The reactivity of nitroethylene and ethylene in a Diels-Alder reaction should be compared. Concept introduction: Diels-Alder reaction is a [ 4+2 ] cycloaddition reaction, in which a π-system having four atoms (diene) and a π-system having two atoms (dienophile) are undergoing in cycloaddition reaction and producing a substituted cyclohexene . The reactivity of dienophiles are depending upon the substituents attached to it, the electron-withdrawing substituent such as carbonyl groups or nitro-groups activate the dienophile for Diels-Alder reaction by making the dienophiles more reactive to dienes. To compare: the reactivity of nitroethylene and ethylene in a Diels-Alder reaction.
