31. When the substituents of the dienophile are exo, there is no interaction between those substituents and the diene . 32. Diene did not specifically mention detainees held at a U . S . naval base at Guantanamo Bay in Cuba.33. This diene is also not expected to act as a diene in a Diels Alder reaction due to its structure. 34. This diene is also not expected to act as a diene in a Diels Alder reaction due to its structure. 35. His most notable work was done with Kurt Alder on the Diels Alder reaction, a method for diene synthesis. 36. The amount of nickel used should be low as a direct alkene coupling to a diene is a side reaction. 37. Diene 's visit to this former British colony followed a tour of Guyana, where the racial dynamic is similar.38. The diene , the tetrazine, by virtue of having the additional nitrogens, is a good diene for this reaction. 39. The diene, the tetrazine, by virtue of having the additional nitrogens, is a good diene for this reaction. 40. Under these conditions singlet oxygen is generated which reacts in a Diels Alder reaction with the diene system in the terpinene.
