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.

A copper-catalyzed decarboxylative trifluoromethylation of (hetero)aromatic iodides has been developed. Importantly, this new copper-catalyzed reaction operates in the absence of any ligands and metal additives. The protocol shows good functional group tolerance and is compatible with heteroaromatic systems. The reaction proved scalable to a 15 mmol scale with increased yield. Finally, late-stage installation
