The thermal decomposition of hexamethylsilirane in the presence of selected disubstituted acetylenes (Me3SiCCSiMe3), Me2HSiCCSiMe2H, Me3SiCCCH3, Me3SiCCCMe3, Me3CCCCH3) resulted in Me2Si addition to the CC bonds to give the respective silacyclopropenes. These are thermally stable but are extremely reactive toward atmospheric oxygen and moisture and react readily with methanol and ethanol at room

Hexamethylsilirane has been prepared by the action of magnesium on dimethyl-bis(α-bromoisopropyl)silane in tetrahydrofuran (THF) solution. It was found to be highly reactive toward atmospheric oxygen and moisture and to decompose when heated in solution at 60–75°C. Its decomposition results in the extrusion of dimethylsilylene which may add to the tetramethylethylene produced in the decomposition to
六甲基甲硅烷基烷是通过镁在四氢呋喃(THF)溶液中的二甲基双(α-溴异丙基)硅烷作用下制备的。发现它对大气中的氧气和湿气具有很高的反应性,并且在60–75°C的溶液中加热时会分解。它的分解导致二甲基甲硅烷基的挤出,该二甲基甲硅烷基可能会添加到分解过程中产生的四甲基乙烯中,从而再生出硅烷,插入到硅烷的反应性SiC 2环中以生成八甲基-1,2-二硅环丁烷或低聚生成(Me 2 Si )n油。

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 (Me2SiO), 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”。
