| Abstract: | Six new solvated proton salts of highly halogenated carborane anions, [H(solvent),] [carborane] (carborane = 1‐R‐CB11‐Y5X6‐(R=H, Me; X, Y=CI, Br, I), 1‐H‐CB9Br9?) were prepared from the salt metathesis reaction of Ag(carborane) and HO in high yields. Single‐crystal X‐ray analyses show that they are all discrete molecules in the solid‐state. The number of the solvated molecules surrounding H+ ion can not be determined with the knowledge of the size and substituents of the carborane anions. These salts provide convenient weighable sources of Brønsted acid reagents having a wide range of acidities and good thermal stabilities. TGA results indicate that the solvated molecules (water or organic molecules) in the cations [H(solvent)n]+ can be removed under high temperature and high vacuum conditions to give superacidic materials H(carborane) which can protonate olefin. |
