  Infrared Spectra of Alkyldiboranes. III. 1,2‐Dimethyl‐ and 1,2‐Diethyldiboranes

  摘要：

  The infrared spectra of three isotopic variants of 1,2-dimethyldiborane—(CH3B10H2)2, (CH3BH2)2, (CH3BD2)2—and of five 1,2-diethyldiboranes—(C2H5B10H2)2, (C2H5BH2)2, (C2H5BD2)2, (C2D5BH2)2, (C2D5BD2)2—are reported and frequency assignments are made. 1,2-Dialkyldiboranes are very stable with respect to decomposition, but on prolonged standing rearrange to 1,1-dialkyldiboranes. Appearance of absorptions at ca 2100 and 1550 cm—1 is the first indication of the presence of 1,1-dialkyldiborane impurity. Although not conclusive, the evidence favors existence of predominantly cis configurations.

• Dimethylindium octahydrotriborate, Me2InB3H3: synthesis, crystal structure and spectroscopic properties of a volatile indium hydride

  Reaction between trimethylindium and tetraborane(10) at room temperature yields the volatile, viscous liquid dimethylindium octahydrotriborate, the first reported example of a volatile indium hydride; spectroscopic properties of the vapour indicate a molecular structure akin to that of Me2A1B3H8 although the crystal structure implies a more ionic formulation, [Me2In]+[B3H8]–, with the coordination at each indium centre being augmented via secondary intermolecular interactions with terminal hydrogen atoms.

  三甲基铟和四硼烷（10）在室温下发生反应，生成挥发性粘稠液态八氢三硼酸二甲基铟，这是首次报道的挥发性氢化铟的实例；这种蒸气的光谱特性表明其分子结构类似于 Me2A1B3H8，但晶体结构意味着其离子型更强，即[Me2In]+[B3H8]-，每个铟中心的配位通过与末端氢原子的次级分子间相互作用而增强。

  Comparison of the mass spectra of isotopically normal and 10B-enriched trimethylboroxines makes possible the identification of the various fragments. The spectra furnish independent substantiation of the molecular weight and structure of (CH3)3B3O3—a ring with considerable aromatic character. The 10B11B isotopic abundance ratio determined from the principal-peak region is 0·251. Theoretical considerations

  同位素正常和10 B富集的三甲基环硼氧烷的质谱比较使鉴定各种片段成为可能。光谱独立地证实了（CH 3）3 B 3 O 3的分子量和结构-具有相当大的芳香特性的环。由主峰区域确定的10B11B同位素丰度比为0·251。引入了涉及分子振动的理论考虑，以显示当轻原子或基团与含重硼基团的振动引起键断裂时，同位素对碎片的影响最小，因此对计算的丰度比影响最小。
