    • The invention provides new methods for synthesis of large boron hydride clusters, e.g., boron hydride molecules of the formula B n H m where 5=n=96 and m=n+8, wherein m and n satisfy the electron counting rules of macropolyhedral boranes. The invention is particularly useful for synthesis of octadecaborane (B 18 H 22 ). Preferred methods of the invention include iteratively generating a conjugate acid from a salt of the [B a H b ] c- or [B n + 2 H m-4 ] 2- anion followed by degradation under conditions conducive to concentrating and drying of the conjugate acid to provide a borane B n H m and residual salt of the [B a H b ] c- or [B n + 2 H m-4 ] 2- anion which is reused in the method of synthesis. The invention further provides isotopically enriched boranes, particularly isotopically enriched 10 B 18 H 22 and 11 B 18 H 22 .
    • 本发明提供了用于合成大的硼氢化物簇的新方法,例如式B的氢化硼分子,其中5 = n = 96和m = n + 8,其中m和n满足大面积硼烷的电子计数规则。 本发明特别可用于合成十八硼烷(B 18 H 22 H 22)。 本发明的优选方法包括迭代地从[B]或(B)的盐中产生共轭酸 在有助于浓缩和干燥共轭物的条件下降解,然后在有助于浓缩和干燥共轭物的条件下降解 酸以提供硼烷B n H n H m,并且[B a a a H b B]的残余盐 > - - - - - - - - - - - - - - - - - - - - - - - - - - 在合成方法中重复使用。 本发明进一步提供同位素富集的硼烷,特别是同位素富集的硼烷,特别是同位素富集的硼烷,特别是同位素富集的硼烷, 18 H 22。
