The first stable neutral stannaaromatic compound, 2-stannanaphthalene , was synthesized by taking advantage of an extremely bulky and efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt). The molecular structure and aromaticity of were discussed on the basis of X-ray crystallographic analysis, NMR, UV-vis, and Raman spectroscopy, cyclic voltammetry, and theoretical calculations. 2-Germanaphthalene , which has a framework similar to that of , was synthesized for comparison, and systematic elucidation was made for the properties of 2-metallanaphthalene systems containing a heavier group 14 element (Si, Ge, or Sn).
利用一个极其庞大且高效的空间保护基团2,4,6-三[双(三甲基硅基)甲基]苯基(Tbt)合成了首个稳定的中性锡芳香族化合物2-锡萘。基于X射线晶体学分析、核磁共振、紫外可见光谱和拉曼光谱、循环伏安法以及理论计算,对其分子结构和芳香性进行了讨论。合成了具有与2-锡萘类似骨架的2-锗萘用于比较,并对含有较重第14族元素(硅、锗或锡)的2-金属萘体系的性质进行了系统阐释。
