3. 5. Anthracene and maleic anhydride with aluminum chloride give the adduct quantitatively in 1 1 2 minutes. Anthracene-maleic anhydride diels-alder adduct | C18H12O3 | CID 138503 - structure, chemical names, physical and chemical properties, classification, patents The purpose of this experiment is to form 9,10-dihydroanthracene-9,10-α,β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride, as shown in the reaction below. Anthracene acts as the diene and maleic anhydride functions as the dienophile. The Diels-Alder lab uses two reagents: anthracene and maleic anhydride to make the product: 9,10-Dihydro-9,10-ethanoanthracene-11,12-Dicarboxylic Anhydride 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 was the diene and maleic anhydride was the dienophile.

Be sure to wear gloves and avoid contact with these compounds. In a dry round-bottom flask, combine 1.0g of anthracene and 0.5 g of maleic anhydride, add 12 ml of xylenes (a mixture of dimethylbenzenes), and reflux the reaction mixture for about I'm wondering why maleic anhydride adds to the middle cycle of anthracene, and not the outer two. I would have expected that a Diels–Alder with the outer ring would be better, because I expected a naphtalene part to be lower in energy than two benzene parts (more resonance stabilisation). 2019-11-21 Other names: Anthracene, 2,5-furandione adduct; Anthracene,maleic anhydride adduct; endo-9,10-(α,β-Succinic anhydride)anthracene; 9,10(3',4')-Furanoanthracene-12,14-dione; 9,10-Dihydroanthraceno-9,10-endo-α,β-succinic anhydride; 9,10-Ethanoanthracene-11,12-dicarboxylic anhydride … Jump to content.

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

The reaction involves three bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Maleic anhydride and the product of the reaction are severe skin irritants. Be sure to wear gloves and avoid contact with these compounds. In a dry round-bottom flask, combine 1.0g of anthracene and 0.5 g of maleic anhydride, add 12 ml of xylenes (a mixture of dimethylbenzenes), and reflux the reaction mixture for about Maleic anhydride is a classic substrate for Diels-Alder reactions.

Diels Alder. a Diels-Alder reaction between maleic anhydride and anthracene was conducted. Reflux mechanism was used for the reaction to occur. 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%. It was not clear if a pure product had been formed because time
