A ruthenium photocatalyst mediates a synthesis of 3-fluoroindoles from N-arylamines substituted with the CF₂I group in the presence of a substoichiometric amount of triphenylphosphine upon irradiation with blue light. The starting N-arylamines are readily obtained by nucleophilic iododifluoromethylation of iminium ions.
