  Substituent Effects in Linear Organogermanium Catenates

  摘要：

  The trigermanes EtOCH2CH2Ge(R-2)Ge(Ph-2)Ge(R-2)CH2CH2OEt (R = Et, Bu, Ph) and Ph3GeGe(Bu-2)Ge(Ph-2)CH2CH2OEt as well as the two tetragermanes Ph3GeGe(Bu-2)Ge(Ph-2)Ge(R-2))CH2CHOEt (R = Et, Bu) have been prepared and characterized. The absorption and electrochemical attributes of these species, along with the butylated oligogermane series Ph3Ge(GeBu2)(n)CH2CH2OEt (n = 1-3) and the digermanes Ph3GeGeR3 (R = Et, Bu, Pr-i, Ph), have been investigated using UV/visible spectroscopy and cyclic voltammetry. In general, the position of the absorption maximum shifts to lower energy and the oxidation potential decreases with increasing chain length. Variation of the organic substituents at germanium was also found to have a measurable effect on these spectral and electrochemical features. The experimental results were correlated with the energies of the HOMO and LUMO in these molecules, which were determined by density functional theory (DFT) calculations.

  the formation of germanium−germanium bonds. The Ge−Ge bond forming reaction involves a germanium amide and a germanium hydride and requires the use of acetonitrile as the solvent. A key factor in the formation of the Ge−Ge bond involves reaction of the germanium amide R3GeNMe2 with acetonitrile solvent to furnish an α-germylated nitrile R3GeCH2CN which contains a labile Ge−C bond. This species undergoes

  已经证明加氢热分解反应可用于形成锗锗键。Ge-Ge键形成反应涉及酰胺锗和氢化锗，需要使用乙腈作为溶剂。Ge-Ge键形成的关键因素涉及锗酰胺R 3 GeNMe 2与乙腈溶剂的反应，以提供包含不稳定的Ge-C键的α-锗化丁腈R 3 GeCH 2 CN。该物质随后与氢化锗R 3 GeH发生反应以形成Ge-Ge键。使用这种方法，Digermanes Bu n 3 GeGePh 3和Et 3 GeGePh 3已经获得了它们的X射线晶体结构，并且已经确定了它们的X射线晶体结构。还实现了逐步合成寡聚体链的三个合成子R 2 Ge（NMe 2）CH 2 CH 2 OEt（R = Et，Bu，Ph）的制备。这些合成子与CH 3 CN中的Ph 3 GeH反应，得到相应的二锗烷，在R = Et和Bu的情况下，它们随后与DIBAL-H反应生成二锗烷氢化物。然后，使乙基和正丁基二锗烷氢化物与另外等价的适当合成子反应，
