Visible-Light-Induced C(sp3)-H Oxidative Arylation with Heteroarenes.

Considering the ubiquitous C(sp3)-H and the important value of alkylated heteroarenes, developing a universal method for C(sp3)-H arylation with heteroarenes is significant. Herein, we proposed a method where Selectfluor can promote the oxidative C(sp3)-H arylation with heteroarenes without external photocatalysis under visible-light irradiation. By EPR study, the N-F activation of Selectfluor by blue LED irradiation can generate the N radical cation, which is the key step for this conversion.
