) xylene140 coooooo figure 2: mechanism of the diels-alder reaction conclusions write a brief paragraph that summarizes your results the diels-alder adduct, 9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylic anhydride, was successfully synthesized from anthracene and maleic anhydride. Diels alder lab report diels alder lab report 2 february 2017 chemistry be sure to address any questions posed in the lab procedure as well as any additional questions that your ta wants you to answer you should also analyze any nmr spectra that you have from the reaction (if applicable) this particular diels-alder reaction exploits.
The diels-alder reaction is a concerted mechanism 4 the cited melting point falls within the range of experimental melting point range the product retains also the s-cis conformation which means that the purity of the adduct is quite high and that reflux was successful in inducing the dielsalder reaction between sulfolene and maleic. The simplest diels-alder reaction is between 1,3-butadiene and ethylene: the formation of new carbon-carbon bonds is one of the most important aspects of synthetic organic chemistry when a synthetic sequence calls for the formation of a ring of carbon atoms, this problem is compounded.

156 synt 717: the diels-alder reaction of anthracene with maleic anhydride (diene (diene (eq1) adduct (eq 2) adduct reactants and the symmetry of their molecular orbitals control the. Diels-alder reaction is reversible by “cracking” dicyclopentadiene using slow distillation and keeping the cyclopentadiene cold at the boiling point of dicyclopentadiene, equilibration with the minor lab report – include the following: all “minor” components described in the “how to write a strong lab report” general guidelines.
Diels-alder reactions are a highly efficient way to synthesize cyclohexene rings in this experiment a diels-alder reaction was carried out between 1,3-cyclohexadiene and maleic anhydride to form a new bicyclic ring adduct, biclycloocta-5-ene 2,3. Experiment 2 (organic chemistry ii) pahlavan/cherif diels-alder reaction preparation of endo-norbornene-5, 6-cis-carboxylic anhydride purpose a) study conjugated dienes b) study diene and dienophile a fractional distillation setup as used previously in lab, or as described above this apparatus will use a 100-ml.
The melting point analysis shows that the product of the diels-alder reaction was somewhat impure, but the product of the hydrolysis of the diels-alder adduct was very pure the yield of the reactions was also high 89% and 75% for the two processes respectively.
