'Al'l about F: Aluminum chlorofluoride (ACF) catalyzes the hydrodefluorination, as well as Friedel-Crafts reactions of fluorinated methanes in the presence of Et3SiH. A surface-bound silylium-ion-like species is considered to be a crucial intermediate in achieving the C-F bond cleavage. Copyright
Exhaustive chlorination of [B12H12]2- without chlorine gas and the use of [B12Cl12]2- as a supporting anion in catalytic hydrodefluorination of aliphatic C-F bonds

The fully chlorinated closo-dodecaborate salt Cs2[B 12Cl12] was prepared in high yield from Cs 2[B12H12] and SO2Cl2 in acetonitrile at refluxing temperature. [Ph3C]2[B 12Cl12] was obtained by simple metathesis reactions. Catalytic hydrodefluorination of benzotrifluoride sp3 C-F bonds was accomplished using [Ph3C]2[B12Cl12] as a precatalyst and Et3SiH as a stoichiometric reagent. Full consumption of the sp3 C-F bonds in p-FC6H 4CF3 and C6F5CF3 with a turnover number up to 2000 was achieved.
