摘要：

Sesbania gum supported palladium compound was synthesized with simple method and characterized by XPS, IR, TG, DTA, TEM etc. It was found that the sesbania gum supported palladium compound is an efficient catalyst for Heck reaction of acrylic acid, styrene and acrylamide with aryl iodide such as iodobenzene, 4-iodotoluene, 4-iodoanisole, 1-chloro-4-iodobenzene at atmospheric condition. The substituted trans-cinnamic acid, trans-stilbene and trans-cinnamoylamide was obtained in high yield (>= 85 %). The sesbania gum supported palladium compound can be used repeatedly in the Heck reaction. The active center of the catalyst is metallic Pd.
