Figure 1. The direct arylation of allylic C–H bonds via the synergistic merger of photoredox and organic catalysis.
Arylation of allylic bonds is generally accomplished via transition metal-catalyzed couplings with pre-functionalized substrates (a). Installation of heteroatoms via direct allylic C–H functionalization is widely precedented (b). Direct C–H arylation is proposed via the synergistic merger of photoredox and organic catalysis (c).
