Diels Alder reaction is a chemical reaction between a conjugated
diene and a substituted alkene, commonly called dienophile to form
a substituted cyclohexane derivative. It is one of the example of a
pericyclic reaction with a concerted mechanism. The reaction is
stereospecific.

This is my crude product H NMR. (Exp: Diels-Alder Reaction in
water)
Anthracene-9-methanol and N-methylmaleimide react in water, and
refulx 1.5h, than Anthracene-N-methylmaleimide Des-Alder adduct was
created.
TA told me that specturm is excellent, but there are so many
mistakes at labels. Please see my data, and let me know if there
are mistakes.

Anthracene -9-methanol and 3 equivalents of N-methylmaleimide were mixed with water in an Erlenmeyer flask and heated to reflux( Diels-Adler reaction) TLC was prepared using a 1:1 ratio ethyl acetate: hexane. We got Rf=0.8 for N-methylmaleimide Rf=0.6 for anthracene and Rf=0.3 for the mixture. What information does this provide?
What is the product of a diels-alder reaction between
9-anthracenemethan and N-methylmaleimide in water? what is the
product's name?
Figure 1. The reaction between 9-anthracenemethanol and N-methylmaleimide N-CH3 Н.о -CHs Он он Experimental Instructions N-methylmaleimide is corrosive and should be handled with care. Always wear gloves and eye protection in the laboratory 1. Place 0.065q of finely pulverized 9-anthracenemethanol and 50 mL of water in a 100-mL round-bottomed flask equipped with a magnetic.stir bar. 2. Add 3 molar equivalents of...
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
(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
Calculate the theoretical yield and percent yield of the Diels-Alder product Amount of 9-anthracenemethanol used: 0.065 g Amount of N-methylmaleimide used: 0.104 g Diels-Alder product recovered: 0.293 g Molar mass of 9-anthracenemethanol: 208.26 g/mol N-methylmaleimide: 111.11 g/mol
5. Arrange the following solvents in increasing order of reaction rate for Diels-Alder reaction between anthracene and 1,3-dimethylcyclopentene. Draw structure of product with appropriate stereochemistry. 10 points Ethyl acetate diisopropyl ether Ethanol Water Hexane The same order of reactivity would not necessarily result in the highest yield of the product - meaning, the solvent with highest reactivity would not necessarily give you the most amount of product based on procedure employed in the lab. Explain why this is so.
