  在过度拥挤的二氯甲基硅烷与芳基锂的反应中通过分子内环化意外形成二氢苯并硅氧烷衍生物

  摘要：

  The reaction of overcrowded aryldichloromethylsilane 1 bearing a 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl (Bbt) group with an excess amount of XylLi or MesLi (Xyl = 2,6-xylyl, Mes = mesityl) unexpectedly afforded the corresponding dihydrobenzosilole derivative 2 together with silyl-migrated olefin 3. The generation of 2 in this reaction is most likely interpreted in terms of intermediacy of 1,2-dihydro-2-chlorosilene 4.
