摘要
The reaction of disilyne 1 with 1,3,4,5-tetramethylimidazol-2-ylidene (an N-heterocyclic carbene, NHC) produced the disilyne-NHC complex 2, RLSi=SiR: (R = (SiPr)-Pr-i[CH(SiMe3)(2)](2), L = NHC), with a trans geometry of the Si-Si moiety and lone-pair electrons residing on one of the double-bonded Si atoms. Upon complexation of 2 with ZnCl2, the disilyne-NHC-ZnCl2 complex 3 was produced, in which the Si-Si bond adopted the cis geometry.
