Radin Bonakdar Lab Performed: 1/26/17 Organic Chemistry 2204/22 Lab Report Due: 2/2/17 TA: Dr. Hill Experiment 15: The Diels-Alder Reaction: 9,10-Dihydroanthracene-9,10-α, β-succinic Acid Anhydride Objective: The purpose of this experiment is to investigate the Diels-Alder reation and be able to explore the rule of an aromatic ring as the diene substrate (anthracene) with activated dienophile (maleic anhydride). In addition, learning the use of drying tube for the first time. Experimental Procedure: The procedure was followed as described in Mayo, pages 271-272, with the modifications listed in the Blackboard document. Reaction Scheme:
