What is a Diels Alder reaction between anthracene and maleic anhydride?
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.
Is anthracene a classic diene?
Being an easily available conjugated π-electron-rich carbocyclic system, anthracene ( 1a) has been widely exploited as a classic diene in Diels–Alder reactions wherein its chemical reactivity and transformational effectiveness are subsidized by the partial loss of aromaticity.
What are the thermodynamic properties of anthracene + maleic anhydride adduct?
The other thermodynamic properties of the (anthracene + maleic anhydride) adduct derived from those measured properties are: Δ fHmo (C 18 H 12 O 3, cr, 298.15 K) = − (418.2±6.4) kJ·mol −1 and Δ fHmo (C 18 H 12 O 3, 1, 298.15 K) = − (389.7 ± 7.7) kJ·mol −1.
