In recent years, the possible global 2D/3D aromaticity of carborane-fused cycles has been widely debated. While phosphorus heterocycles fused with carboranes are known, the 2D aromatic character in carborane-fused phospholes was only recently reported. However, our computational study found that these compounds lack 2D aromaticity. Instead, they should be viewed not as a fusion of an aromatic ring but as a fusion of an unsaturated ring with carboranes.
近年来，碳硼烷稠合环可能具有的全局二维/三维芳香性一直备受广泛争议。虽然与碳硼烷稠合的磷杂环是已知的，但碳硼烷稠合的磷茂中的二维芳香特性直到最近才被报道。然而，我们的计算研究发现这些化合物缺乏二维芳香性。相反，它们不应被视为芳香环的稠合，而应被视为不饱和环与碳硼烷的稠合。
