First, the 140 °C boiling point provides a good reaction temperature. 1-octylmaleimide or maleic anhydride as a dienophile, assisted by their crystal structures could serve as a reference for such an endeavor. An octylmaleimide Diels–Alder adducts of anthracene (1) and a 9-substituted derivative (2) were obtained by reacting the corre-sponding anthracene derivative with 1-octylmaleimide as de-scribed in Scheme 1.

Weigh out 0.80g of anthracene and 0.40g of maleic anhydride (both are solids). Add the two solids into the flask. (Be sure the flask has cooled for at least two minutes before adding the solids, or they will melt.) Carry the round-bottomed flask to the hood Norbornene-5,6-endo -dicarboxylic anhydride from the reaction of the conjugated diene Cyclopentadiene with the dienophile Maleic anhydride (see Figure 2).

Anthracene acts as the diene and maleic anhydride functions as the dienophile. Diels-Alder Reaction of Anthracene and Maleic Anhydride Carly Stewart, Organic Chemistry 2, 1, 1 July 2029 Department of Biology and Chemistry, Liberty University ■ INTRODUCTION A Diels-Alder reaction is a chemical reaction between a substituted alkene (dienophile) and a conjugated diene to form a substituted cyclohexene. 1 This is a vital reaction within chemistry due to its ability to form a 6 membered ring and the ability to control stereo and regiochemistry within the reaction.

To increase the speed of the reaction, xylene was used because of its high boiling point.After the reaction was complete, 1.08g of the off white product was obtained with a yield of 69.7%.

Assume you start with 1.012 gram anthracene and 0.505 grams maleic anhydride: what is the theoretical yield of the product? 1.012 grams Anthracene 1 mole anthracene 1 mole product 276.29 grams 1.56879 178.23 grams 1mole anthracene 1 mole product LIMITING REAGENT 0.505 grams maleic anh. 1 mole maleic anh. 1 mole product 276.29 grams 1.422868 molar mass of anthracene, 178.23, gives the moles of anthracene used, 0.00160. The mass of the maleic anhydride used was 0.152 g and the molar mass is 98.06, giving 0.00155 moles of mal eic anhydride to use in this reaction, and making maleic anhydride the limi ting reactant.
