Synthesis Of Mcm-41 Supported Amino-Palladium Complex And Its Catalytic Performance For Heck Reaction

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 coordinates 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 similar to 90 degrees C. The product of Heck reaction takes E form. And the effect of the preparation condition of the catalyst on the catalytic performance was examined.
