What Role Do Metal Carbene Complexes Play in Catalysis?
Metal carbene complexes are pivotal in numerous catalytic transformations. One of the most significant applications is in olefin metathesis, where these complexes facilitate the exchange of alkylidene groups between alkenes, leading to the formation of new carbon-carbon double bonds. This process is crucial in organic synthesis and polymer chemistry.
Another important application is in cyclopropanation reactions, where metal carbene complexes help in the formation of three-membered carbocycles. This reaction is valuable for the synthesis of various natural products and pharmaceuticals.
