4‐oxadiazoles using alkylhalides as precursors of radicals is described. The reaction efficiency is determined by potassium tetrafluoropyridinyl thiolate additive, which plays dual role. First, the thiolate converts alkylhalides into more reactive fluorinated aryl sulfides, which undergo photoredox activation of the C‐S bond. Second, the thiolate decreases the unproductive loss of alkyl radicals by converting
