with the hydrogens highlighted on the ends of the diene and the dienophile, it may be easier to see the stereochmical relationships in the exo and endo products. In the exo product, the pair of hydrogens on the diene ends up cis to the pair of hydrogens on the dienophile when the rings become fused. In the endo product, the opposite is true: the pair of hydrogens on the diene come out trans to the pair of hydrogens on the dienophile when the rings fuse together.

the u detlined numbers are the official weights and the reaction is at the bottom of the page. i need the percent yeild of both products We were unable to transcribe this imageFUran is exceedingly volatile and flammable. Maleic anhydride is a strong irritant as are both products formed in this reaction. WEAR GLOVES. While wearing gloves wash your glassware and work area with acetone. Wash your hands thoroughly upon removing your gloves. Remember the product you are making is...

Hint-there should be three steps, with two arrows in each step the mechanism for the reaction of the alcohol and the anhydride, assuming it occurred after the 6 pts) if 4) Draw the most favorable conformation of the diene starting material. What implication does this have for the energy of the reaction? (2 pts) 5) Cyclopentene could be used in this reaction in place of...

laracteryze trie DreIS-AATder product. 3. The solvent used in this experiment is toluene. Draw one of the Diels- Alder products from the reaction of toluene with maleic anhydride. Why is this product not formed?
Which solvent (acetone or t-butyl alcohol) would be better to carry out the following reaction? Why? Draw the complete mechanism of this reaction using generic base B. CI
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).

Draw the endo and exo products for the reaction of 1,3(E)-pentadiene with maleic anhydride. Which is the major product?
Can someone draw the detailed reaction for the reaction of maleic anhydride and E,E-2,4-hexadien-1-ol. Also can you draw the stereochemistry and explain it using the endo rule.
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.
