Pentaborane(9), B5H9, is shown to be a useful source for the production of higher boron hydride systems. Investigation of the reaction of B5H9 with sodium hydride or potassium hydride in THF or glyme to produce the tetradecahydrononaborate(1-) anion, [B9H14]-, is reported in detail, and evidence is given for reaction pathways. This anion is also obtained from the reaction of NaI with B5H9. When generated in situ from B5H9, [B9H14]- is an intermediate in the syntheses of a number of other higher boron hydride systems: B9H13·L ligand adducts, n-B18H22, B10H14, nido-5,6-C2B8H12, and nido-5,6-(CH3)2-5,6-C2B8H 10. The synthesis of B10H14 reported here is an improved procedure over the earlier reported preparation from B5H9, and the preparations of nido-5,6-(CH3)2-5,6-C2B8H 10 and nido-5,6-C2B8H12 are new syntheses.
