Studies on Syntheses and Derivatives of Boron Hydride Systems

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 (B11H11AlCH3)2, B11H11PCH3, and B10H12PCH3 derived form (B11H14) have been synthesized and characterized. Alkali metal reductions of B5H9 and THFBH3 result in the dianions (B5H9)2 and (BH3)2. 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.
