  • Reactions of Group 13 and 14 Hydrides and Group 1, 2, 13 and 14 Organyl Compounds with ( <i>tert‐</i> Butylimino)(2,2,6,6‐tetramethylpiperidino)borane

    tmp−B(SnPh3)−NHtBu was formed showing an umpolung of the hydrostannylation. Organyllithium compounds provide access to N-lithiodiaminoboranes of the type tmp−BR−NtBu−Li. The stability of these compounds depends on the substituent R. The least stable compound was the B−tBu derivative followed by the B-methyl compound. However, in the presence of TMEDA tmp−BMe−NtBu−Li is sufficiently stable to allow reactions
    (叔丁基亚氨基)(2,2,6,6-四甲基哌啶基)硼烷 (1) 是一种高活性物质。它的 B≡N 三键插入硼烷的 B-H 键 R2BH,生成 tmp-BH-NtBu-BR2 类型的二硼胺(tmp = 2,2,6,6-四甲基哌啶基;R = H、Cl、Br ,或有机基)。Thexylborane 反应类似,但它的两个 B-H 键中只有一个用于 1 的硼氢化。然而,二卤硼烷 HB(Hal)2-SMe2 (Hal = Cl, Br) 产生 B-卤化产物 tmp-B(Hal) -NtBu-BH(Hal),而与 H2B(Hal)-SMe2 的反应通过竞争性硼氢化和卤化反应产生两种异构体的混合物。Tmp-BH-NtBu-AlH2 是从 1 和 AlH3-NMe3 获得的。它是一种固态二聚体,具有五配位的 Al 原子和 AlH2Al 桥。用 Me2SiHCl 实现 1 的氢化硅烷化,SiHCl3 或 Ph2SiH2

    bromide counter anion with either hexafluoroarsenate or hexfluoroantimonate anions revealed weak hydrogen bonds between the P‑H bonds of the boronium cations and the anions, that appeared through NMR studies to be retained in solution (where hydrogen bonding order was determined to be Br‑ > [SbF6]‑/[AsF6]‑). This was further demonstrated by comparison of solid-state structures and solution NMR data of

    3] undecane 1 through hydroboration of triallylborane with triethylamine–borane, followed by thermolysis, have led to 1,5-dipropyl-1,5-diborocane 2 and other products, but the presence of 1 could not be detected by GC–MS. Treatment of triallylborane with monobromoborane, methanolysis and subsequent thermolysis gave 1,5-dimethoxy-1,5-diborocane 3 which could be converted to 2 by treatment with propylmagnesium

    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
