1 Jul 2017 Reaction mechanism for the reaction of anthracene and maleic anhydride.

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

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. Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%. Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 37.42% for the recrystallized product was collected.

Anthracene and maleic anhydride

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. anthracene 9, 10-dihydroanthracene- 9,10-oçß-succinic anhydride* maleic anhydride potassium bromide xylene *product 1998 Chemical Education Resources 10-mL graduated cylinder hot plate 2 melting point capillary tubes microspatula 25-mL round-bottom flask support stand 13 x 100-mm test tube 2 utility clamps 3-mL product vial watch glass Diels Alder Rxn - SEE TITLE SEE TITLE .
