  A Series of Isopropyl-Substituted Oligogermanes Prⁱ₃Ge(GePh₂)_nGePrⁱ₃ (n = 0–3) Featuring a Luminescent and Dichroic Pentagermane Prⁱ₃Ge(GePh₂)₃GePrⁱ₃

  摘要：

  The series of oligogermanes (Pr3Ge)-Ge-i(GePh2)(n)GePr3i (n = 0, 2; n = 1, 3; n = 2, 4; n = 3, 5) were prepared by the hydrogermolysis reaction. All four species were characterized by NMR (H-1 and C-13) and UV/visible spectroscopy as well by cyclic voltammetry and differential pulse voltammetry. The oligogermanes exhibited a successive red shift in their absorbance maxima as the length of the Ge-Ge chain was increased, and these molecules also became easier to oxidize as the chain length was increased. The X-ray crystal structures of 4 and 5 as well as the trigermane HPh2GeGePh2GePh2H (6) were determined. The pentagermane 5 was shown to be dichroic in the solid state due to the packing of the individual molecules in a columnar fashion in the crystal. Pentagermane 5 is also luminescent in solution, exhibiting an emission maximum at 380 nm. The physical properties of 5, like the hexagermane (Pr3Ge)-Ge-i(GePh)(4)GePr3i, mimic the properties of the larger polygermane systems.

• Application of Free Radical Substitution Reaction into Interconversion of 1-Alkenylsulfides, 1-Alkenylgermanes, and 1-Alkenylstannanes

  Treatment of 1-alkenylsulfides or 1-alkenylstannanes with Ph3GeH in the presence of Et3B provides 1-alkenyltriphenylgermanes in good yields. 1-Alkenylstannanes are converted into 1-alkenylsulfides easily with PhSH–Et3B, whereas 1-alkenyltriphenylgermanes are recovered unchanged upon treatment with Ph3SnH–Et3B or PhSH–Et3B.

  在有 Et3B 存在的情况下，用 Ph3GeH 处理 1-烯基硫化物或 1-烯基锡烷，可以得到产率很高的 1-烯基三苯基锗。1- 烷基锡烷在 PhSH-Et3B 的作用下很容易转化为 1- 烷基硫化物，而 1- 烷基三苯基锗在 Ph3SnH-Et3B 或 PhSH-Et3B 的作用下可以原封不动地回收。

  The formation of amide bonds is an important process since this linkage is an essential component in proteins, pharmaceuticals, and other medicinally and biologically significant molecules. Recently, it was demonstrated that germylamines R₃GeNR’₂ were useful reagents for the conversion of acid fluorides to amides. This transformation occurs readily at room temperature and has a low activation energy. In the present study, the versatility of this amidation reaction with aryl acid fluorides is investigated. A series of thirteen acid fluorides with various substituents on the aromatic ring were reacted with the germylamine Ph₃GeNMe₂ and twelve of these were converted to the corresponding amides in high yields, the exception being 1,4‐benzenedicarbonyl difluoride. The germylamines Buⁿ₃GeNMe₂ and Prⁱ₃GeNMe₂ also could be used for this interconversion, and both of these species successfully converted 1,4‐benzenedicarbonyl difluoride to the corresponding amide. In addition, the crystal structure of Ph₃GeNMe₂ is reported. This represents one of only three crystallographically characterized germylamines. The synthesis and ¹⁹F NMR characterization of three fluorogermanes R₃GeF (R=Buⁿ, Prⁱ, and Mes) are also reported herein.

  摘要酰胺键的形成是一个重要的过程，因为这种连接是蛋白质、药物和其他具有药物和生物意义的分子的重要组成部分。最近的研究表明，胚芽胺 R3GeNR'2 是将酸性氟化物转化为酰胺的有用试剂。这种转化在室温下很容易发生，而且活化能很低。本研究探讨了这种与芳基酸性氟化物的酰胺化反应的多功能性。一系列在芳香环上具有不同取代基的 13 种酸氟化物与胚芽胺 Ph3GeNMe2 发生了反应，其中 12 种以高产率转化为相应的酰胺，1,4-苯二羰基二氟化物除外。胚芽胺 Bun3GeNMe2 和 Pri3GeNMe2 也可用于这种相互转化，它们都成功地将 1,4-苯二羰基二氟化物转化为相应的酰胺。此外，还报告了 Ph3GeNMe2 的晶体结构。这是仅有的三种具有晶体学特征的胚芽胺之一。本文还报道了三种氟锗（R3GeF，R=Bun、Pri 和 Mes）的合成和 19F NMR 表征。
