Tris(trimethylsilyl)silyl Radical Induced Bicyclization of 1,6-Dienes and 1,6-Enynes Providing 3,3-Bis(trimethylsilyl)-3-silabicyclo[3.3.0]octanes and 3-Silabicyclo[3.3.0]oct-1-enes

Treatment of 1,6-dienes with tris(trimethylsilyl)silane in the presence of Et3B or α,α′-azobis(isobutyronitrile) afforded 3,3-bis(trimethylsilyl)-3-silabicyclo[3.3.0]octanes in addition to monocyclized cyclopentanes. Bicyclization of 1,6-enynes provided the corresponding 3-silabicyclo[3.3.0]oct-1-enes.
在 Et3B 或 α,α′-偶氮二异丁腈存在下,用三(三甲基硅基)硅烷处理 1,6- 二烯,除了得到单环戊烷外,还得到了 3,3-双(三甲基硅基)-3-硅杂双环[3.3.0]辛烷。1,6-烯炔的双环化提供了相应的 3-硅杂双环[3.3.0]辛-1-烯。
