Photoredox-catalyzed fluorodifluoroacetylation of alkenes with FSO 2 CF 2 CO 2 Me and Et 3 N·3HF.

Photoredox-catalyzed three-component fluorodifluoroacetylation of aromatic alkenes is reported, which features a wide substrate scope and functional group tolerance. An advantage of the reaction is the use of a nucleophilic fluoride source and a general difluoroacetylation reagent for the fluorodifluoroacetylation of alkenes.
