(organic chemistry) A class of organic reaction in which fragments of alkenes are redistributed

Exchange of atoms between compounds.

(prosody) A form of metathesis or transposition involving quantity or vowel length, by which two neighboring vowels – one long, one short – switch their lengths, so that the long one becomes short, and the short one becomes long.

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species which results in the creation of products with similar or identical bonding affiliations..

In polymer chemistry, ring-opening metathesis polymerization is a type of chain-growth polymerization involving olefin metathesis.

a widely used variation of olefin metathesis in organic chemistry for the synthesis of various unsaturated rings via the intramolecular metathesis of two terminal alkenes, which forms the cycloalkene as the E- or Z- isomers and volatile ethylene.
