The retro-Diels–Alder reaction (rDA reaction) is the reverse of the Diels–Alder (DA) reaction, a [4+2] cycloelimination. It involves the formation of a diene and dienophile from a cyclohexene. It can be accomplished spontaneously with heat, or with acid or base mediation. In principle, it becomes thermodynamically … See more Prevailing mechanism The retro-Diels–Alder reaction proper is the microscopic reverse of the Diels–Alder reaction: a concerted (but not necessarily synchronous), pericyclic, single-step process. Evidence … See more A few rDA reactions occur spontaneously at room temperature because of the high reactivity or volatility of the emitted dienophile. Most, however, require additional thermal or … See more Typical conditions Internal energy is the only factor controlling the extent of rDA reactions, and temperature is usually the only variable cited for these reactions.
