N-Heterocyclic carbene stabilized dichlorosilaimine IPr·Cl2SiN(Diip) (2) has been synthesized by the reaction of dichlorosilylene IPr·SiCl2 (1) with bis(2,6-diisopropylphenyl)carbodiimide (IPr = :C[N(2,6-i-Pr2-C6H3)CH]2, Diip = 2,6-i-Pr2-C6H3). Reaction of 1 with terphenyl azides also affords dichlorosilaimines IPr·Cl2SiN(2,6-Diip2-C6H3) (3) and IPr·Cl2SiN(2,6-Triip2-C6H3) (4) (Triip = 2,4,6-i-Pr3-C6H2). Compounds 24 are stable under an inert atmosphere and were characterized by elemental analysis and NMR spectroscopic studies. The molecular structures of 24 were determined by single-crystal X-ray analysis.
