Electrocyclic Reaction

Electrocyclic Reaction Definition:

A pericyclic process in which a conjugated polyene undergoes cyclization.

Electrocyclic Reaction Explained:

A pericyclic rearrangement which is unimolecular, that become sigma bonded to one another that form shortened pi systems. In the process, one p bond is converted into a s bond, while the remaining p bonds all change their location. The newly formed s bond joins the ends of the original p system, thereby creating a ring.
