  摘要：

  摘要 研究了（多）卤代苯磺酰氯与烯烃的钯催化脱硫Heck型反应。发现在溴或碘苯磺酰氯存在下，苯乙烯或丙烯酸酯和无膦的钯催化剂可提供具有完全区域和立体选择性的预期的β-芳基化的Heck型产物。该反应可耐受卤代苯磺酰氯上的各种取代基。此外，在这些反应过程中未观察到C–Br和C–I键的裂解，从而允许进一步转化。使用4-溴苯磺酰氯作为中心单元，连续的脱硫Heck型反应，然后由钯催化的直接芳基化仅需两个步骤即可制备杂芳基二苯乙烯衍生物。 研究了（多）卤代苯磺酰氯与烯烃的钯催化脱硫Heck型反应。发现在溴或碘苯磺酰氯存在下，苯乙烯或丙烯酸酯和无膦的钯催化剂可提供具有完全区域和立体选择性的预期的β-芳基化的Heck型产物。该反应可耐受卤代苯磺酰氯上的各种取代基。此外，在这些反应过程中未观察到C–Br和C–I键的裂解，从而允许进一步转化。使用4-溴苯磺酰氯作为中心单元，连续的脱硫Heck型反应，然后由钯催
