The vigour of two-parent progenies was likely to be similar. bimolecular nucleophilic substitution with allylic rearrangement 双亲本子代的生活力多半是相似的。含烯丙型重排双分子亲核取代
A method for determining Huckel-Hubbard ( H-H) parameters is proposed, and the H-H theory is extended to analyze [ 2, 3] sigmatropic rearrangements including Witting rearrangement, sulphur ylide rearrangement and allylic sulfoxide rearrangement. 本文提出一种确定Hückel-Hubbard(H-H)参数的方法,并将H-H理论首次推广用于Witting重排、硫叶立德重排、烯丙基亚砜重排等[2,3]σ键迁移重排反应的研究。
