Abstract
Perfluoroalkylthioethers are synthesized from disulfides and freons, halons or halogenoperfluoroalkanes according to: 2R FX + 2Red+ RSSR → 2R FSR + 20x This reaction was studied with aliphatic, aromatic and heteroaromatic disulfides Several reductor systems have been used. They behaved as sulfur dioxide-radical anion precursors. The initial step is interpreted by single electron transfer from this radical anion to the halide. The mechanism will be discussed. Halogenoalkylthioethers groups are very lipophilic and interesting as substituents for pharmaceutical drugs and agrochemical compounds.
