根据三轨道作用法重点讨论了Diels-Alder反应中反应物轨道演变成产物轨道的过程, 演变结果与轨道对称守恒原理的结果基本相同. 量子化学计算证实了演变过程的合理性, 这表明在解释D-A反应方面轨道对称守恒原理比前线轨道理论更加合理可靠.

关键词: Diels-Alder 反应, 轨道对称守恒原理, 机理, 轨道相互作用, 前线轨道理论

The course by which valent orbitals of reactants evolve into valent orbitals of product in a Diels-Alder reaction has been discussed by using a three-orbital interaction method, and the evolutive result is in agreement with the principle of conservation of orbital symmetry. The rationality of the evolutive course has been approved by a quantum chemistry calculation, which indicates that the principle of conservation of orbital symmetry is more logical than frontier molecular orbital theory in interpreting a D-A reaction.

Key words: Diels-Alder reaction, principle of conservation of orbital symmetry, mechanism, orbital interaction, frontier molecular orbital theory
