环式结构体系中的双碳正离子

Carbodications in the Cyclic and Polycyclic System

在某些环式结构体系中,由于某些轨道的相互作用使正电荷离域,从而克服正电荷间的相互排斥形成长寿命的双碳正离子。本文介绍苯双碳正离子,双环[m.n.p]桥头双碳正离子、去氢金刚烷基双碳正离子及宝塔烷双碳正离子的生成、检测、性能及理论处理。

Some carbodications in the cyclic or polycyclic system can be characterized understable ion solution conditions,mainly due to the interaction of both cation centers through oskeleton,π orbitals and various aromatic stabilization.In the present paper,the syntheses,structure,properties and some theoretical aspects of benzene dication,[m.n.p]propellanedications,dehydro-adamantane dication,pagodane dication and sandwiched bishomoaromaticdication are reviewed.
