Mark DeWitt 35651743 Chemistry 216 Section 128 Experiment 9: The Diels-Alder Reaction Introduction The purpose of this experiment was to perform the Diels-Alder reaction. This was completed by reacting a conjugated diene (cyclopentadiene) and a dienophile (maleic anhydride) in order to form a six-membered ring called cis-norbornene-5,6-endo- dicarboxylic acid anhydride. The final product and its purity were confirmed through TLC, IR, and melting point analyses. Reaction Results These are the steps that I performed for the experiment: 1. Dissolved 0.20 g of powdered maleic anhydride in 1 mL of ethyl acetate in a tared 10x100 mm reaction tube. 2. Added 1 mL of hexane. 3. Added 0.20 mL (0.160 g) of cyclopentadiene. 4. Mixed and observed reaction.
