Efficient Polymer-Supported Pd Catalysts for the Heck Reaction

Some efficient polymer‐supported palladium catalysts have been synthesized. Their catalytic effects were evaluated in the Heck reaction of iodobenzene with acrylates or styrene. High catalytic activities were achieved with turn over frequencies (TOF) up to 28000 and 6250, respectively. For the reaction of iodobenzene with styrene, high stereoselectivity was obtained. Additionally, the catalysts could be recovered by a simple filtration progress and can be reused for at least 5 times with a slow progressive decrease in activity.
