A new intermolecular, stereo- and regioselective iron-catalyzed 1,4-addition of α-olefins to 1,3-dienes using as low as 1 mol % of an iminopyridine−ferrous chloride complex was developed. Importantly, both double bonds of the linear 1,4-diene addition products are obtained with absolute stereocontrol.
Provided are methods of preparing polymers, such as polyisoprene, polybutadiene, polypiperylene, polycyclohexadiene, poly-β-farnesene, or poly-β-myrcene, using iron complexes. Also provided are novel iron complexes, pre-catalysts, intermediates, and ligands useful in the inventive polymerization system.
