The Grubbs Metathesis Reaction

The Grubbs reaction exchanges the groups attached to the double bond of alkenes. The two alkenes exchange partners to give two new products in which neither one is oxidi2ed or reduced. This process is a metathesis reaction. [Pg.584]

Most of the time both reactants for the Grubbs reaction are terminal alkenes. When two terminal alkenes react, they exchange methylene groups. Thus, one of the products is ethene, which escapes from the solution as a gas, converting a reversible process to one that is effectively irreversible. [Pg.584]

For example, the reaction of 1-butene with 1-propene gives (E)-2-heptene and ethene. [Pg.584]
