Using MCM-41 as supporter, a series of MCM-41 supported amino-palladium complexes have been prepared and characterized by XRD, XPS, etc. The XRD and XPS results indicate that the Pd coordi-nates with the NH2 groups on the MCM-41 surface, and the structure of MCM-41 has been not damaged. Its catalytic performance for Heck arylation of alkene with aryl iodide shows that the catalyst has high activity and stereoselectivity in 70~90 ℃. The product of Heck reaction takes E form. And the effect of the preparation condition of the catalyst on the catalytic performance was examined.

Key words: palladium complex, heterogeneous catalyst, Heck reaction, MCM-41
