摘要：

Tris(trimethylsilyl)silane adds across the double bond of a variety of mono-, di-, and trisubstituted olefins under free-radical conditions in good yields. The reaction, which proceeds via a free-radical chain mechanism, is highly regioselective (anti-Markovnikov). Addition to prochiral olefins bearing an ester group is highly stereoselective. The factors that control the stereochemistry have been discussed terms of preferred conformations of the intermediate carbon-centered radicals and are thought to be of steric origin.
