Abstract
A process for the perfluoroalkylation of aromatic derivatives. In a first stage, an aromatic derivative, sulfur dioxide and a metal selected from the group consisting of zinc, aluminum, manganese, cadmium, magnesium, tin, iron, nickel and cobalt, are brought into contact in a solvent, preferably a polar aprotic solvent. In a second stage, a perfluoroalkyl bromide or iodide is added to react with the aromatic derivative.
