What is the purpose of the Grubbs reaction?
Olefin Metathesis Grubbs Reaction. Olefin Metathesis allows the exchange of substituents between different olefins - a transalkylidenation. This reaction was first used in petroleum reformation for the synthesis of higher olefins (Shell higher olefin process - SHOP), with nickel catalysts under high pressure and high temperatures.
Which is the best way to remove a metathesis catalyst?
Numerous methods have been reported for the removal of metathesis catalysts after a reaction. In general, you need a ligand or adsorbent that binds ruthenium better than your product, or a reagent that will react with the residual ruthenium preferentially.
How does olefin metathesis work in the Grubbs reaction?
Olefin Metathesis Grubbs Reaction. When molecules with terminal vinyl groups are used, the equilibrium can be driven by the ready removal of the product ethene from the reaction mixture. Ring opening metathesis can employ an excess of a second alkene (for example ethene), but can also be conducted as a homo- or co-polymerization reaction.
What do Grubbs and Schrock's catalysts consist of?
Grubbs’ and Schrock’s catalysts. A molecular brush is a grafted (co)polymer that consists of a linear main polymeric chain (backbone) and side polymeric chains ( Figure 3 ). The reader should not confuse polymeric brushes, which refer to linear polymers attached to surfaces, with molecular brushes.
