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
第一个稳定的中性锡烷基芳族化合物2-stannanaphthalene是利用一个非常庞大和有效的空间保护基团2,4,6-三[双(三(三甲基甲硅烷基)甲基]苯基(Tbt)合成的。在X射线晶体学分析,NMR,UV-vis和拉曼光谱,循环伏安法和理论计算的基础上,讨论了其分子结构和芳香性。合成了具有相似于2的骨架的2-锗金属萘进行比较,并系统地阐明了含有更重的14族元素(Si,Ge或Sn)的2-metallanaphthalene系统的性能。
