An unprecedented copper-catalyzed in situ azidation–oxidation for the nitration of anilides and sulfonamides has been developed by direct CAr–H functionalization. This novel and efficient nitration protocol is achieved employing TMSN3 and TBHP without the exclusion of air or moisture. The synthetic applications of the 2-nitroanilides have been explored.
通过直接的C Ar -H功能化,开发出了前所未有的铜催化原位叠氮化氧化技术,用于苯胺和磺酰胺的硝化。使用TMSN 3和TBHP可以实现这种新颖而高效的硝化方案,而不会排除空气或湿气。已经研究了2-硝基苯胺的合成应用。
