【Abstract】 A organic/silica hybrid material surpported palladium catalyst is studied.Using the reaction between iodobenzene and acrylic acid as a model,the activity of this catalyst is studied.The effect of different reaction conditions on the yield are investigated.The result shows that the catalyst has high catalytic activity and regionselectivity for the synthesis of trans-phenylacrylic acid.The catalyst can be recovered by filtration and washing with solvent,and reused for many times.The Heck arylation reactions of other substrates catalyzed by the catalyst also investigated.更多还原
