A one-pot, palladium-catalyzed synthesis of substituted 2,3-bissulfonylpropenes starting with propargylicbromides and sodium sulfinates (RSO2Na) in the presence of n-Bu4NF under refluxing aqueous 1,4-dioxane conditions for eight hours in moderate yields is described.

mixture of dioctenyl sulphoxides by way of alkenesulphenic acid–dialkyl sulphine interconversions. Benzenesulphenic acid, methanesulphenic acid, and ethoxycarbonylmethanesulphenic acid, conveniently generated by thermolysis of 1-cyano-2-alkyl(or aryl)sulphinylethanes, underwent intermolecular addition to unactivated and activated alkynes regioselectively to give alkenyl sulphoxides in good yields.
