Conclusions
-
1.
The reaction of the sodium derivative of trimethylsilylacetylene with γ-, σ-, and ɛ-silicon-containing ketones was studied. A method was found of preparing tertiary acetylenic alcohols with two silicon atoms per molecule.
-
2.
The alcohols prepared were dehydrated to give the corresponding alkenes containing two silicon atoms. Hydration of the latter compounds is accompanied by cleavage of the silicon-acetylenic Si-C bond, which results in the formation of unsaturated organosilicon ketones.
