Catalytic Properties of Carbon Supported Pd/Ce Bimetallic Catalyst on Heck Reaction
Carbon supported Pd/Ce bimetallic catalyst was prepared readily for Heck reaction.The effect of reaction conditions on the catalytic properties of carbon supported Pd/Ce bimetallic catalyst was studied in details with the model Heck reaction of iodobenzene and acrylic acid.The results show that carbon supported Pd/Ce bimetallic catalyst can effectively catalyze the Heck reactions under the conditions of 130 ℃,5 h,DMF as the solvent,and Bu3N as the base to afford the product with a yield of over 70％.Additionally,the heterogeneous carbon supported Pd/Ce bimetallic catalyst can be easily separated from the reaction solution.Furthermore,the catalyst can be reused for 3 times with a yield of 69％ and without the significant loss of catalytic efficiency.
