标题:Isotopically-enriched boranes and methods of preparing them
发明人：SPIELVOGEL BERNARD; COOK KEVIN S

摘要: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 .
