An N-heterocyclic carbene-disilyne complex and its reactivity toward ZnCl2.
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 = Si(i)Pr[CH(SiMe(3))(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 ZnCl(2), the disilyne-NHC-ZnCl(2) complex 3 was produced, in which the Si═Si bond adopted the cis geometry.
