A Neat Diels-Alder Reaction: 910-dihydroanthracene-910

The Diels-Alder reaction is a concerted [4+2] cycloaddition between a diene and a dienophile (which is often an alkene) The reaction simultaneously forms two C-C single bonds The reaction you will carry out is between anthracene (the diene) and maleic anhydride (the dienophile): O + heat

How do you mix 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 30 min. Use an IR lamp as the heat source. Allow the mixture to cool to room temperature.
Why do we need NMR spectroscopy for anthracene synthesis?
Because many of these applications involve the incorporation of anthracene into a much larger macromolecule mainly through a Diels Alder reaction, monitoring such transformations using NMR techniques requires an accurate appreciation of the chemical shifts of protons and carbons in these materials.

How are 9 substituted anthracene derivatives obtained?
9-substituted derivative (2) were obtained by reacting the corre- sponding anthracene derivative with 1-octylmaleimide as de- scribed in Scheme 1. The two other compounds (3 and 4) are Diels –Alder adducts of 9- substituted anthracene, obtained by reacting the corresponding anthracene derivative with maleic anhydride (Scheme 2).
