Functionalizations of C─H and C═C Bonds in Polyolefins Catalyzed by Transition‐Metal Complexes

Angewandte Chemie Novit, Volume 1, Issue 2, October 2025.
Post‐polymerization modification of polyolefins is a powerful strategy to create otherwise inaccessible materials; transition‐metal‐catalyzed functionalizations of C─H and C═C bonds enable site‐, chemo‐, and stereoselective installation of groups to impart unique properties.
