Abstract

By reacting nitrilium derivative of the closo-dodecaborate anion, Bu4N[B12H11N≡CR] (where R = Me, Et, nPr, iPr, p-tolyl), with lithium aluminum hydride (LiAlH4), N-alkylammonium derivatives of the closo-dodecaborate anion, and Bu4N[B12H11NH2CH2R], were obtained. The reduction reaction procedure was optimized, achieving yields close to quantitative (90–95%). The structure of the compound Bu4N[B12H11NH2CH2CH3] was determined using X-ray structural analysis. It was found that substituting lithium aluminum hydride (LiAlH4) with sodium borohydride (NaBH4) leads to the same products but only upon heating, while the reaction with LiAlH4 proceeds at room temperature.

氢化铝锂还原 [B12H11NCR]- 阴离子中的三键：合成 N-单烷基氨代闭-十二硼酸盐的新方法

用氢化锂铝（LiAlH4）与络合剂十二硼酸阴离子的腈衍生物 Bu4N[B12H11N≡CR]（其中 R = Me、Et、nPr、iPr、对甲苯基）反应，得到了络合剂十二硼酸阴离子的 N-烷基铵衍生物和 Bu4N[B12H11NH2CH2R]。还原反应过程经过优化，收率接近定量（90-95%）。化合物 Bu4N[B12H11NH2CH2CH3] 的结构是通过 X 射线结构分析确定的。研究发现，用硼氢化钠（NaBH4）代替氢化铝锂（LiAlH4）会产生相同的产物，但只有在加热时才会产生，而用 LiAlH4 进行的反应则在室温下进行。
