WebThe initial Diels-Alder reaction involvee is not drawn).e triple bond, so the adduct retains a double bond at that location. This double bond could still serve as a dienophile, but in the present case the diene is sufficiently hindered to retard a second cycloaddition. The quinone dienophile in reaction F has two dienophilic double bonds. WebCumulated dienes have the double bonds sharing a common atom. The result is more specifically called an allene. Conjugated dienes have conjugated double bonds …
