有机化合物苯、萘、蒽都是大家所熟悉的一类含有苯环结构的芳烃,都具有不同程度的芳香性。除此之外.(?)、(?)、(?)+轮烯、二茂铁等也同苯型芳烃一样,具有芳香性,因此也归到芳香族化合物,并具体称之为非苯型芳烃。这些非苯型环多烯及环多烯离子,从结构上如何认证为芳烃呢?人们通常用Hückel规则来判断、解释。凡符合此规则的分子,就具有芳香性,否则就不具有芳香性。那么为什么一个化合物结构符合Hückel规则,它就具有芳香性?
Organic compounds benzene, naphthalene, anthracene are all familiar class of benzene ring structure of aromatic hydrocarbons, all have varying degrees of aromaticity. In addition, (?), (?), (?) + Annulene, ferrocene and the like aromatic benzene, aromatic, and therefore also returned to the aromatic compounds, and specifically called non-benzene Aromatics. These non-benzene ring polycyclic polycyclic ring and polyene ions, from the structure of how to be certified as aromatic? People are usually used Hückel rules to judge, explain. Those who meet the rules of molecules, it has aromatic, otherwise it does not have aromatic. So why a compound structure in line with Hückel rules, it is aromatic?
