The mechanism for transition metal-catalyzed olefin metathesis has been widely researched over the past forty years rcm undergoes a similar mechanistic pathway as other olefin metathesis reactions, such as cross metathesis (cm), ring-opening metathesis polymerization (romp), and acyclic diene metathesis (admet.

Chauvin incubated the earliest imaginary mechanism involving a [2+2] cycloaddition reaction between the transition metal alkylidene complex and the olefin substrate to form a four membered ring metallacyclobutane intermediate.

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.

General mechanism: chauvin incubated the earliest imaginary mechanism involving a [2+2] cycloaddition reaction between the transition metal alkylidene complex and the olefin substrate to form a four membered ring metallacyclobutane intermediate. The mechanism of this reaction is identical to that of the olefin metathesis reaction except that the final step is not reversible.

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 for their elucidation of the reaction mechanism and their. Ring-closing metathesis is a variant of the olefin metathesis reaction in which alkylidene moieties are exchanged to form a ring the most common catalysts for this reaction are complexes of molybdenum or ruthenium.

Olefin metathesis is a fundamental chemical reaction involving the rearrangement of carbon–carbon double bonds and can be used to couple, cleave, ring-close, ring-open, or polymerize olefinic molecules.
