synthesis of vinyl sulfoxides, using sulfinyl chlorides and olefins as starting materials and DBU as an HCl scavenger, has been developed. Vinyl sulfoxides were obtained from the ZnCl2 catalysed addition of sulfinyl chlorides to olefins followed by the elimination with DBU. However, the direct reaction of sulfinyl chlorides with olefins in the presence of DBU, usually leads to generation of vinyl sulfones

Abstract A novel reaction of trimethylsilylated arylacetylenes with sulfonyl chlorides was performed in the presence of silver nitrate or triflate. Conjugated vinyl sulfones as dramatic products were obtained in moderate yields and with Z -selectivity. A free radical mechanism has been proposed to account for the formation of the products.
