| 摘 要： | 卡宾的基态有单线态和三线态两种状态。本文用HMO法的近似解说明了卡宾是以单线基态还是以三线基态存在的原因,同时也比较满意地解释了卡宾弯曲空间结构的特点,以及环状共轭卡宾的亲核或亲电反应性质。本文认为,卡宾中心碳原子是SP~2杂化。卡宾的基态是单线态还是三线态取决于卡宾中心碳原子的非键P轨道与相邻原子的P轨道的相互作用以及P电子的数目。

| Abstract: | The basic state of carbene is singlet or triplet.In the paper,the cause that the basic state of car- bene is singlet or triplet,and its non-linear steric structure is explained,and is predicted on the basis of HMO theory.The nucleophilicity or electrophilicity of cyclic conjugated carbene is considered.This pa- per presents that the central carbon atom of carbene is to use SP~2 hybrid orbitals to form covalent bonds.That the basic state of carbene is singlet or triplet depends on interaction of the nonbonding p or- bital of the central carbon atom of carbene with the P orbitals of the adjacet atom,and the number of P electrons. |
