Fluorine-18 labelled arenes and heteroarenes are an important class of substrates in medical imaging by positron emission tomography (PET). Traditionally, these molecules are prepared via nucleophilic aromatic substitution (SNAr) reactions of an appropriately activated substrate, which limits the scope of molecules that can be radiolabelled with [18F]fluoride. This presentation will discuss an alternative methodology that employs the use of spirocyclic hypervalent iodine(III)-complexes for the efficient one-step labelling of a broad range of non-activated functionalized arenes and heteroarenes. The application of this methodology towards preclinical and clinical research will be discussed.
