Nitrosation of dodecahydro-closo-dodecaborate anions with nitrous acid in an aqueous solution and with isoamyl nitrite and nitrosyl chloride in nonaqueous solutions was studied. The main reaction product is the mononitrosoundecahydro-closo-dodecaborate anion. Conditions were selected for the preparation of the nitroso-substituted anion in the highest yield as alkylammonium, tetraphenylphosphonium, and alkali-metal salts. The salts were studied using IR, UV, and 11B NMR spectroscopy.
