Predict the product of the Diels-Alder reaction of this compound with cyclopentadiene. Draw your product in the window below.
Cyclopentadiene is a better diene for a Diels-Alder reaction that a non-cyclic diene like 1,3-pentadiene. However, this increased reactivity also causes cyclopentadiene to dimerize much more easily. Explain the why cyclopentadiene is more reactive than 1,3-pentadiene.

For the following Diels-Alder reaction between cyclopentadiene and methyl methacrylate: LABEL the observed products as either exo or endo and CIRCLE the major product (3 pts) Me CO2Me CO2Me heat CO2Me
diels alder reaction Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in this experiment? The infrared spectrum of the adduct is given in this experiment. Interpret the principal peaks.
The Diels-Alder reaction you will conduct in this experiment is between cyclopentadiene and maleic anhydride (the anhydride of cis-2-butendioic acid): diene dienophile The glassware is predried and a drying tube is used to prevent the hydrolysis of maleic anhydride to maleic acid (cis-2-butendioic acid): On heating, maleic acid isomerizes to fumaric acid (trans-2-butendioic acid). Show the mixture of products that would be formed if a small amount of moisture was present in the Diels-Alder reaction you have performed.
