炔基聚硅烷的合成研究

Research on Preparation of Alkynyl polysilane

甲基苯基二氯硅烷以Wurtz反应合成聚甲基苯基硅烷,然后与乙酰氯在三氯化铝存在下发生氯交换反应得到含氯聚硅烷,含氯聚硅烷与对三甲基硅乙炔苯基锂反应即可得到侧链含有三甲基硅乙炔基的聚硅烷。经核磁共振氢谱和红外光谱分析,证实产物为侧链含有三甲基硅乙炔基的聚硅烷。

Methylphenyl dichlorosilane to Wurtz reaction synthesis of polymethylphenyl silane,and then with acetyl chloride in the presence of aluminum chloride in the presence of chlorine exchange reaction to get chlorine polysilane,chlorine polysilane and p-trimethyl silicon acetylene Phenyl lithium reaction can be obtained side chain containing trimethylsilyl ethynyl polysilane. By NMR and IR spectroscopy,it was confirmed that the product was polysilane containing trimethylsilynyl group.
