The scope and limitations of Pd(0)-mediated coupling reactions between aromatic halides linked to a polystyrene resin and boronic acid derivatives (Suzuki coupling), aromatic and vinylic tin compounds (Stille coupling), as well as thiols are reported. For all reactions, conditions were optimized and evaluated with various reagents. In many cases, upon cleavage from the solid support, products were obtained in excellent yields. In most cases, the optimized reaction conditions are superior to those previously reported in the literature.
本文报道了零价钯催化的芳基卤代物与聚苯乙烯树脂相连的配体、硼酸衍生物(铃木偶联反应)、芳基和乙烯基锡化合物(斯蒂尔偶联反应)以及硫醇之间的偶联反应的范围和局限性。针对所有反应,经过优化条件并使用不同试剂进行评估。在许多情况下,从固相载体上切割下来的产物收率极佳。大多数情况下,经过优化的反应条件优于先前文献报道的条件。
