Abstract :
The addition of radical scavengers to the fluoridation of diaryliodonium salts was demonstrated to improve significantly both the reproducibility of the process and the material yield of the desired fluoroarene products. It was also established that the selectivity of the process was not influenced by the presence of the radical scavengers. TEMPO and galvinoxyl were found to be the most suitable radical scavengers in the fluoridation process allowing the methodology to be used routinely for the first time.
