A bimetallic mesoporous system (Ni/Cu-MCM-41) has been developed and evaluated as an efficient catalyst for the Sonogashira cross-coupling reaction, under palladium-free conditions. In this new methodology, a wide range of aryl halides react with phenylacetylene to give the corresponding disubstituted alkynes in good yields. Moreover, the present catalytic system is desired because of its high efficiency, easy preparation, low cost, high activity, and good recyclability.

Ni / Cu双金属介孔二氧化硅纳米粒子作为Sonogashira交叉偶联反应的有效且可重复使用的催化剂

已经开发了双金属介孔体系（Ni / Cu-MCM-41），并作为无钯条件下Sonogashira交叉偶联反应的有效催化剂进行了评估。在这种新方法中，大量的芳基卤化物与苯乙炔反应，以高收率得到相应的二取代炔烃。而且，由于其高效，易于制备，低成本，高活性和良好的可回收性，因此需要本催化体系。
