Olefin metathesis is a popular and useful reaction. In the presence of certain transition-metal compounds, including various metal carbenes, olefins exchange the. The bonding-partner switcheroo that happens in metathesis reactions has been a boon for molecule makers. Chemists who made crucial discoveries in olefin metathesis. Olefin metathesis is a popular and useful reaction. In the presence of certain transition-metal compounds, including various metal carbenes, olefins exchange the. What is Olefin Metathesis? In chemical reactions, the bonds between different atoms are broken and new bonds are formed. This typically requires the use of a catalyst.

Grubbs' catalysts are a series of transition metal carbene complexes used as catalysts for olefin metathesis. They are named after Robert H. Grubbs, the chemist who. Olefin Metathesis: Catalysts and Catalysis Matthew Cohan and Dr. Marcetta Darensbourg. The first well-defined ruthenium catalyst for olefin metathesis was discovered in 1992. It was prepared from RuCl 2. The first-generation Grubbs catalyst. Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double.
