Progress in [¹⁸F]Fluorination by Using Aryliodonium(III) Compounds and Application for PET Tracer Syntheses

[¹⁸F]-labeled drugs and radioligands are most frequently used in positron-emission tomography (PET) radiopharmaceuticals for both clinical and preclinical research. Various methods for the introduction of [¹⁸F]fluorine into complex molecules through fluorination reactions have been reported. Herein, recent advances in [¹⁸F]-fluorination utilizing aryliodonium(III) compounds are highlighted.
