網頁2024年4月12日 · A self-accelerating Diels–Alder reaction was developed based on the [4+2] cycloaddition of sym-dibenzo-1,5-cyclooctadiene-3,7-diyne (DIBOD) and ortho-quinone compounds. In this reaction, the cycloaddition of ortho-quinone with the first alkyne of DIBOD activates the second alkyne, which reacts with ortho-quinone at a rate constant … 網頁Diels-Alder reactions are concerted, stereospecific, and follow the endo rule. The Diels-Alder reaction is a concerted reaction, this means it occurs in only one step. Moreover, … st thomas hickman hospital centerville tn

In contrast, when an unsymmetrical diene and an unsymmetrical dienophile combine in a Diels–Alder reaction, it may afford two constitutionally isomeric cycloadducts. st thomas hickman clinic
