Reaction of NaBH3CN with HCl in THF gave mainly NaBH3CNBH2CN, whereas in Me2S quantitative formation of BH2CN was observed. In dimethyl sulfide BH2CN exists in monomeric or dimeric form as Me2S complexes in an equilibrium with oligomers. These compounds are converted by amines into BH2CN complexes in nearly quantitative yield, and treatment with lithium cyanide gives LiBH2(CN)2. The reaction of the
NaBH 3 CN与HCl在THF中的反应主要得到NaBH 3 CNBH 2 CN,而在Me 2 S中观察到BH 2 CN的定量形成。在
二甲基硫醚中,BH 2 CN以单体或二聚体形式作为Me 2 S络合物与低聚物平衡存在。这些化合物被胺以几乎定量的产率转化为BH 2 CN络合物,并用
氰化
锂处理得到LiBH 2(CN)2。相应的
溴硼烷的Me 2 S配合物与AgCN的反应生成异
氰硼酸酯AgBH n(NC)4- n(n= 1,2),其可以容易地转化为钠盐,通过热异构化将其转化为
氰基
硼酸盐。二-和tricyanohydroborates是对酸非常稳定,并且BH 3 CNBH 2 CN -离子显著比BH更稳定的3 CN -离子。在N碱存在下进行
溴氧化时,LiBH 2(CN)2得到N-碱·BH(CN)2络合物和LiBH 2(CN)CNBH(CN)2。NaBH(NC)3转化为C 5 N 5 N·BH(NC)2
