Abstract

A 1,4-diamino-2,3-disila-1,3-butadiene derivative of composition (Me ₂-cAAC)₂(Si₂Cl₂) (Me ₂-cAAC =:C(CMe₂)₂(CH₂)N-2,6-iPr ₂C₆H₃) was synthesized by reduction of the Me₂-cAAC:SiCl₄ adduct with KC₈. This compound is stable at 0 C for 3 months in an inert atmosphere. Theoretical studies reveal that the silicon atoms exhibit pyramidal coordination, where the Cl-Si-Si-Cl dihedral angle is twisted by 43.3 (calcd 45.9). The two silicon-carbon bonds are intermediates between single and double Si-C bonds due to twisting of the C-Si-Si-C dihedral angle (163.6).
