摘要: 硼簇化合物的合成路线长,原料昂贵和产率低,使硼簇物化学的基础研究和开发应用受到了很大的限制.80年代前苏联科学家对合成B12H122-方法做了改进,用非挥发性的(C2H5)3N·BH3代替剧毒硼烷,产率高达93.5%~95%[1],但需要特殊实验装置,且不适用于大量制备.

关键词: 十二硼烷二钠盐, 合成

Abstract: An improved method for preparation of closo dodecaborate B12H122- with yield of 89.8% is described. The improved reaction conditions and separation procedure of the product for thermal decomposition of B3H8- to B12H122- in diglyme are given. The method is suitable for routine preparation.

Key words: disodium dodecahydrododecaborate, synthesis
