Schrock and Grubbs ; Air sensitive ; Initially were molybdenum and ruthenium based, respectively ; Both won Nobel Prize in Chemistry for work in olefin metathesis, along with Chauvin; Images from Pappenfus, T. M. Synthesis and Catalytic Activity of Ruthenium-Indenylidene Complexes for Olefin Metathesis, J.

Chem. Ed. Ru K-edge XAS data indicate that second generation ruthenium-based olefin metathesis precatalysts (L = N-heterocyclic carbene) possess a more electron-deficient metal center than in the corresponding first generation species (L = tricyclohexylphosphine).

This surprising effect is also observed from DFT calculations and provides a simple rationale for the slow phosphine dissociation kinetics. Among many catalysts that are eligible for the host-guest removal, Ru olefin metathesis catalyst was studied due to high practical utilities and high stability against air and moisture.

The olefin metathesis reaction is an important tool in synthetic chemistry to form a carbon-carbon double bond in the presence of a transition metal catalyst Apr 22,  · The main advantage of latent olefin metathesis catalysts is that it can be mixed with the monomers without concomitant polymerization, which allows for longer handling of the catalyst/monomer mixtures or even storage for longer periods (S.
