A template consisting of a melamine‐based microporous polymer network was synthesized and utilized as a solid support to stabilize palladium nanoparticles; the resulting Pd/SNW1 material showed good catalytic activity in copper‐free Sonogashira coupling in water. Various aryl iodides were efficiently coupled with arylacetylenes under very low catalyst loadings in an environmentally benign medium. Hot
合成了由基于
三聚氰胺的微孔聚合物网络组成的模板,并将其用作稳定
钯纳米颗粒的固体载体。所得的Pd / SNW1材料在
水中的无
铜Sonogashira偶联中显示出良好的催化活性。在环境友好的介质中,在极低的催化剂负载下,各种芳基
碘化物可以有效地与芳基
乙炔偶联。热过滤测试证实了催化剂的非均质性,该催化剂在优化的条件下可以重复使用,其活性没有任何显着变化。催化剂的这种简单制备,催化剂的稳定性,产物的选择性以及易于回收和再生表明该催化剂体系在多种催化反应和工业过程中的可能利用。
