Résumé: An original method for synthesis of a water-soluble derivative of the 1,2-[B12H10(OH)2] 2– boron cluster anion using alkaline hydrolysis of the products of interaction of bis(tetrabutylammonium) dodecahydro-closododecaborate (2–) with the melt of benzene-1,2-dicarboxylic acid in an inert atmosphere is developed. The synthesized compounds were identified with the help of the elemental analysis and IR and 11B spectroscopy of the nuclear magnetic resonance (NMR). It is shown that regioselectivity under the considered synthesis condition depends on the geometry of the selected synthesis reagent, namely, benzene-1,2-dicarboxylic acid.
