Mechanism, references and reaction samples of the olefin metathesis. 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 has become a tool for synthetic organic and polymer chemists well-defined, functional group tolerant catalysts have allowed these advances. Why cross metathesis not used: •low catalyst activity to effect a reaction without an enthalipic driving force (ring strain) –newer catalysts have been developed. Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double.
