Silicon(II) bis(trimethylsilyl)amide (LSiN(SiMe(3))(2), L= PhC(NtBu)(2)) (2) has been synthesized by the reaction of LSiHCl(2) with KN(SiMe(3))(2) in 1:2 molar ratio in high yield where 1 equiv of the latter functions as a dehydrochlorinating agent. 2 exhibits a high stability up to 154 °C and can be handled in open air for a short period of time without any appreciable decomposition. An amazing five-membered cyclic silene (3) results from the cleavage of one Si-Me bond of 2 with an adamantyl phosphaalkyne. 3 is the first example of a heavy cyclopentene derivative which consists of four different elements, C, N, Si, and P. Both compounds are characterized by multinuclear NMR spectroscopy, EI-mass spectrometry, and single crystal X-ray diffraction studies.
二(三甲基硅基)硅酰胺（LSiN(SiMe(3))(2)，L= PhC(NtBu)(2)）（2）通过 LSiHCl(2)与 KN(SiMe(3))(2)以 1:2 的摩尔比反应合成，后者的 1 当量用作脱氯化氢试剂。2 在高达 154°C 的温度下表现出高稳定性，并且可以在短时间内在开放空气中处理而没有任何明显的分解。与金刚烷膦炔反应，2 的一个 Si-Me 键断裂，生成令人惊讶的五元环状硅烯（3）。3 是第一个由 C、N、Si 和 P 四种不同元素组成的重环戊烯衍生物。这两种化合物都通过多核 NMR 光谱、EI-质谱和单晶 X 射线衍射研究进行了表征。
