  摘要：

  Silylation of silyl- and germylketenes with trialkylsilyl triflates was studied. Either the corresponding bis-organoelement-substituted ketenes or mixtures of these compounds with isomeric (silyloxy)silylacetylenes were formed depending on the size of the substituents at the silicon or germanium atom (both in ketenes and triflates) and on the nature of the heteroelement. The resulting (silyloxy)silylacetylenes were isomerized into the corresponding bis-sitylketenes upon prolonged storage.

  Disilylketenes undergo selective mono-desilylation upon treatment of t-BuOK in the presence of HMPA. The resulting silylethynolates are convertible to other disilylketenes in good yields. The intermediary silylethynolate was analyzed by NMR and IR spectroscopy.

  在 HMPA 的存在下，二硅烷基烯烃经 t-BuOK 处理后会发生选择性单脱硅反应。生成的水杨硫酸盐可以很好地转化为其他二硅烷基烯烃。通过核磁共振和红外光谱分析了中间体水飞蓟醇。

  Silylation and germylation of trialkylsilyl(germyl)ethoxyacetylenes containing bulky substituents at the silicon or germanium atom were performed. In all cases, the corresponding bis-organoelement-containing ketenes were obtained as the only reaction products. No intermediate isomeric ynol ethers were detected by spectroscopy.
