Draw and discuss the mechanism (with arrows to show electron movements) of the Diels-Alder reaction between anthracene and maleic anhydride. Draw the orientation and phases of the reacting p-orbitals showing how they overlap in a “suprafacial” geometry to form the product
Draw and discuss the mechanism (with arrows to show electron movements) of the Diels-Alder reaction between...
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.
tion 5 continued) c. Anthracene is known to act as the diene in Diels-Alder read as maleic anhydride as shown below. Draw the str reaction and draw a reasonable mechanism illustrating its comma explanation for the observed regioselectivity. he diene in Diels-Alder reactions with dienophiles such s shown below. Draw the structure of the major product of this nechanism illustrating its formation. Give a brief [4 marks) Propose a detailed mechanism for the following two transformations. Use curved arrows to...
a. Draw a curved arrow mechanism for the formation of the diels alder product you obtained by combining alpha-phellandrene and maleic anhydride. b. How many possible diels alder products could be formed in this reaction (draw them and state how they are related to each other)? c. Which one is formed as the major product in the reaction and why?
Calculate the theoretical yield of the Diels-Alder reaction between anthracene (100 mg) and maleic anhydride (55 mg). Which is the limiting reagent ? Show all calculation steps.
draw curved arrows Draw curved arrows to complete the Diels-Alder mechanism for the two reactants shown. Then draw the product of the reaction in the box to the right. Do not show stereochemistry.
Write a reaction scheme and structures for the diels-alder reaction to 0.8 g of anthracene and 0.40g of maleic anhydride and add 10 mL of p-xylene
Draw the complete reaction mechanism for the below. (R groups are not acceptable, please draw the complete structure for every step.) Diels Alder reaction between one mole of anthracene (molecular weight = 178.23g/mol) and one mole maleic anhydride (molecular weight = 98.06g/mol) forms one mole of 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (molecular weight = 276.29g/mol).

(Diels-Alder reaction of anthracene with malice anhydride) Calculate the percent yield of your product before and after recrystallization. Compare the percent yields and explain why they are not the same. 100 mg anthracene 55 mg maleic anhydride product before recrystallization: 0.083 g product after recrystallization: 0.038 g
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.
