Just add light and air: Structurally diverse N‐arylindoles can be prepared from readily prepared o‐styryl anilines through visible‐light photocatalysis. The reaction, which is conducted open to air, is mediated by [Ru(bpz)3](PF6)2 (bpz=2,2′‐bipyrazine) and involves both CN bond formation and aromatization (see scheme). Using suitably substituted substrates, a 1,2‐carbon shift can be also incorporated
只需添加光和空气:可以通过可见光光催化从容易制备的邻苯乙烯基苯胺制备结构多样的N-芳基吲哚。该反应在空气中进行,由 [Ru(bpz) 3 ](PF 6 ) 2 (bpz=2,2′-联吡嗪)介导,涉及 C N 键形成和芳构化(见方案)。使用适当取代的底物,1,2-碳转移也可以纳入该级联反应中。
