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。

The mild and readily available Cu(NO3)2 mediated ortho nitration of anilides with broad substrate using K2S2O8 as an oxidant in the absence of any other metal catalyst and nitrating agent under mild conditions was reported for the first time.
首次报道了在温和的条件下,在没有任何其他金属催化剂和硝化剂的情况下,使用K 2 S 2 O 8作为氧化剂,温和且容易获得的Cu(NO 3)2介导的苯胺与宽底物的邻位硝化。
