Neutral diborabenzenes – highly electron-rich systems for classical arene-type reactivity, bond activation, and catalysis

在芳香族聚酰亚胺体系中嵌入硼原子不仅是芳香性发展史中不可或缺的一部分，而且在材料科学和催化方面也提供了许多有价值的应用。我们的研究小组最近开发了未知的中性1，4-二硼苯和史无前例的9，10-二硼并茂的开壳单重态基态的实验方法。这些分子是极富电子的Bora-pi芳香族化合物，具有突出的pi给体能力，这使得一些有趣的初步结果成为可能，包括d-嵌段和f-嵌段金属的罕见的pi络合物。这个项目的目标是这些令人着迷的系统，它们的精致，以及在许多不同方向上充分利用它们非常有前途的反应性。

Embedding boron atoms into aromatic pi systems has not only been an integral part of the history of aromaticity, but also provided access to numerous valuable applications in materials science and catalysis. Our research group recently developed experimental access to unknown neutral 1,4-diborabenzenes and unprecedented 9,10-diboraanthracenes with open-shell singlet ground states. These molecules are extremely electron-rich bora-pi-aromatics with outstanding pi donor capabilities, which permitted a number of interesting preliminary results including uncommon pi complexes of the d-block and f-block metals. This project targets these fascinating systems, their elaboration, and the full exploitation of their very promising reactivity in a number of different directions.
