INTRODUCTION In this lab we will synthesize the compound cyclohexa-1,4-diene-1,2-dicarboxylic acid dimethyl ester, using the classic Diels-Alder (4+2) cycloaddition reaction, starting with 1,3-butadiene as the diene, and butynedioic acid dimethyl ester as the dienophile. Once synthesized, you will characterize the substituted cycloalkene product by infrared (IR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy to confirm that you actually synthesized what you set out to create. BACKGROUND German chemists Otto Diels and Kurt Alder first described the organic reaction that now bears their names in 1928, and earned them the Nobel Prize in Chemistry in 1950. In this reaction, a conjugated diene will react with a dienophile, if an appropriate electron-withdrawing group is attached to the dienophile, to produce an adduct containing two new o bonds. This is important, because the synthesis of new C-C bonds is relatively difficult, and because the products of Diels-Alder reactions containing cyclohexene rings can be used in other reactions form complex molecular structures. er of curloaddition reactions ed due date.
