Heterobimetallic Pd‐Ru Catalysts for the Synthesis of Functionalized Polynorbornenes via Reductive Heck/ROMP Reactions

open access: yesApplied Organometallic Chemistry, Volume 39, Issue 11, November 2025.
Monometallic and heterobimetallic Ru‐PdL complexes were synthesized and fully characterized. Their electrochemical properties were investigated by cyclic voltammetry. The Ru‐PdL complexes catalyzed the hydroarylation of NBD and the ROMP of Ph‐NBE. One complex catalyzed both reactions via tandem catalysis in one pot, converting NBD to poly (Ph‐NBE ...
