Highly active with ultrafast initiation, the catalyst 1 promotes the controlled, living, ring‐opening polymerization of various norbornene and 7‐oxonorbornene derivatives (see scheme). The high k i / k p ratio associated with the polymerization reactions results in better molecular‐weight control and narrower polydispersity indexes (PDIs, k i =rate constant for initiation, k p =rate constant for polymerization).
