摘要：

Silica-supported palladium (0) complexes have been prepared from γ-chloropropyl triethoxysilica and γ-aminopropyl triethoxysilica via immobilization on fumed silica, followed by reacting with ethylenediamine and salicylaldehyde, and then the reaction with palladium chloride in ethanol and reduction with KBH4 in ethanol. They are efficient catalysts for Heck reaction of aryl iodides with alkene at 90oC. These polymeric palladium (0) catalysts can be recovered and reused without loss in activity.
