M. Farrell Matt Farrell December 1, 2006 Lab 11: The Diels-Alder Reaction Purpose: The purpose of this experiment is to carry out the Diels-Alder reaction proficiently. By doing this, endo-norbornerne-5, 6-dicarboxylic will be synthesized from cyclopentadiene and make maleic anhydride. Then products will be tested for unsaturation. Background: The Diels-Alder reaction is an important synthetic tool for building cyclic systems. The reaction includes the cyclo addition of a conjugated diene and another unsaturated compound, dienophile. A dienophile simply comprises itself as a double or triple bonded conjugated with an electron withdrawing group(s). Acid catalysts are typically used to increase the rate of reaction. A typical Diels-Alder reaction includes: Page 1 of 4

M. Farrell The Diels-Alder reaction occurs by cycloaddition in which bonds are broken and formed in a continuous change from reactants to products. If groups in the dienophile are cis, they remain cis in the product. The Baeyer Test:
