a) a-phellandrene combined with Maleic Anhydride (diels-alder) followed by NaOH produces one product. Treating with NaOCH3, followed by an acidic workup produces a new product. What is it's structure and why is not a good derivative to use to characterize the Diels-Alder product? b) Toluene in used as a solvent in these Diels-Alder reactions. Draw the Aiels-alder products from the reaction of toluene and maleic anhydride. Why is this product not formed during traditional Diels-Alder reactions?

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.

Complete the mechanism of the following Diels-Alder reaction by drawing the curved arrows for the concerted reaction and the final product formed. (Note that the COOH group is a carboxylic acid group, which is electron withdrawing.) Interactive 3D display mode Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds, including charges where needed. Indicate the mechanism by drawing the electron-flow arrows on the molecules. Arrows should start on...

There are three possible products for the Diels-Alder reaction, each involve the addition of one molecule of maleic anhydride to one molecule of anthracene. Draw each possible product, clearly showing the stereochemistry of the reaction.

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.
