eng	Electron-rich 10-vertex Carborane Clusters: Synthesis and Reactivity	The chemistry of heteroborane clusters is an inseparable part of modern inorganic chemistry. Polyhedral heteroboranes are formed by electron-deficient two-electron three-centred bonds, with the overall charge being neutral or negative. Despite tens of thousands of published compounds, the positively charged species remained elusive for a long time. In 2021, we described the first thermally robust cationic carboranes supported by bulky N-heterocyclic carbenes.1 In this work, the reactivity of 10-vertex closo-dicarba-boranes with different N-heterocyclic and mesoionic carbenes to 10-vertex nido-dicarboranes-bis-carbene adducts will be discussed as along with their structural rearrangements to thermodynamically stable products. The reactivity of such electron-rich clusters with various acids, transition metal complexes, and main group compounds will be presented as well.
