Question

what happens when furan reacts with maleic anhydride​

Answer 1

Answer:

It is a concerted cyclization reaction which generates an adduct of the starting diene (furan) and dienophile (maleic anhydride) that contains two new C−C bonds. The decomposition of this compound at its melting point of approximately 114∘C simply gives you the original reactants back in a retro Diels-Alder.
