In this manuscript, the influence of the position of the alkoxy‐substituents on the polymerization of poly(phenylenes) is investigated. For this purpose, 3‐alkoxy‐ m ‐phenylene is polymerized using the Kumada catalyst transfer condensative polymerization. Three different catalyst systems are tried, which all resulted in polymer, but with a high dispersity. Additional experiments show that the polymerization proceeds via a noncontrolled chain growth mechanism.
