Abstract
Process for the preparation of an alkyl pentenoate respectively an aryl pentenoate by contacting an alkoxy-butene respectively an aryloxy-butene compound with carbon monoxide in the presence of a catalyst system comprising palladium, a phosphorus ligand and an acid promotor, wherein the molar ratio of 3-alkoxy-1-butene to 1-alkoxy-2-butene, respectively the molar ratio of 3-aryloxy-1-butene to 1-aryloxy-2-butene, is higher than 4.
