alkene olefin metathesis

Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative organic reactions.
Synthetically useful, high-yield procedures for lab use include ring closure between terminal vinyl groups, cross metathesis - the intermolecular reaction of terminal vinyl groups - and ring opening of strained alkenes. When molecules with terminal vinyl groups are used, the equilibrium can be driven by the ready removal of
Metathesis in acid-base chemistry and ion exchange is well defined and simple. However, until recently, bond formation in organic reactants is difficult without the presence of catalysts. • In the past 30 years or so industry has used olefin metathesis to form alkenes into other alkenes through a variety of mechanisms.
