NHC‐stabilized dichlorosilaimine ArN=Si(IiPr)Cl2 (2) (Ar = 2,6‐iPr2C6H3, IiPr = 1,3‐diisopropyl‐4,5‐dimethylimidazol‐2‐ylidene) and disilane LSiHCl‐SiCl2L (L=ArNSiMe3) (3) could be synthesized from the reaction of aminodichlorosilane ArN(SiMe3)SiHCl2 (1) with IiPr under different conditions. This represents the first route to the generation of donor‐stabilized dichlorosilaimine from substituted chlorosilane
NHC-稳定dichlorosilaimine ARN =硅(I我PR)氯2(2)(Ar为2,6-我镨2 ç 6 ħ 3,我我PR = 1,3-二异丙基-4,5-二甲基咪唑-2-亚氨基)和乙硅烷LSiHCl‐SiCl 2 L(L = ArNSiMe 3)(3)可以通过氨基二氯硅烷ArN(SiMe 3)SiHCl 2(1)与I iPr在不同条件下。这代表了在NHC存在下,通过脱氢甲硅烷基化反应,由取代的氯硅烷生成供体稳定的二氯硅亚胺的第一条途径。
