Preparation and structural characterization of trimethylsilyl-substituted germylzinc halides, (Me3Si)3GeZnX (X=Cl, Br, and I) and silylzinc chloride, R(Me3Si)2SiZnCl (R=SiMe3 and Ph)
摘要:
The trimethylsilyl-substituted germylzine halides, (Me3Si)(3)GeZnX (X = Cl, Br, and 1), and silylzinc chlorides, R(Me3Si)(2)SiZnCl (R = SiMe3, Ph), have been prepared and their molecular structures have been full determined by spectroscopic and single-crystal Xray diffraction methods. The germylzinc halides and silylzinc chlorides have dimeric structures consisting of two mu-halogen atoms. The reactivity of germylzinc chloride with substrates is also examined.
