报道一种在纯水中Pd/C催化的高效Suzuki反应体系,该体系无需除氧,且无外加配体和添加剂,底物普适性广泛,含有亲水或疏水基团的溴代芳烃都能被高效活化.此外,对部分杂环芳烃与芳基硼酸的偶联反应也有较好的催化效果.该催化剂可高效循环使用三次,且性能无明显下降.
An efficient Suzuki reaction catalyzed by Pd / C in pure water is reported. The system has no need of oxygen scavenging and no external ligands and additives. The substrate has a wide universality and all of brominated aromatic hydrocarbons containing hydrophilic or hydrophobic groups Can be efficiently activated.In addition, the coupling reaction of some heterocyclic aromatic hydrocarbon and arylboronic acid also has a good catalytic effect.The catalyst can be efficiently recycled three times without any significant decrease in performance.
