Direct C(sp2)–H bond functionalization of indoles with arylboronic acids is achieved using palladium supported on carbon as a reusable heterogeneous catalyst in the presence of an oxidant under mild conditions. The current protocol formed exclusive C-2 selective products without the aid of any ligand or directing group. The catalyst is reusable for up to four catalytic cycles with the retention of catalytic efficiency.

直接的C–H键活化:碳钯作为可重复使用的异质催化剂,用于吲哚与芳基硼酸的C-2芳基化

在温和条件下,在氧化剂存在下,使用负载在碳上的钯作为可重复使用的多相催化剂,可以实现吲哚与芳基硼酸的直接C(sp 2)–H键官能化。目前的方案在没有任何配体或指导基团的帮助下形成了排他的C-2选择性产物。该催化剂可重复使用多达四个催化循环,同时保持催化效率。
