Abstract:

Studies of reaction pathways in the conversion of B5H9 to B9H14 resulted in maximizing the yield of B9H14 and close to quantitative synthesis of B11H14. The B9H13 dianion derived from B9H14 has been synthesized and characterized. The heteraboranes B11H11AlCH32, B11H11PCH3, and B10H12PCH3 derived form B11H14 have been synthesized and characterized. Alkali metal reductions of B5H9 and THFBH3 result in the dianions B5H92 and BH32. A cage expansion reaction has produced a 10 vertex arachino-C2B8 carborane. The lanthanides Yb, Eu, Sm reduce B10H14 to form lanthanide boranes precursors of lanthanide borides. Reduction of the boron nitride precursor Cl3B3N3H3 has been investigated. Pentaborane, borane anions, aluminaborane, phosphaborane, boron nitride precursor, lanthanide borane.
