Herein, we describe an efficient, practical photocatalytic deoxygenation/defluorination protocol for the synthesis of γ,γ-difluoroallylic ketones from commercially available aromatic carboxylic acids, triphenylphosphine, and α-trifluoromethyl alkenes. The protocol has good functional group tolerance and a broad substrate scope. Using this method, we accomplished the late-stage functionalization of several bioactive molecules.
