八氟戊氧丙基甲基二氯硅烷的合成及其核磁谱归属

Synthesis of octafluoropentyoxapropylmethyldichlorosilane and determination of its NMR spectra.

在相转移催化剂存在下,由八氟戊醇与氯丙烯缩合,得到中间体八氟戊基烯丙醚;再在铂催化剂催化下与甲基二氯硅烷进行硅氢加成反应,得到了八氟戊氧丙基甲基二氯硅烷。以核磁、红外、质谱、元素分析鉴定了多氟衍生物的结构,并确定了其核磁谱峰归属。

With tetrabutylamonium bromide as phase transfer catalyst,octafluoropentyoxapropene was obtained from the condensation of octafluoropenol and allyl chloride.Furthermore,octafluoropentyoxapropene was reacted with methyldichlorosilane to give the octafluoropentyoxapropylmethyldichlorosilane monomer by hydrosilylation.The structure of fluorine containing derivatives was determined by NMR,FT-IR,MS and elemental analysis.Further more,the NMR spectra were identified in the current work.
