环加成反应是有机化学中的一类重要反应.本文试用次级轨道效应,定性地讨论环加成反应中的立体选择性,并用含有次级轨道作用项的微扰方程半定量地解释其区域选择性.
Cycloaddition reaction is a kind of important reaction in organic chemistry.In this paper, the secondary orbital effect is used to qualitatively discuss the stereoselectivity in the cycloaddition reaction, and semi-quantitatively explained by the perturbation equation containing the action term of secondary orbit Regional selectivity.
