Ten new salts that pair triazolium and imidazolium cations with c/oso-icosahedral anions [B12H12]2 and [B 11H12]-were synthesized in water solvent using an open-air, benchtop method. These unreported [Heterocyclium] 2[B12H12] and [Heterocyclium][CB 12H12] salts extend reports of [Imidazolium][CB 12H12] and [Pyridinium][CB12H12] salts that were synthesized in anhydrous organic solvents under an inert atmosphere with glovebox or Schlenk techniques. Spectroscopic data, melting points, and densities are reported for each salt. Single-crystal X-ray structures are provided for the five new [B12H12] 2- salts.

Triazoles have been successfully used as building blocks to create "fully organic" ILs featuring on both sides organic ions, i.e., 1,2,3- or 1,2,4-triazolide anions and 1,2,4-triazolium or imidazolium cations. Glass transition temperatures, densities and viscosities of these ILs were determined. Their electrochemical and thermal stability, and also conductivity, are higher than those for known ILs.
Pairing heterocyclic cations with closo-icosahedral borane and carborane anions, II: Benchtop alternative synthetic methodologies for binary triazolium and tetrazolium salts with significant water solubility

Two efficient processes for the synthesis of 12 relatively water-soluble binary triazolium and the first tetrazolium borane [B12H12] and carborane [CB11H12] salts by a one-step, open-air metathesis reaction have been developed. First, a combination of exhaustive trituration of the two solid reactant salts with refluxing anhydrous acetonitrile followed by flash filtration through a plug of silica gel afforded excellent recovery for a broad series of otherwise water-soluble heterocyclium salts. Second, an alternative aqueous metathesis, driven to completion by precipitation of silver halides, followed by removal of water, redissolution in acetonitrile, and filtration through a silica-gel plug, also yielded such heterocyclium borane and carborane salts. Mixed 1:1 dication heterocyclium borane salts were first synthesized using this second procedure, and one example showed melting-point depression behavior. Taylor & Francis Group, LLC.
