Copper-catalyzed remote C(sp 3)–H azidation and oxidative trifluoromethylation of benzohydrazides
Abstract
Functionalization of carbon radicals formed via 1,5-hydrogen atom transfer of amidyl radicals is an underdeveloped protocol for remote C–H functionalization. Here, the authors report a Cu-catalyzed γ-azidation and oxidative δ-trifluoromethylation of benzohydrazides for the synthesis of more functionalized amides.
