It has been computationally proposed that there are more than 200 possible isomeric structures for the CH molecule, among which benzene (CH) represents the most thermodynamically stable molecule and its chemistry has been extensively developed. Three benzene valence isomers (CR), namely, prismane, Dewar benzene, and benzvalene, have also been synthesized to date. Incorporation of heteroatoms in the skeletal frameworks allows access to inorganic analogues of benzene and its valence isomers, which have attracted considerable attention due to their peculiar structural and electronic features. Experimentally, more than 30 examples of inorganic benzene and its valence isomers have been developed and characterized so far. In this contribution, their synthesis and characterization, as well as their stability and chemical properties, are discussed.
据计算，CH 分子可能存在 200 多种同分异构体，其中苯（CH）代表热力学最稳定的分子，其化学性质也得到了广泛的研究。迄今为止，三种苯的价态异构体（CR），即轮烷、杜瓦苯和苯并戊二烯，也已被合成。在骨架框架中引入杂原子可以得到苯及其价态异构体的无机类似物，由于其特殊的结构和电子特性，这些类似物引起了相当大的关注。迄今为止，已有 30 多个无机苯及其价态异构体的实例被开发和表征。在本文中，讨论了它们的合成和表征，以及它们的稳定性和化学性质。
