Question

Predict the product of the following pericyclic reaction. Is this [5,5] shift a suprafacial or an antarafacial process?

Short answer

The product of the following pericyclic reaction can be predicted.

Step-by-step solution

Statement for pericyclic reaction

The pericyclic reaction can be given as a thermal [5,5] sigmatropic rearrangement reaction. There is an involvement of five electron pairs in the reaction. It takes place through the suprafacial pathway.

Product of the pericyclic reaction

The pericyclic reaction’s product can be shown as,

It is a suprafacial process for thermal [5,5] sigmatropic rearrangement.
