## Abstract A polymer‐supported macrocyclic Schiff base palladium complex has been synthesized. In the Heck reaction of aryl iodides and bromides with ethyl acrylate or styrene, the complex has been proved to give the corresponding products in good to excellent yields. The reaction proceeded smooth
Two kinds of polyvinyl chloride-polyethylene-polyamine supported palladium complexes were synthesized and characterized by XPS, TG, DTA, TEM, etc. These complexes are efficient catalysts for Heck reaction of acrylic acid with aryl iodides in air at the low temperature (50 • C) using 0.125 mol% of th
