ABSTRACT
We report that halogenophilic silver(I) triflate permits halogen exchange (halex) nucleophilic (18)F-fluorination of aryl-OCHFCl, -OCF2Br and -SCF2Br precursors under mild conditions. This Ag(I)-mediated process allows for the first time access to a range of (18)F-labeled aryl-OCHF2, -OCF3 and -SCF3 derivatives, inclusive of [(18)F]riluzole. The (18)F-labeling of these medicinally important motifs expands the radiochemical space available for PET applications.
