The three-membered silacyclic ring compounds LSi[N(2)(Ph)(2)]tBu (1), LSi[HCN(Ph)(2)]tBu (2) and LSi[C(2)(Ph)(2)]tBu (3) were obtained by the treatment of base stabilized monoalkylsilylenes LSitBu (L = PhC(NtBu)(2)) with PhN=NPh, PhN=CHPh and PhC≡CPh. The reaction of PhN=NPh and PhC≡CPh with LSitBu shows a different reactivity pattern with base stabilized monochlorosilylene LSiCl. The arrangement of the three-membered ring (SiNN) in 1 is the first structurally isolated example of a siladiaziridine compound.
三员环硅杂环化合物 LSi[N(2)(Ph)(2)]tBu(1)、LSi[HCN(Ph)(2)]tBu(2)和 LSi[C(2)(Ph)(2)]tBu(3)是通过碱稳定的单烷基硅烯 LSitBu(L = PhC(NtBu)(2))与 PhN=NPh、PhN=CHPh 和 PhC≡CPh 的反应得到的。PhN=NPh 和 PhC≡CPh 与 LSitBu 的反应表现出与碱稳定的单氯代硅烯 LSiCl 不同的反应活性模式。在 1 中,三员环(SiNN)的排列是第一个结构上分离的硅氮丙啶化合物实例。
