We have succeeded in the synthesis of a 2-germaazulene stable in solution, in which the carbon atom at the 2-position of azulene is replaced by a germanium atom, the fourth period element in Group 14. The properties of the obtained 2-germaazulene were verified both experimentally and theoretically, indicating its sufficient aromaticity. In comparison with the parent azulene, significant differences
我们成功合成了在溶液中稳定的 2-germaazulene,其中 azulene 2 位上的碳原子被第 14 族的第四周期元素
锗原子取代。所得 2-germaazulene 的性质经实验和理论验证,表明其具有足够的芳香性。与母体 azulene 相比,发现其轨道
水平、电荷分布和所得性质存在显着差异。
