Copper-Catalyzed Direct Nitration on Aryl C-H Bonds by Concomitant Azidation-Oxidation with TMS Azide and TBHP under Aerobic Conditions

Vinayak, Botla,Chandrasekharam, Malapaka

, p. 3528 - 3531 (2017)

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.
