Abstract: | Readily accessible and easy‐to‐handle Ru complexes capable of generating all‐Z polynorbornene and polynorbornadiene by ring‐opening metathesis polymerization (ROMP) with controllable selectivity, ranging from ≈50 to ≥95 % syndiotactic, are introduced. It is demonstrated that the rate of non‐metathesis based polytopal isomerization and levels of syndiotacticity may be fine‐tuned by the adjustment of monomer concentration and catalyst's steric and electronic characteristics. |
