Abstract
The invention provides new methods for synthesis of large boron hydride clusters, e.g., boron hydride molecules of the formula BHwhere 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 (BH). Preferred methods of the invention include iteratively generating a conjugate acid from a salt of the [BH]or [BH]anion followed by degradation under conditions conducive to concentrating and drying of the conjugate acid to provide a borane BHand residual salt of the [BH]or [BH]anion which is reused in the method of synthesis. The invention further provides isotopically enriched boranes, particularly isotopically enrichedBHandBH.
