Draw the products of these 4 dienes with maleic anhydride. Provide the melting point of the adduct as well. Thank you.
Diels-Alder reaction is a [4+2] cycloaddition reaction of a conjugated diene and an alkene (dienophile). It is a stereospecific reaction giving rise to syn addition products. When different regio or stereoisomers are possible, the product which is sterically most favoured in transition state and/or in final product, is predominantly formed.
Diels-Alder addition of alpha-terpinene and maleic anhydride gives endo product. endo product is favoured due to pi-interactions between diene and C=O group of maleic anhydride.
Similarly, Diels-Alder addition of alpha-phellandrene and maleic anhydride gives endo product.
The products are shown in the image uploaded.

EXPERIMENT 2A DIELS-ALDER REACTION OF ANTHRACENE REFERENCES Pavia et al (4/e): Tech. 6.1/6.2, 7.2-7.4 Klein (1/e) pp. 784-792 EQUATION heat Diels-Alder Adduct 9,30-dihydroanthracene-9,10- endo-o B-seccinic anhydride mp 262264 PROCEDURE Place 0.200 grams of anthracene and an equal molar amount of maleic anhydride in 5 mL of xylenes in a 10-mL round-bottom flask with a magnetic stir bar. Attach a water-cooled condenser and reflux for 60 minutes. Allow the solution to cool to room temperature and then place the flask in...
What is the objective of this experiment? The reaction solvent for this experiment is xylene. What property of this solvent makes it a better choice than toluene or benzene? Draw the orbitals involved in the 4+2 electrocyclization for this reaction. Draw the structures of the reactants as best you can. It may be appropriate to abbreviate the structure of anthracene. IR is not provided for this reaction product. Why is IR not useful for monitoring the reaction or characterizing the...
As you know from Project 4, McCormick & Company is considering building a new factory in Largo, Maryland. McCormick & Company decided to offer $4,424,000 to obtain the land for this project. The new factory will require an initial investment of $350 million to build the new plant and purchase equipment. You have been asked to continue your work from project 4 with a full analysis of the proposed factory, including the start-up costs, the projected net cash flows from...
