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-silylketenes upon prolonged storage.
Lewis Acid-Activated Reactions of Silyl Ketenes for the Preparation of α-Silyl Carbonyl Compounds

Silyl-substituted ketenes are attractive molecular building blocks due to their stability and ease of storage, as opposed to unstable alkyl and aryl ketenes. To better understand the reactivity of silyl ketenes and, in turn, their use in the preparation o

Cycloadditions, III. - Reactions of Ynamines with Silylketenes
Himbert, Gerhard,Henn, Lothar
, p. 1358 - 1366 (2007/10/02)
The ynamines 1a-e react with the silyl aldoketenes 2a and b in a normal way under cycloaddition to give the allenecarboxamides 6 and in one case a cyclobutenone derivative.The presence of the silyl group in the adducts gives rise to 1,3-migrations of
