Diels alder bicyclic ring
WebThe purpose of this experiment is to combine anthracene and maleic anhydride though a Diels-Alder reaction to form the product 9,10-dihydroanthracene-9,10-a, b-succinic anhydride. In a Diels-Alder reaction, two open-chain starting materials (called a diene and a dienophile) react though a cycloaddition reaction and from a six-membered ring.
