for the anti–anti (aa) conformer. The dipole moment for the 74 Ge containing species has been measured, giving a total dipole moment of 0.881 (26) D. In addition, the vibrational spectrum of n -butylgermane is described. Modestly complete assignments are made for the aa conformer. The relative stabilities of the five conformers are calculated, and the anti–anti (aa) conformer is found to be the most
摘要 正丁基锗烷 CH 3 CH 2 CH 2 CH 2 GeH 3 的 FT 微波光谱在 4000 到 18,000 MHz 范围内进行了研究,并观察了所有五种天然锗同位素的微波光谱,用于抗抗(aa) 符合者。已经测量了 74 Ge 包含物种的偶极矩,给出了 0.881 (26) D 的总偶极矩。此外,还描述了正丁基锗烷的振动谱。对 aa 构象者进行了适度完整的分配。计算了五种构象异构体的相对稳定性,在所有计算中发现抗反 (aa) 构象异构体是最稳定的。退火晶体的红外光谱和拉曼光谱证实了这一结论。所有构象异构体的偶极矩计算为近似相等且小于 1 D,

[Pt(NHC′)(NHC)][BArF] (where NHC is a N-heterocyclic carbene ligand and NHC′ its metalated form) react with tertiary hydrogermanes HGeR3 at room temperature to generate the 14-electron platinum(II) germyl derivatives [Pt(GeR3)(NHC)2][BArF]. Low-temperature NMR studies allowed us to detect and characterize spectroscopically some of the σ-GeH intermediates [Pt(η2-HGeR3)(NHC′)(NHC)][BArF] that evolve into
The relative reactivities of Zn, Al, and Sm carbenoids in the chemoselective carbene insertion reaction of heaviergroup14hydrides were studied. By variation of the reaction protocols using Sm carbenoids, insertion reaction can favour the Ge-H bonds to give Ge-alkylated derivatives in good to high yield.
