1,3-Dienes react with CO2 at ligand-iron(0) systems to form η3-allyl carboxylates. The dynamic allylic system is influenced by addition of further ligands such as phosphanes or maleic acid anhydride or acetic acid anhydride. The direction of this influence is shown on the basis of the products generated by protonolysis or insertion of CO2. When substituted 1,3-dienes are used, the 1/1 coupling step
