A copper-catalyzed annulative amination approach to 3-aminobenzofurans and -indoles from o-alkynylphenols and -anilines has been developed. The Cu-based catalysis is based on an umpolung, electrophilic amination with O-benzoyl hydroxylamines and enables t

A copper-catalyzed electrophilic, umpolung amination strategy for the direct C-H amination of polyfluoroarenes and 1,3-azoles has been developed. The copper-based amination reaction is robust and can be easily scaled up on a gram scale. Its application to
