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. Anthracene was the diene and maleic anhydride was the dienophile.

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 molar enthalpy of fusion of this adduct at its melting temperature (534.07 K), as measured by a 910 DuPont d.s.c. and a 9900 DuPont thermal (analyzer + digital computer), was found to be (36.3 For the TLC plate, students calculated retention factors for Anthracene, Maleic Anhydride, and the crude product Anthracene-maleic anhydride diels-alder adduct.The Rf value for Anthracene was 0.93, Rf value for Maleic Anhydride was 0.63 , and the Rf value for the crude product was 0.78.
In the present experimental work, the energy of combustion of the crystalline Diels-Alder adduct of anthracene and maleic anhydride: C 18 H 12 O 3, was measured with a model 1241 Parr automatic calorimeter and a Parr model 1710 calorimeter controller.The standard molar enthalpy of combustion of the (anthracene + maleic anhydride) adduct at p o = 0.1 MPa was â ¦ In this lab, the 4 electrons
I looked up the molecular formula of this and it is C4H2O3. a. 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. -C: 12.01 g 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).
