  摘要：

  The reaction of ethynylmagnesium bromide with chloroisopropylgermanes (i-Pr4-nGeCln, n = 1-3) was used to prepare previously unknown ethynylisopropylgermanes i-Pr4-nGe(C=CH)(n) (n = 1-3). The reaction of Me(3)SiCequivalent toCMgBr with i-PrGeCl3 afforded i-Pr(Me(3)SiCequivalent toC)(3-n)GeCln(n = 1, 2). The reaction of the monochloride with BrMdCequivalent toCH gave i-Pr(HC=C)(2)GeCequivalent toCSiMe(3), while with the dichloride, i-Pr(HCequivalent toC) Ge(Cequivalent toSiMe(3))(2) formed. The latter compounds were obtained by independent synthesis from i-PrGe(Cequivalent toCH)(3), EtMgBr, and ClSiMe3. The reaction of (bromomagnesioethynyl)triisopropylgermane with Me3SiCl gave i-Pr(3)GeCequivalent toSiMe(3).
