Icosahedral -dodecaboranes have the ability to accept two electrons, opening into a dianionic -cluster. This transformation can be utilized to store electrons, drive bond activation, or alter coordination to metal cations. In this feature article, we present cases for each of these applications, wherein the redox activity of carborane facilitates the generation of unique products. We highlight the effects of exohedral substituents on reactivity and the stability of the products through conjugation between the cluster and exohedral substituents. Futher, the utilization of the redox properties and geometry of carborane clusters in the ligand design is detailed, both in the stabilization of low-valent complexes and in the tuning of ligand geometry.
二十面体十二硼烷能够接受两个电子，形成双阴离子簇。这种转变可用于存储电子、驱动键活化或改变与金属阳离子的配位。在这篇专题文章中，我们介绍了这些应用中的每一种情况，其中碳硼烷的氧化还原活性促进了独特产物的生成。我们通过簇与外表面取代基之间的共轭作用，突出了外表面取代基对反应性和产物稳定性的影响。此外，还详细阐述了碳硼烷簇的氧化还原性质和几何结构在配体设计中的应用，包括低价配合物的稳定化和配体几何结构的调节。
