Visible-light-promoted azidation/arylation of unactivated alkenes with Togni-N3via electron donor–acceptor complexes

A visible-light-promoted azidation/arylation of unactivated alkenes with Togni-N₃ has been achieved, leading to a series of azidated pyrrolo[1,2-a]indoles under photocatalyst-free conditions. Notably, an EDA complex derived from the electron-rich indole derivatives and Togni-N₃ served as the key intermediate in this reaction.
