di-Grignard was the key step in the preparation of the parent 1,3-disilacyclohexane. For that purpose, the preparation of methylene di-Grignard has been improved and simplified. The successful synthesis of the isomeric 1,2- and 1,4-disilacyclohexanes is also reported.
1,5-二溴-1,5-二硅戊烷与亚甲基二格里纳环的闭环反应是制备母体1,3-二硅环己烷的关键步骤。为此,已经改进和简化了亚甲基二格里雅纳的制备。还报道了成功合成1,2-和1,4-二硅环己烷异构体。
