Olefin Metathesis Grubbs Reaction Olefin Metathesis allows the exchange of substituents between different olefins - a transalkylidenation This reaction was first. Abstract A series of ruthenium-based olefin metathesis catalysts coordinated with unsymmetrical N-heterocyclic carbene (NHC) ligands has been. Olefin metathesis is a chemical reaction in which two carbon-carbon double bonds (olefins) come together and exchange with one another, forming new olefinic products. P Wipf Chem 1410 Page 1 1 Synthesis of Ruthenium Olefin Metathesis Catalysts Introduction Well-defined metal alkylidene complexes are: Mo. It has been noted commonly, the highly efficient metathesis catalysts are being widely used by pharma and chemical industries for the production of high value chemicals.

Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double.
