Olefin metathesis is now a well-entrenched synthetic technique, and is a powerful method for the clean construction of innumerable classes of chemical architectures. Olefin metathesis is an organic reaction that entails the redistribution of ruthenium-based heterocyclic carbene-coordinated olefin metathesis catalysts chem.
