碳正离子、碳负离子作为最常见有机反应活性中间体,涉及反应类型众多,易出现中间体重排,一直是有机化学的重点和难点。文章从概念、结构、稳定性、生成和湮灭等五个方面对这两种有机活性中间体分别加以介绍,便于对比掌握这两类有机活性中间体的特性与反应。

As the most common organic reactivity intermediate, C (superscript +) and C (superscript 3 +) ions are involved in many types of reactions and intermediate rearrangements are prone to occur. It has always been the focus and difficulty of organic chemistry. The article introduces the two kinds of organic active intermediates from the aspects of concept, structure, stability, generation and annihilation so as to compare and grasp the characteristics and reactions of the two types of organic active intermediates.
