Diels Alder Reaction of Tetraphenylcyclopentadienone Purpose of the Experiment: To successfully synthesize dimethyltetraphenylphthalate via a Diels Alder reaction. The melting point of the product is 258oC. Why should we not do a melting point of the product? The intermediate in brackets loses CO to form the product at 180oC. If the C=O were replaced by CH2, do you think the same type of reaction would happen with loss of :CH2?

Following is an example of a type of reaction known as a Diels-Alder reaction 1,3-Pentadiene Ethylene 3-Methylcyclohexene (a racemic mixture) The Diels-Alder reaction between a diene and an alkene is quite remarkable in that it is one of the few ways that chemists have to form two new carbon-carbon bonds in a single reaction. Given what you know about the relative strengths of carbon-carbon sigma and pi bonds, would you predict the Diels-Alder reaction to be exothermic or endothermic? Explain your reasoning.

The following is an example of a hetero Diels-Alder reaction, because a noncarbon atom (in this case, an N atom) is involved in bond formation and bond breaking. Draw the curved arrows necessary to account for this transformation. OCH3 OCH3 + N- Hydroquinone, benzene, 25 °C, 90 min 86%
How do you account for the fact that the dipole moments of fluoromethane and chloromethane are almost identical even though fluorine is considerably more electronegative than chlorine?
Step 6: Now that you have determined the substrates and mechanism of a Diels-Alder reaction, you will learn how to recognize when you should use the Diels-Alder reaction. In a synthesis reaction, if you are given a cyclohexene product with no other obvious functional group transformations and an electron-withdrawing group two carbons away from the alkene, it is likely made via the Diels-Alder reaction. Deduce the structures of the starting materials to form the Diels-Alder adduct shown. ..... CN CN Diene + Dienophile
