Merging σ‐Bond Metathesis with Polymerization Catalysis: Insights into Rare‐Earth Metal Complexes, End‐Group Functionalization, and Application Prospects

open access: yesMacromolecular Rapid Communications, Volume 45, Issue 15, August 2024.
Current research optimizes metal‐catalyzed synthesis of well‐defined polymers with distinct end groups, serving as fundamental building blocks for functional materials. Investigations combine coordination polymerization with rare‐earth metal complexes and C–H bond activation via σ‐bond metathesis, allowing precise control over end‐group functionalities.
