THE DIELS-ALDER REACTION
Synthesis of endo-Norbornene-5, 6-cis-dicarboxylic Anhydride and Endo-Nobornene-5, 6-cis-dicarboxylic acid
The purpose of this experiment was to perform the Diels-Alder reaction which is one of the most powerful reactions in organic chemistry. The Diels-Alder reaction is a cycloaddition reaction between a diene and a dienophile to produce a six-membered-ring. In part A, maleic anhydride and cyclopentadiene were used as the dienophile and the diene, respectively. Part A reaction synthesized endo-norbornene-5, 6-cis-dicarboxylic Anhydride which then used as a reactant of the part B reaction. Part B reaction was the hydrolysis of the anhydride in boiling water to form endo-Nobornene-5, 6-cis-dicarboxylic acid.
