Cumulenes, including allene, ketenimine, and ketene, contain characteristic allenic or heteroallenic bonds.They can be employed as dienophiles in Diels-Alder type reactions.The activation energies of the Diels-Alder reaction between cyclopentadiene and either the C=C bond or the other C=X (X =C, N, or O) bond in cumulenes have been predicted by G3B3, CBS-QB3, M06-2X and B3LYP models.
