Perfluoroalkyl sulfur compounds: An unusual reactivity pattern of perfluoroalkanesulfonic esters

Four kinds of perfluoro-or polyfluoroalkanesulfonic esters, namely RFSO3CH2RF, RFSO3CF2RF, RFSO3C6F5 and C6Fsub

Perfluoro- and Polyfluoro-sulphonic Acids. Part 22. Polyfluorophenyl Pentafluorobenzenesulphonates and their Electron Transfer Reaction with Sodium Iodide

Polyfluorophenyl pentafluorobenzenesulphonates (1) have been synthesized in excellent yields by the reaction of pentafluorobenzenesulphonyl chloride with polyfluorophenoxides.Nucleophilic attack on 1 resulted in the breakage of the S-O bond accompanied by displacement of o- and /or p-fluorine.Reaction of 1 with sodium iodide (8) in a mole ratio of 1:3 (1:8) yielded polyfluorodiphenyl ethers 9 and 10 as the main products.However, p-C6F5OC6F4SO3C6F5 (12) was isolated as the major product in addition to 9 and 10 when the reactant ratio was 1:1 or 1:0.25.Reaction of 12 with sodium iodide also gave 9 and 10 when the reactant ratio was 1:3 (12:8).The reaction of 1 (or 12) with NaI is supposed to be an electron-transfer process.
