Abstract

The treatment of commercially available polymethyl methacrylate (PMMA) microspheres with palladium (Pd)Cl₂ and formaldehyde, generated supported Pd(0)-PMMA with 0.79 (wt) % catalyst loading. The catalyst has been used for copperand ligand-free Sonogashira reactions in aqueous media. It is highly reactive for the reactions of iodobenzenes with aryl acetylenes or alkyl acetylenes. The performance of the recovered catalyst had no signifi cant difference in fi ve cycles. The Pd leaching was detected at a very low level (2.1 - 9.8 ppm) for each cycle. PMMA-supported PdCl₂, Pd(OAc)₂, PdCO₃, and PdCl₂ (MeCN)₂ have also been tested for Sonogashira reactions.
