Reactions of propargylic bromides with sodium sulfinates

A one-pot, palladium-catalyzed synthesis of substituted 2,3-bissulfonylpropenes starting with propargylic bromides 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.

-Sigmatropic Rearrangement of β-Phenylsulfonyl Propargylic Sulfenates as a Method for Preparing 1,4-Bis(phenylsulfonyl)-1,3-butadienes

Several β-sulfoxy-substituted acetylenic carbinols were prepared by the addition of thiyl radicals and oxygen to conjugated enynes.The products obtained are derived from thiyl radical attack at the olefinic bond to generate a propargylic radical.Capture o
