What is the side reaction of CIS norbornene 5, 6, 6-endo?
Mechan Cyclopentadiene Maleic Anhydride cis-Norbornene-5,6-endo-dicaroboxylic anhydride Diene DienophileDiels-Alder Product Side Reaction The side reaction which occurs during the production of cis-Norbornene-5,6-endo-dicaroboxylic anhydride is the dimerization of the diene.
What is the melting point of CIS norbornene 5, 6 dicarboxylic anhydride?
The literature value for the melting point of cis-Norbornene-5, 6-endo-dicarboxylic anhydride is 165º C. The experimental value we obtained through the Diels- Alder reaction was 160- 163º C. We were only able to produce a yield of 20.2%.
How is cis-norbornene 5, 6, 6-cyclopentadiene prepared for the Diels-Alder reaction?
Cis-Norbornene-5,6-endo-dicarboxylic anhydride Cyclopentadiene was previously prepared through the cracking of dicyclopentadiene and kept under cold conditions. In a 25 mL Erlenmeyer flask, maleic anhydride (1.02 g, 10.4 mmol) and ethyl acetate (4.0 mL) were combined, swirled, and slightly heated until completely dissolved.
Why is cyclopentadiene the limiting reagent for CIS-norbornene?
Through these calculations we can see that the cyclopentadiene is the limiting reagent is the cyclopentadiene because the reaction between cyclopentadiene and maleic anhydride is a 1:1 reaction. Thus, the maximum amount of moles of cis-Norbornene-5, 6-endo-dicarboxylic anhydride we can produce is:

For this experiment, our dicyclopentadiene is the diene and the maleic acid is our dienophile.
Thus, the maximum amount of moles of cis-norbornene-5, 6-endo-dicarboxylic anhydride we can produce is: now that the theoretical yield has been calculated, we can compare the experimental yield with the theoretical yield: discussion: the lit value for the melting point of cis-norbornene-5, 6-endo-dicarboxylic anhydride is 165º hundred.
