A novel dehydrogenative dicarbofunctionalization of vinyl arenes with polyfluoroarenes and unactivated alkanes enabled by copper catalysis has been accomplished under mild conditions. This transformation provides a regioselective route to highly functionalized polyfluoroaryl compounds that occur as structural scaffolds in a variety of pharmaceuticals and materials. Preliminary mechanistic studies indicate that the carbon-based radical and copper intermediate are involved in the reaction, and the reaction pathway is dominated by the bond dissociation energy (BDE) of C(sp3)-H bonds.
