A kinetic study of Diels-Alder additions between norbornene derivatives acting as dienophiles and the dienes tropone, perchlorocyclopentadiene and 9,10-dimethylanthracene is presented. The results suggest that tropone thereby acts as an electron acceptor, classifying these reactions then as Diels-Alder additions with ‘inverse electron demand’.
动力学研究了降冰片烯衍生物作为二烯亲和物与二烯tropone,全氯环戊二烯和9,10-二甲基蒽之间的Diels-Alder加成反应。结果表明,托克酮因此充当电子受体,将这些反应分类为具有“反电子需求”的狄尔斯-阿尔德加成物。
