The reaction studied in this experiment is an example of a 1, 4 addition by an activated alkene dienophile across the 9, 10 positions of anthracene. This lab experiment was successful because we were able to identify that the anthracene was the diene and maleic anhydride was the dienophile.
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.
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. This was low due to the fact…show more content… Students Calculated an Rf value of 0.93 for Anthracene, an Rf value of 0.63 for Maleic Anhydride, and an Rf value of 0.78 for the crude product. These results show that Anthracene was the least polar solvent and Maleic Anhydride was the most polar.
3) maleic anhydride (dienophile) anthracene adduct) (diene) The reaction is carried out in xylene, which is actually a mixture of the three dimethylbenzenes, for three reasons.
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. The Diels-Alder Reaction of Anthracene with Maleic Anhydride - Lu Le Laboratory Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest The Diels-Alder reaction is a cycloaddition reaction, a reaction in which two molecules undergo addition to yield a cyclic product.
3) maleic anhydride (dienophile) anthracene adduct) (diene) The reaction is carried out in xylene, which is actually a mixture of the three dimethylbenzenes, for three reasons. First, the 140 °C boiling point provides a good reaction temperature.
maleic anhydride should produce 2.27g of 4-cyclohexene-cis-dicarboxylic anhydride and 2.54g of 4-cyclohexene-cis-1,2-dicarboxylic acid (Eqs.1 and 2). The mass of the dicarboxylic anhydride before drying was 1.90g.
