Reaction of the N-heterocyclic carbene (NHC)-stabilized silylene ArN(SiMe3)Si(IiPr)Cl (1, Ar = 2,6-iPr2C6H3, IiPr = 1,3-diisopropyl-4,5-dimethyl-imidazol-2-ylidene) with SiCl4 resulted in the formation of three different products NHC-stabilized dichlorosilaimine ArNSi(IiPr)Cl2 (2), aminotrichlorosilane ArN(SiMe3)SiCl3 (3) and a silaimine dimer (ArNSiCl2)2 (4) under different conditions. The products
N杂环卡宾(NHC)稳定的亚甲硅烷基ArN(SiMe 3)Si(IiPr)Cl(1,Ar = 2,6-iPr 2 C 6 H 3,IiPr = 1,3-二异丙基-4,5的反应-二甲基-咪唑-2-亚基)与SiCl 4形成三种不同的产物,NHC稳定的二氯硅亚胺ArN Si(IiPr)Cl 2(2),氨基三氯硅烷ArN (SiMe 3)SiCl 3(3)和硅亚胺二聚体(ArNSiCl 2)2(4)在不同条件下。可以通过反应条件控制产物。化合物2通过亚甲硅烷基与SiCl 4的反应,是NHC负载较小的硅亚胺的第一个例子。
