catalyst deactivation and deleterious side reactions. Herein, we report a copper(II)-mediated C(sp2)–H amination of benzamides with electronically neutral or electron-rich anilines. A dramatic influence of silver(I) and tetrabutylammonium bromide was observed on the reaction outcome. The present protocol also demonstrates the synthesis of a number of nonsteroidal anti-inflammatory drugs.
尽管取得了重大进展,但由于催化剂失活和有害的副反应,
铜催化/介导的CH-H与富电子
苯胺的胺化反应仍未解决。在这里,我们报告了苯甲酰胺与电子中性或富电子
苯胺的
