A thiol-free procedure for regioselective preparation of (Z)-β-alkenyl sulfides via a three-component reaction of aryl/alkyl halides, phenylacetylene, and potassium isopropylxanthate in the presence of copper iodide as a catalyst in polyethylene glycol is reported. In this study, a xanthate salt is used as an odorless source of sulfur. The reactions proceed in a one-pot and single-step pathway with
报道了在碘化铜作为催化剂的聚乙二醇存在下,通过芳基/烷基卤化物、苯乙炔和异丙基黄原酸钾的三组分反应,无硫醇区域选择性制备( Z )-β-烯基硫醚的方法。在这项研究中,黄原酸盐被用作无味的硫源。该反应以一锅单步途径进行,形成使用 NMR 数据鉴定的碳酸氢盐中间体,并专门形成Z异构体。
