In contrast to the well-investigated sila- and germa-aromatic compounds, very few aromatic compounds containing tin have been reported. Specifically, no stable example of monomeric stannabenzene, that is, the tin analogue of benzene, the simplest aromatic compound, has been isolated until now. In this work, a tin analogue of the phenyl anion, the stannabenzenyl anion, was successfully isolated by utilizing the same strategy as employed for the germanium system. Stannabenzenylpotassium was characterized by X-ray crystallography, NMR ( H, C, and Sn) and UV/Vis spectroscopy, together with theoretical calculations.
与研究充分的硅和锗芳族化合物相比，含锡的芳族化合物报道得很少。具体来说，迄今为止，尚未分离出单体的芳基锡化合物，即最简单的芳族化合物苯的锡类似物。在这项工作中，芳基阴离子的锡类似物，即苯基金属阴离子，通过利用与锗体系相同的策略成功分离出来。通过 X 射线晶体学、NMR（H、C 和 Sn）和 UV/Vis 光谱以及理论计算对苯基金属钾进行了表征。
