Solid‐Supported Iodonium Salts for Fluorinations

Solid‐supported iodonium salt precursors have been prepared and used for the production of fluoroarenes. The importance of the resin functionality for the attachment of the iodonium salt moieties has been demonstrated. Furthermore, the production of new iodonium salt precursors for fluorination has been achieved by an alternative and improved method with respect to those previously described. The successful radiofluorination of a simple solid‐supported precursor with no‐carrier‐added (n.c.a.) [ 18 F]fluoride shows the suitability of the method for the production of useful PET synthons.
