Question

Show the product of the Diels–Alder dimerization of cyclobutadiene.

Short answer

It is a reaction in which a cyclohexene derivative is formed by the reaction of dienophile (substituted alkene) and a conjugated diene. This involves the shift of four pi electrons of diene and two pi electrons of dienophile.

Step-by-step solution

Diels-Alder reaction

It is a reaction in which a cyclohexene derivative is formed by the reaction of dienophile (substituted alkene) and a conjugated diene. This involves the shift of four pi electrons of diene and two pi electrons of dienophile.

Product of dimerization

Two molecules of cyclobutadiene react to form the Diels-Alder product.
