Silylation and germylation of trialkylsilyl(germyl)ethoxyacetylenes containing bulky substituents at the silicon or germanium atom

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.

(Aminoethynyl) Metallations, 18. - Reactions of (Stannylethynyl) and (Silylethynyl) Ethers with Acylketenes

(Stannylethynyl) ethers 1 react with tert-butylcyanoketene (2) to give the (stannyloxyvinyl)yne ethers 4.Reaction with an educt ratio of 1:2 furnishes via the primarily formed zwitterion 3 (=1,4-dipole) the dioxine derivatives 6 which lose their stannyl g

Cycloadditions, III. - Reactions of Ynamines with Silylketenes

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
