子(IPC)已建立的方法 F键。在此,据报道,AmCFA可用于诱导包含1、2和3个三键的芳基炔烃的分子内芳基化。在反应过程中,一个正式消除的氟化氢(HF)分别导致形成两个,三个和四个CC键。因此,该变换可快速访问π延伸,并成为固态有理多米诺环化的有趣示例,可实现纳米级石墨烯的自底向上构造。
