有机硅聚合物过渡金属络合催化剂的合成与活性——Ⅰ.γ-卤苯基丙基三氯硅烷和γ-卤苯基丙基烷基二氯硅烷及其与正硅酸乙酯共聚物的合成 THE SYNTHESIS AND ACTIVITY OF SILICONE SUPPORTED TRANSITION METAL COMPLEX CATALYSTS Ⅰ. The Synthesis of γ-Halophenylpropyltrichlorosilane and γ-Halophenylpropylalkyldichlorosilane Monomers and their Tetraethoxysilane CopolymerS. 陈远荫 first-author 刘基万 林颐庚 倪继金 游江 肖超勃 王玉华 三氯氢硅或烷基二氯硅烷在氯铂酸催化下与m-或p-卤代烯丙苯加成,得到十一种新型γ-卤苯基丙基三氯硅烷和γ-卤苯基丙基烷基二氯硅烷。产率一般为60～70%,个别达到80%。元素分析、红外光谱和氢硅化反应的定位规则表明它们具有预期的结构。这些单体与正硅酸乙酯共水解和聚合,得到十种新型的含有γ-卤苯基的共聚物。 γ-Halophenylpropyltrichlorosilane and γ-halophenylpropylalkyldichlorosilane monomers were prepared from corresponding halogen substituted allylbenzenes by hydrosilylation with trichlorosilane or alkyldichlorosilanes in the presence of chloroplatinic acid as a catalyst. The yields were 54—70% in general, but in a few instances nearly 80% could be achieived. Data of elemental analy sis and infrared spectra, as well as the orientation rule in hydrosilylation showed that they would have expected γ-trichlorosilylpropyl or γ-alkyldichlorosilylpropyl structures. These monomers were subjected to cohydrolysis with ethyl orthosilicate and subsequent polymerization to give copolymers. 1981-04-01 2021-04-01 4
