The aryl-bridged disilyl cations 8 with an 1,8-naphthalenediyl backbone were synthesized and were identified by NMR spectroscopy. In addition the [B(C6F5)4]- salt of the tolyl-bridged cation 8b was characterized by X-ray crystallography.核磁共振波谱和结构数据表明二甲硅烷基阳离子 8 的芳烃离子性质。量子力学计算的结果证实了实验结果，模型阳离子 6 中电子密度的 Bader 型拓扑分析给出了芳基桥联二甲硅烷基阳离子 6 和 8 中键合的精细图像。
The aryl-bridged disilyl cations 8 with an 1,8-naphthalenediyl backbone were synthesized and were identified by NMR spectroscopy. In addition the [B(C6F5)4]- salt of the tolyl-bridged cation 8b was characterized by X-ray crystallography. The NMR spectroscopic and the structural data indicate the arenium ion nature of disilyl cations 8. Results of quantum mechanical computations corroborate the experimental findings, and a Bader-type topological analysis of the electron density in model cation 6 gives a refined picture of the bonding in aryl-bridged disilyl cations 6 and 8.
