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 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.
