Abstract
Small aromatics such as anthracene, naphthalene, or benzene bearing two diarylamino
termini function as highly reducing organic photocatalysts (OPCs). In particular,
the small aromatic core remarkably enhances the reducing power of the catalyst in
the excited state. An appropriate combination of an OPC and an electron-accepting
fluoroalkylating reagent is the key to successful radical fluoroalkylation. The basic
design of the photocatalyst and the photocatalytic fluoroalkylation of olefins are
discussed.
