Abstract:Herein, we report a concise, effective and scalable strategy that the introduction of polar molecules (PMs) (e.g., anisole (PhOMe), phenetole (PhOEt), 2‐methoxynaphthalene (NaphOMe), thioanisole (PhSMe), and N,N‐dimethylaniline (PhNMe2)) as continuously coordinated neutral ligand of cationic active species in‐situ generated from the CGC‐type rare‐earth metal complexes A–F/AliBu3/[Ph3C][B(C6F5)4] ternary systems can easily switch the regio‐ and stereoselectivity of the polymerization of conjugated dienes (CDs, … Show more
