NHC‐stabilized dichlorosilaimineArN=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 dichlorosilaiminefrom substituted chlorosilane
