We report synthesis of dibenzoaluminepin as the first aluminepin, an aluminum analogue of borepin and gallepin. This compound contains one molecule of ethereal solvent on the Al atom, which adopts a tetrahedral geometry. The central 7-membered aluminepin ring has a boatlike conformation and was characterized by single-crystal X-ray diffraction, (1)H/(13)C NMR, and DFT studies. In addition, NICS, NBO, and theoretical calculations provide insight into the nature of the bonding and aromaticity of aluminepins.
我们报道了 dibenzoaluminepin 的合成,这是第一个 aluminepin,是 borepin 和 gallepin 的铝类似物。该化合物在 Al 原子上含有一个醚溶剂分子,采用四面体几何形状。中心的 7 元 aluminepin 环具有船形构象,并通过单晶 X 射线衍射、(1)H/(13)C NMR 和 DFT 研究进行了表征。此外,NICS、NBO 和理论计算深入了解了 aluminepins 的键合性质和芳香性。
