    Site-selective installation of fluorine (19F) and its radioisotope (18F) in aromatic molecules can lead to high-value products, but methods for this purpose are not without limitations. Now, using photochemistry, a 19F- and 18F- labelling strategy is reported that complements traditional approaches.
