Acyclic diene metathesis



Acyclic diene metathesis or ADMET is a special type of olefin metathesis used to polymerize certain terminal dienes to polyenes:

The new double bonds formed can be in cis- or trans-configuation.

It is a type of step growth condensation reaction whereas the other metathesis reaction, ring-opening metathesis polymerization is a chain-growth polymerization.


ADMET was introduced by K. B. Wagener in 1991 [1]. He successfully polymerized 1,5-hexadiene to polybutadiene with 70% trans double bonds and Weight average molar mass of 28000.

ADMET has been applied in the synthesis of new supramolecular structures [2].
