This article describes the invention of a class of effective reagents [(phen)2Cu](O2CRF) (1) for the decarboxylative perfluoroalkylation of aryl and heteroaryl halides. Treatment of copper tert-butyloxide with phenanthroline ligands, with subsequent addition of perfluorocarboxylic acids afforded air-stable copper(i) perfluorocarboxylato complexes 1. These complexes reacted with a variety of aryl and heteroaryl halides to form perfluoroalkyl(hetero)arenes in moderate to high yields. Computational studies suggested that the coordination of the second phen ligand may reduce the energy barrier for the decarboxylation of perfluorocarboxylate to facilitate perfluoroalkylation.

The action of silver fluoride on C3F7Fe(CO)4I in the presence of aromatic substrates (benzene, toluene, anisole, furan) at 20 deg C led to the formation of perfluoroalkylation products.On the basis of the isomeric composition of the obtained perfluoropropyl derivatives of toluene and anisole it was concluded that the process was cationic in nature.Perfluoropropyltoluenes were obtained when C3F7Fe(CO)4OCOCF3 or (C3F7)2Fe(CO)4 were heated in toluene.The cationic complex +BF4- reacts with dimethylaniline and with sodium p-toluenethiolate to form p-perfluoropropyldimethylaniline and p-tolyl perfluoropropyl sulfide.
