A mild two-step synthesis of perfluoroalkanesulfonyl chlorides starting from perfluoroalkyl iodides has been developed. Reaction of perfluoroalkyl iodides with sodium dithionite gave sodium perfluoroalkanesulfinate salts which were converted into perfluoroalkanesulfonyl chlorides in 25-73% yield (two steps) using N-chlorosuccinimide.

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.
Process for the preparation of perhaloalkylthioethers

, (2008/06/13)
The present invention relates to a process for the preparation of perhaloalkylthioethers by bringing a perhaloalkyl halide, preferably a bromide or an iodide, into contact with a disulphide in the presence of zinc and of sulphur dioxide or of a dithionite or of a hydroxymethanesulphinate or of a formate anion and sulphur dioxide.
