[18F]F-DOPA is an important radiotracer that is used in the diagnosis of Parkinson's disease and neuroendocrine tumours. We describe a simple synthesis for a number of diaryliodonium salt precursors that are suitable for the production of [18F]F-DOPA through reaction with no carrier added (n.c.a.) nucleophilic [18F]fluoride. The simple procedure gives bench-stable, complex iodonium precursors in good yields without the need for laborious anhydrous conditions. Further alteration to the precursor counterion can be readily achieved for a range of halides and pseudo halides by a simple modification of the workup. Preliminary “hot” and “cold” fluorination results show the suitability of the compounds for the production of [18F]F-DOPA.
