Thioetherification reaction of aryl iodides catalysed by palladium(II) complexes in the presence of 1,3,5-trithiane as sulphur source is reported. The paper presents the first homogeneous catalytic application of 1,3,5-trithiane in synthesis. Detailed optimization steps, the frames of the novel reaction are described, as well as the limitations and the substrate scope are also demonstrated. Moderate
报道了在 1,3,5-三噻烷作为硫源存在下由钯 (II) 配合物催化的芳基碘化物的硫醚化反应。该论文首次介绍了 1,3,5-三噻烷在合成中的均相催化应用。描述了详细的优化步骤、新反应的框架,以及局限性和底物范围。在各种取代的碘苯和一些链烯基碘的存在下,使用钯-黄原磷催化剂体系,实现了中等至良好的硫醚产率。还进行了混合底物存在下的竞争反应,并假设了机械方面的考虑。
