  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.

  Silylation of silylketenes RSiCH=C=O 1 (a, R=Et-3; b, R=(BuMe2)-Bu-t; c, :R=Pr-i(3)) with trimethylsilyltriflate in the presence of triethylamine was studied. Mixtures of the corresponding 1-trimethylsiloxy-2-silylethynes RSiC=COSiMe3 2 and trimethylsilyl(silyl)ketenes RSi(Me3Si)C=C=O 3 in the case of la and Ib were obtained. By this reaction only 2c was prepared from Ic. Heating of mixtures of 2a, 3a and 2b, 3b at 100-110 degrees C affords pure ketenes 3a and 3b respectively; heating of 2c under the same conditions takes place practically without rearrangement.
