Abstract
1. Two methods were developed for the preparation of secondaryγ-silyl acetylenic thiols, a new class of organosilicon compounds. One method is based on the reaction ofγ-silyl acetylenic chlorides with sodium hydrosulfide, and the other on reaction between silyl acetylenic chlorides and sodium thiocyanate with subsequent reaction of the silyl acetylenic thiocyanates with a Grignard reagent. 2. Secondaryγ-silyl acetylenic thiols readily add to vinyl ethers, both by ionic and by radical mechanisms. 3. Symmetrical silyl acetylenic sulfides were oxidized with hydrogen peroxide to the corresponding sulfones. 4. Fourteen previously undescribed organosilicon compounds were prepared.
