Abstract—Iodination, bromination, and thiocyanation reactions of the potassium salt K⁺[7,8-C₂B₉H₁₂] are
investigated during diaphragm electrolysis. The B(9)-monosubstituted derivatives [9-X-7,8-C₂B₉H₁₁] (X=I,
SCN) and disubstituted derivatives [9,11-X₂-7,8-C₂B₉H₁₀] (X = Br, I) are obtained as alkylammonium salts.
The composition and structure of these substances are confirmed by data from elemental analysis and IR and
NMR (¹H and ¹¹B) spectroscopy.

Key words: carboranes, potassium dodecahydro-7,8-dicarba-nido-undecaborate, halogenation, thiocyanation,
electrochemistry, diaphragm, nuclear magnetic resonance
