The reaction of the diaminosilylene :Si(tBuNCH2CH2NtBu) (5) with the diaminogermylene :Ge(tBuNCH2CH2NtBu) is thought to proceed via a germasilene silylgermylene rearrangement and dimerisation to furnish the (Z)−1,2-diamino-1,2-disilyldigermene (Z)-9. The X-ray structure analysis of (Z)-9 reveals a long GeGe bond length of 245 pm and a large trans-bent angle of 42°. Air-oxidation of (Z)-9 takes place
二氨基亚甲硅基:Si(tBuNCH 2 CH 2 NtBu)(5)与二氨基亚锗基:Ge(tBuNCH 2 CH 2 NtBu)的反应被认为是通过a硅甲硅烷基亚锗烷基重排和二聚反应进行的,以提供(Z)−1,2 -二氨基-1,2-二甲硅烷基二甘油(Z)-9。的X射线结构分析(Z) - 9揭示了245微米的长GEGE键长和大的反式的42°角-bent。(Z)-9的空气氧化发生并保留了锗原子上的构型,以提供相应的取代的(Z)-2,4-二茂铁-1,3-二氧杂环丁烷(Z)-10。治疗5用亚锡基:Sn [N(SiMe 3)2)2的最终产物,得到氢化二甲硅烷基锡烷12。(Z)-10和12的结构也通过X射线晶体学确定。
