Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flowsystem, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3CO2K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3] sources.
