Synthesis, Isolation, and Characterization of Diels–Alder Adducts between 1,4-Dialkoxyanthracenes and Maleic Anhydride. Bulletin of the Chemical Society of Japan 2004 , 77 (7) , 1385-1393.

Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly. 000. z oo Anthracene Maleic anlydride 9,10-dihydroanthracene- -9,10-a.B-succinic anhydride Objectives: In this experiment, you will • Synthesize 9,10-dihydroanthracene-9,10-c-B-succinic anhydride.

Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 37.42% for the recrystallized product was collected. Hand-drawn Arrow Pushing Mechanism of anthracene and maleic anhydride to 9,10-dihydroanthracene-9,10-GB-succinic acid anhydride (4 pts.): NMR Assignments (4 pts, total) Draw the structure of 9.10-dihydroanthracene-9,10-B-succinic acid anhydride (label the protons with lowercase letters from the NMR spectrum found in the Online Experiment Video section) (4 pts.) Theoretical Yield of 4-cyclohexene-cis-1,2-dicarboxylic anhydride = moles of limiting reactant (maleic anhydride) x molar weight of 4-cyclohexene-cis-1,2-dicarboxylic anhydride. Actually used 2.79 grams of 3-sulfolene and 1.63 grams maleic anhydride. 2.79 grams C4H6O2S x = 0.0236 mol C4H6O2S = 0.0236 mol C4H6.

Maleic anhydride is a classic substrate for Diels-Alder reactions. It was used for work in 1928, on the reaction between maleic anhydride and 1,3-butadiene, for which Otto Paul Hermann Diels and Kurt Alder were awarded the Nobel Prize in 1950. It is through this reaction that maleic anhydride converted to many pesticides and pharmaceuticals.

The solution turned a yellow color when the reactants were added together. The reflux was then started, and once it began to boil, it was boiled for 30 minutes.

First you need to find the molar mass:-look up on the periodic table what is called the atomic weight or molar mass (should be under the symbol). This is the number of grams in one mole of this element.
