四苯基苯、吡啶基三苯基苯环四硅氧烷的合成

摘要

将四苯基环戊二烯酮或吡啶基三苯基环戊二烯酮分别与七甲基乙烯基环四硅氧烷进行Diels－Alder反应，生成了七甲基四苯基苯环四硅氧烷和七甲基吡啶基三苯基苯环四硅氧烷，并用元素分析、IR、Raman和1H NMR对产物进行了表征。%Heptamethyltetraphenylphenylcyclotetrasiloxane and heptamethylpyridyltriphenylp-henylcyclotetrasiloxane were synthesized by Diels-Alder reaction of tetraphenylcyclopentadienone or pyridyl-triphenylcyclopentadienone with Heptamethylvinylcyclotetrasiloxane,respectively.They were characterized by means of elemental analysis,IR,Raman and 1H NMR.
