第一稳定的中性锗芳香族化合物，即，通过溴代锗烷4与二异丙基氨基锂的反应，成功地合成了具有有效空间位阻保护基的2-锗萘1a，即2，4，6-三[双（三甲基硅基）甲基]苯基（Tbt）。通过核磁共振、紫外-维斯光谱、拉曼光谱、X射线晶体学分析和理论计算，对1a的分子结构和芳香性进行了讨论。
The first stable neutral germaaromatic compound, i.e., the 2-germanaphthalene 1a bearing an efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt), was successfully synthesized by the reaction of the corresponding bromogermane 4 with lithium diisopropylamide. The molecular structure and aromaticity of 1a were discussed on the basis of its NMR, UV−vis, and Raman spectra, X-ray crystallographic analysis, and theoretical calculations.
