An efficient palladium-catalyzed coupling reaction of aryl bromides with butyl methacrylate has been developed. Depending on the reaction conditions various amounts of butyl 3-aryl-2-methylpropenoate and butyl 3-aryl-2-methyliden-propenoate as well as double arylated products were produced. Superior turn over numbers up to 8300 and turn over frequencies up to 1000 h -1 for Heck reactions of aryl bromides with methacrylic acid ester have been obtained for the first time.
