separation of mixtures, which were prepared by chlorination followed by transformations of dodecamethylcyclohexasilane (Me2Si)6 into bifunctional decamethylcyclohexasilanes X2Si6Me10 (X = Cl, H, or OH), was carried out. As a result, mixtures of the corresponding 1,3- and 1,4-derivatives were separated to obtain structural isomers, and stereoisomers, viz., cis- and trans-1,4-dihydrocyclohexasilanes, were
混合物的异构体分离是通过氯化制备的,然后将十二甲基环己硅烷 (Me2Si)6 转化为双功能十甲基环己硅烷 X2Si6Me10(X = Cl、H 或 OH)。结果,相应的1,3-和1,4-衍生物的混合物被分离以获得结构异构体,并且立体异构体,即顺式和反式1,4-二氢环己硅烷以单独的形式分离。通过 X 射线衍射分析确定了所得双功能十甲基环己烷 X2Si6Me10(X = H 或 OH)和十甲基-7-氧六硅烷降冰片烷的分子和晶体结构。双功能环己硅烷形成中间相作为塑料晶体。确定了其存在的温度范围。
