摘要: 我们曾研究了硼氢化钾与四乙基氯化铵在一定量水存在下的热解反应,制得了B10H102-、B12H122-等多面体硼氢化合物[1],并提出了热解反应的历程[2]。在少量水存在下,通过三烷基苄基氯化铵与硼氢化钾反应,合成了四氢硼酸三烷基苄基铵R3(C6H5CH2)NBH4。但热解该类型四氢硼酸盐时,得不到B10H102-、B10H122-等多面体硼氢化合物,而是苄基与氮相连的C—N键断裂形成的R3N·BH3配合物和甲苯[3]

Abstract: In this work , the reactioin of KBH4 with C5H5FeC5H4CH2NMe2(R)Xin aqueous solution is investigated. It is found that when Ris an electron-drawing group, the product is a quaternary ammonium salt of BH4- when Ris an electron-donating group or H , the product is a complex of BH3. The compositions of the products were identified by elemental analyses and IRspectrometry. The reaction provides a simple , high-yield synthetic procedure for quaternary ammonium salts of BH4- and complexes of borane.
