The rapid and operationally simple radiosynthesis of branched allylic [18F]fluorides bearing a variety of functional groups, via iridium-catalyzed nucleophilic substitution reaction utilizing allylic trichloroacetimidates and [18F]KF·Kryptofix[2.2.2] complex in 5–15 min at room temperature, is reported. The versatility of the allyl functional group of the resulting radiofluorinated products offers the benefit of being subsequently available for further functionalization.
