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

Sulfenic esters of β-sulfur substituted acetylenic carbinols undergo 2,3-sigmatropic rearrangement to produce allenylic sulfoxides which were converted to 1,4-bis(phenylsulfonyl)-1,3-dienes of α,β-unsaturated ketones.
