from benzenesulfonyl chlorides and alkenes is described. Under acidic condition, a wide range of β-alkoxy sulfides were obtained in good to excellent yields, whereas under alkaline conditions, various vinyl sulfones were produced in moderate to good yields. A novel preparation of (E)-β-iodovinyl sulfones was achieved through direct difunctionalization of alkynes with benzenesulfonyl chlorides and TBAI
描述了四丁基碘化铵 (TBAI) 促进从苯磺酰氯和烯烃生成含硫化合物。在酸性条件下,以良好到极好的收率获得了广泛的 β-烷氧基硫化物,而在碱性条件下,以中等至良好的收率生产了各种乙烯基砜。通过炔烃与苯磺酰氯和 TBAI 的直接双官能化,实现了 (E)-β-碘乙烯基砜的新制备。
