在许多有机化学反应过程中,常有不稳定的碳正离子活性中间体产生。对于这类反应的主要产物,以及在相同条件下某些反应间的相对反应速度的大小,在很大程度上往往取决于瞬时碳正离子的相对稳定性。因此,瞬时碳正离子的相对稳定性大小是有机化学工作者所普遍关心的问题。蒋庆云用“轨道成分及能量对比法来判断某些处于同一反应体系中的瞬时碳正离子相对稳定性,说明了一些问题。但是用此
In many organic chemical reactions, often unstable carbocationium active intermediates. The size of the major products of this type of reaction, and the relative rate of reaction between some of the reactions under the same conditions, is very much dependent on the relative stability of the instantaneous carbon-cations. Therefore, the relative stability of instantaneous carbon-cations is a matter of general concern to organic chemists. Jiang Qingyun "Track composition and energy contrast method to determine the relative stability of some of the instantaneous carbon positive ions in the same reaction system, to illustrate some of the problems. But with this
