Abstract
Perfluoroalkyl sulfides are prepared by reaction of perfluoroalkyl halides with disulfides in the presence of sulfoxylate anion radical precursors. Aliphatic, aromatic and heteroaromatic disulfides bearing cyano, ester and amino functional groups have been employed; a variety of perhalogenoalkanes can also be employed, e.g. CF3(CF2)nI, CF3Br, CF2Br2, CF2BrCl, CFCl3 and CF2ClCFCl2. The most convenient sulfoxylate anion radical precursor for this reaction is formed by a combination of sodium formate and sulfur dioxide.Keywords
