• Photolysis of aryl-substituted disilanes in the presence of dimethyl sulfoxide

  日期：1978.4

  The photolysis of aryl-substituted disilanes in the presence of dimethyl sulfoxide has been studied. The products are found to be disiloxanes, aryl-substituted silanes, dimethylsilanone [(CH3)2Si=O], and dimethyl sulfide. Possible mechanisms for these reactions are discussed.

  已经研究了在二甲亚砜存在下芳基取代的乙硅烷的光解作用。发现产物为二硅氧烷，芳基取代的硅烷，二甲基硅酮[（CH 3）2 Si = O]和二甲基硫。讨论了这些反应的可能机制。
• Reaction of dimethylsilylene with cyclooctene oxide
  作者：William F. Goure、Thomas J. Barton

  日期：1980.10

  The deoxygenation of cyclooctene oxide with both thermally and photochemically generated dimethylsilylene is described. Four mechanistic possibilities are considered; two involving initial silaoxetane formation, and two involving ylide formation. It is concluded that ylide formation must be favored. However, whether this ylide actually extrudes dimethylsilanone (Me2SiO), or simply acts as a “silanone

  描述了用热和光化学产生的二甲基甲硅烷基对环辛烯氧化物进行脱氧。考虑了四种机械可能性；两个涉及初始硅氧杂环丁烷的形成，两个涉及叶立德的形成。结论是必须形成叶立德。然而，不能从数据中确定地确定该内鎓盐实际上是挤出二甲基硅酮（Me 2 Si = O），还是仅充当“硅酮转移剂”。

  The present invention is a silylating method employing of formula (CH.sub.3)(R)(R.sup.1)SiX ; where R is an isopropyl group, R.sup.1 is a monovalent hydrocarbon group having 2 to 6 carbon atoms, and X is a chlorine atom or bromine atom. The silylating agent of the present invention provide silylation product which is much more stable than the silylation product obtained with trimethylchlorosilane, and its protective group is as stable as the silylation product obtained from t-butyldimethylchlorosilane. Moreover, the present described silylating agents are characterized by an easier desilylation than the t-butyldimethylsilyl group.

  本发明是一种使用式(CH.sub.3)(R)(R.sup.1)SiX的硅烷化方法；其中，R是异丙基基团，R.sup.1是具有2到6个碳原子的单价碳氢基团，而X是氯原子或溴原子。本发明的硅烷化试剂提供的硅烷化产物比使用三甲基氯硅烷得到的硅烷化产物稳定得多，其保护基与使用叔丁基二甲基氯硅烷得到的硅烷化产物一样稳定。此外，本发明所描述的硅烷化试剂的去硅基化比叔丁基二甲基硅基团更容易。
