Azidofluoroalkylation of Alkenes with Simple Fluoroalkyl Iodides Enabled by Photoredox Catalysis.

A mild and efficient protocol for photoredox-catalyzed azidofluoroalkylation of simple alkenes is described with readily available fluoroalkyl iodides. This method allows for a direct and regioselective formation of C-RF and C-N3 bonds from the C═C moiety. A variety of fluoroalkyl groups including the CF3 group can be selectively introduced to olefins to afford a series of β-fluoroalkylated azides.
