The reaction of LGeCl [1; L = CH{(CMe)(2,6-(i)Pr(2)C(6)H(3)N)}(2)] with 1,3-di-tert-butylimidazol-2-ylidene results in the formation of the germylene L'Ge [2; L' = CH{(C=CH(2))(CMe)(2,6-(i)Pr(2)C(6)H(3)N)(2)}]. 2 reacts with ammonia under N-H cleavage to give LGeNH(2) (3). This type of reaction can also be used to activate primary amines. 3 is characterized by microanalysis, multinuclear NMR spectroscopy, and X-ray structural analysis. The single-crystal X-ray structural analysis indicates 3 to be a monomer, and the germanium atom shows a trigonal-pyramidal environment with a stereochemically active lone pair.
LGeCl [1；L = CH{(CMe)(2,6-(异丙基)₂C₆H₃N)}(2)] 与1,3-二叔丁基咪唑-2-亚基反应生成亚锗烯L'Ge [2；L' = CH{(C=CH₂)(CMe)(2,6-(异丙基)₂C₆H₃N)(2)}]。2在N-H键断裂的情况下与氨反应生成LGeNH₂ (3)。这种类型的反应也可用于活化伯胺。3通过微量分析、多核NMR光谱和X射线结构分析进行表征。单晶X射线结构分析表明3是单体，锗原子呈现具有立体化学活性孤对电子的三角锥环境。
