以季戊四醇为原料合成了一种新型树状大分子核——醚-四硅烷,可用于树状大分子构筑.通过季戊四醇(1)与溴丙烯的醚化反应得到四烯丙基醚2,然后在Pt催化作用下,2与硅氯仿通过硅氢化反应生成醚-四(三氯硅烷)3(可直接与多种官能团反应生成树状大分子),3经过LiAlH4还原后得到目标产物醚-四硅烷4.通过IR, 1H NMR, 13C NMR对中间体和目标产物的结构进行了表征,并对产物的结构进行了讨论和确认.

A novel ethereal tetrasilane based on pentaerythritol was synthesized. Etherification of pentaerythritol (1) with allyl bromide giving tetraallyl ether 2, followed by Pt-catdlyzed hydrosilication with silicochloroform generated tetratrichlorosilane 3 (which could directly react with some functional groups to form dendrimers) and subsequent reduction of 3 with LiAlH4 provided tetrasilane 4, which could be used in hydrosilication with unsaturated olifens and their derivatives to form carbosilane dendrimers.

Key words: pentaerythritol, ethereal tetrasilane, hydrosilication, dendrimer
