【摘要】 通过硼烷阴离子网-B₃H₈^-和闭-B₁₀H₁₀^2-1与一系列卤化铵反应合成出十五种新的硼烷阴离子铵盐。这些新化合物均经元素分析和红外光谱鉴定。它们的差热分析结果表明:B₁₀H₁₀^2-铵盐的热稳定性高于B₃H₈^-铵盐;在季铵离子中导入氨基以后,化合物的热稳定性降低,并且导入的氨基愈多,化合物愈不稳定。更多还原

【Abstract】 15 new borane anion ammonium salts have been synthesized by the reaction of borane anion (arachno-B3H8- or closo-B10H102-) with various ammonium halides. All of the compounds were confirmed by elemental analysis and IR. The DTA results for these compounds indicated that the thermal stabilities of the B10H102- salts are higher than those of B3H8-, and the thermal stabilities of these compounds become lower when an alkyl group in the ammonium cation is substituted by an amino group. The greater the number of amino groups, the more the thermal stability decreases,更多还原
