1. This diene reacts rapidly with electrophilic alkenes, such as maleic anhydride. 2. The HOMO of the dienophile reacts with the LUMO of the diene . 3. To effect a Diels-Alder reaction only a conjugated diene will suffice. 4. It is prepared from potassium tetrachloroplatinate and the diene : 5. The diene is known to react with amines, aldehydes, alkenes and alkynes. 6. Next, the allyl alcohol is oxidized to the diene ( Step C ). 7. The catalyst encapsulates the diene and dienophile, increasing the effective concentration of reactants. 8. Drew said Diene did not enroll for the fall semester " for personal reasons ." 9. A so-called fish grade EPDM ( ethylene propylene diene monomer ) is recommended. 10. Allylic bromination with elimination of two equivalents of hydrogen bromide to give the diene product.
