WebApr 15, 2004 · The decision to split the review of the rDA reaction into two parts was based on the volume of literature encountered, as outlined in the Introduction to Part I. Active … 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. Thus, there are no conditions which can be regarded as "typical." For rDA … See more bishop felix orji
