The Diels-Alder reaction involves a concerted movement of 2 pairs of electrons in the conjugated diene and 1 pair of electrons in the dienophile in one step. The Diels-Alder reaction between a conjugated diene and dienophile produces a cyclohexene adduct. The Diels-Alder reaction of (2Z,4E)-hepta-2,4-diene will be slower than that of (2E,4E)-hepta-2,4-diene. The conjugated diene must be able to adopt a s-cis conformation to participate in the Diels-Alder reaction. Tertiary carbocation is less stable than secondary carbocation, which is less stable than primary carbocation. Methyl cation is the most stable
