Synthesis of carbocation salts of boron cluster anions [B10H10]2− and [B12H12]2−

A series of closo-decaborates and closo-dodecaborates as carbocation salts was obtained by the reaction of Kat2[B n H n ] (n = 10, 12; Kat = Na, K, Ag) with tertiary alkyl halides t C4H9Cl, 1-AdBr, and (C6H5)3CCl. The prepared compounds were identified by IR and 1H, 11B, 13C NMR spectroscopy.
