Vinyl sulphones desulphonylation

The reagent has also been used to desulphonylate vinyl sulphones to give alkenes141-143. The solvent was refluxing 10% aqueous THF and the yields reported were over 80%. 

Details of the conditions used in these reductions are discussed, especially the fact that this is apparently the first example in which the stereochemical aspects of an electrochemical desulphonylation reaction on a complex molecule have been examined. It is likely that further work will be profitable, given suitable substituents on a molecule, since sulphones (especially vinyl and aryl sulphones) should be good candidates for this type of reduction.
