Examples

  • And then we probably won't get today to catalytic hydrogenation and to polymerization and metathesis where metals are involved.

  • In a metathesis reaction, the compounds A and B trade elements with C and D to create new compounds.

  • So if you bring in this alkylidene compound and do the trick of metathesis, you get that.

  • A ring-opening metathesis polymerization injected similar to reaction injection molding, where too-quick crosslinking is a problem.

Morphology

metathesis = thesis (opaque) = meta + thesis

The chemistry sense is a specialized extension of the same classical formation, but the relationship is not transparent to an average learner.

Etymology

Metathesis comes from the Greek parts meta- 'change' and -thesis 'placing', so it means 'changing places'. In chemistry it names a reaction where parts of two compounds 'swap partners' to form two new compounds.
