Visible light promoted fluoroalkylation of alkenes and alkynes using 2-bromophenol as a catalyst

We report a new protocol for the fluoroalkylation of alkenes and alkynes by using 2-bromophenol as a catalyst. This reaction can be tailored for different reaction modes by altering the base and solvent, which feature a wide substrate scope and excellent functional group tolerance with high chemo- and regioselectivities. We further propose a mechanism involving an electron donor-acceptor (EDA) complex.
