  4. C–H functionalization of undecahalogenated carborane anions, [HCB 11 X 11 − ] (X = Cl, Br, I), is performed with Cs 2 CO 3 in acetonitrile. We show that the requisite Cl, Br and I carborane dianions can all be efficiently accessed with Cs 2 CO 3 . The utilization of Cs 2 CO 3 eliminates the complications associated with competing E2 elimination reactions providing an efficient, more functional group tolerant, and broader scope than previously reported. The ensuing functionalized cages provide potential synthons for constructing advanced materials and other molecular architectures for various applications.

  5. The current research on cation-intercalation and conversion-type cathode materials for rechargeable aluminum batteries (RABs) is discussed in this critical review. The experimental evidence for Al 3+ intercalation in transition metal oxides, chalcogenides, MXene, and Prussian blue analogues in both chloroaluminate ionic liquids and aqueous electrolytes is analyzed to identify the true reaction mechanisms. Chevrel phase molybdenum sulfide (Mo 6 S 8 ) is the only proven intercalation material for RABs with unambiguous evidence, different understandings of the Al 3+ intercalation mechanism in Mo 6 S 8 are discussed. For conversion-type cathode materials, the discussion is focused on the conversion mechanism of metal chalcogenides, and the unique reversible oxidation mechanism of sulfur and selenium enabled by the chloroaluminate ionic liquid electrolytes. The reaction mechanisms of organic cathode materials are also discussed.
