本文论述了非经典碳正离子这一问题的有关争论,是根据近期评论译述的。争论的中心是,全去甲莰正离子是在C—C或C—H键电子的σ-参与下形成非经典的离子,还是如Brown所指出的那样,是一个定域的经典离子,但受到立体的张力效应,从而加速了它在溶剂解中的形成。 This article discusses the controversy over the issue of non-canonical Cations, based on recent reviews. At the heart of the debate is whether all normodinium ions form nonclassical ions under the σ-participation of the C-C or C-H bond electrons or, as Brown pointed out, a localized classical ion but By three-dimensional tension effect, thus accelerating its formation in the solvent solution.
