摘要：

A hollow magnetic mesoporous silica sphere (HMMS) catalyst has been synthesized using polystyrene microspheres as a chemical template. The catalyst was characterized by TEM, XRD, XPS and vibrating sample magnetometry (VSM). The catalyst shows high activity for the carbonylative cross-coupling reaction of aryl iodides with arylboronic acids and Suzuki coupling reactions. The newly developed catalyst is easy to recover by magnetic separation from the liquid phase of the reaction and can be recycled. Importantly, the catalyst revealed high efficiency and high stability under the reaction conditions and during recycling stages.
