β-(乙酰氧基)乙基硅化合物的合成及其性质

Syntheses and Properties of β- (Acetoxyl)ethylsilanes

报道了采用氯铂酸为催化剂,使醋酸乙烯酯发生硅氢化反应,合成了一系列的β-(乙酰氧基)乙基硅化合物,其中有21个是新的;在室温下测定了它们释放乙烯的速度;透过元素分析、质谱、红外光谱和核磁共振谱等方法,鉴定了它们的结构。

In the presence of chloroplatinic acid,a series of β-(acetoxyl)ethylsilanes were synthesized by hydrosilylation of vinylacetate. Twenty-one compounds of the type CH3CO2CH2CH2SiR3 thus synthesized were new. The rates of ethylene released of these compounds have been determined at room temperature. Their structures were characterized by elemental,mass,infrared and nuclear magnetic res-onance spectra analysis.
