Catalytic Azido‐Hydrazination of Alkenes Enabled by Visible Light: Mechanistic Studies and Synthetic Applications

A visible‐light‐enabled catalytic intermolecular azido‐hydrazination method for unactivated alkenes is developed via an orderly radical addition sequence. This transformation features metal‐free and redox‐neutral conditions and is applicable to a wide range of alkenes with commercially available reagents. Mechanistic and kinetic studies reveal that the efficient generation of azide radical enabled by fluorenone under visible‐light is critical to...
