Ruthenium Olefin Metathesis Catalysts Bearing an <i>N</i>-Fluorophenyl-<i>N</i>-Mesityl-Substituted Unsymmetrical <i>N</i>-Heterocyclic Carbene

Abstract

Two new ruthenium-based olefin metathesis catalysts, each bearing an unsymmetrical N-heterocyclic carbene ligand, have been synthesized and fully characterized. Their catalytic performance has been evaluated in ring-closing metathesis, cross metathesis, and ring-opening metathesis polymerization reactions.
