摘要
In the past decades,diazaphospholene hydrides(DAP-H)have emerged as powerful catalysts for a variety of reductive transformations.However,the radical processes with DAPs as catalysts are extremely rare.Herein,a DAP-catalyzed radical process of aryl halides to accessγ-spirolactams through a XAT/1,5-HAT/radical addition/HAT process is presented.This reaction features metal-free conditions and broad functional group tolerance,leading toγ-spirolactams in good yields.
