Why does the diene shown below fail to undergo a Diels-Alder reaction with even the most reactive dienophiles?

Diels-Alder Reaction

A chemical reaction between a conjugated diene and a substituted alkene, typically producing a cyclic compound.

Dienophiles

Chemical species that participate in Diels-Alder reactions by combining with dienes to form cyclic compounds.

Recognize and explain the impact of molecular structure on reactivity and reaction mechanisms.

Verified Answer
