E xpeerriimmeenntt:: ddiieells-alder reaction diels-alder cycloaddition reactions have proven to be quite useful routes to form new six-membered ring structures.

Diels-alder reacton introduction in this reaction, a diene will be reacted with a dienophile to generate a new cyclohexene ring in a diels-alder reaction. The purpose of this experiment was to demonstrate the formation of six-membered rings by cycloaddition, also known as a diels-alder reaction in a cycloaddition reaction, a 1,3-diene reacts with an alkene, or dienophile, to produce a six-membered ring. Experiment 3: diels-alder exo or endo background a diels-alder cycloaddition reaction can result in either and/or both endo and exo-products.
