摘　　要：报道银(Ⅰ)催化芳香端炔与磺酰氯的新颖反应.该反应出乎意料地得到烯基砜,产率47%～72%,并且具有Z选择性.提出了自由基催化循环机理,解释了烯基砜的形成及烯基砜的立体化学结果.A novel reaction of terminal arylacetylenes with sulfonyl chlorides was performed in the presence of a silver（I） catalyst. Vinyl sulfones were obtained in 47%-72% yields. A fi＇ee radical mechanism for the catalytic cycle has been pro- posed to account for the formation of products and the stereochemical outcome of vinyl sulfones.
