The Cu(I)-catalyzed pentafluoroethylation of iodoarenes via the fluorocupration of tetrafluoroethylene (TFE) is disclosed. The active species, (phen)CuC2F5, was isolated and its molecular structure confirmed by a single-crystal X-ray diffraction analysis. The key to the successful suppression of the competing oligomerization of TFE is to refrain from stirring the reaction mixture. A mechanistic study clearly discarded the possibility that the catalytic reaction proceeds via a radical pathway.

A method for the copper-catalyzed pentafluoroethylation of aryl iodides using potassium (pentafluoroethyl)trimethoxyborate has been developed. The borate was found to be a convenient pentafluoroethyl source. In parallel, it was found that the solvent, as well as ligand, makes significant impact on the catalytic perfluoroalkylations.
