摘要: 利用ABEEM-σπ模型对Diels-Alder反应进行了理论研究,通过计算原子和π键区域的局域软度值,应用局域软度理论对典型的Diels-Alder反应的较高立体选择性给出了合理解释.

Abstract: Diels-Alder reaction has a huge application value due to their high stereoselectivity.The reactive region of this kind of cycloaddition includes not only atoms but also the important π bond zones.In this article,we utilized the ABEEM-σπ model to research this kind of reactions,and through the regional softnesses of both the atoms and π bonds,which were calculated by this model,we interpret properly the stereoselectivity of the typical Diels-Alder reaction.

Key words: ABEEM-σ&pi, model, Diels-Alder reaction, Local softness
