we reported the heterogeneousphotocatalyticC–H alkylation of indoles with diazo compounds using graphitic carbonnitride (g-C3N4) as the photocatalyst. The reaction was carried out under a simple operation and mild conditions. In addition, the catalyst was found to be stable and reusable after five reaction cycles. The photochemical reaction proceeds via an intermediary of a carbon radical, which
在此,我们报道了使用石墨氮化碳(gC 3 N 4)作为光催化剂,吲哚与重氮化合物的非均相光催化C-H烷基化反应。该反应操作简单,条件温和。此外,发现该催化剂在五个反应循环后稳定且可重复使用。光化学反应通过碳自由基的中介进行,碳自由基是通过可见光促进的质子耦合电子转移(PCET)过程从重氮化合物产生的。
