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

将硼原子嵌入到芳香π体系中不仅是芳香性历史的一个组成部分，而且还提供了在材料科学和催化方面的许多有价值的应用。我们的研究小组最近开发了未知的中性1，4-diborabenzenes和前所未有的9，10-diboraanthracenes与开壳单重基态的实验方法。这些分子是非常富电子的硼-π-芳族化合物，具有出色的π供体能力，这允许许多有趣的初步结果，包括d-区和f-区金属的不常见的π络合物。该项目的目标是这些迷人的系统，它们的精心制作，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.
