| 摘 要： | 本文报导了与硅原子直接相连的有机基团(R)对杂氮硅三环成环速率的影响。利用气相色谱检测成环反应的产物之一——乙醇的生成速率和数量,并同与硅相连的R基团对成环反应速率的影响作比较。实验结果表明五种杂氮硅三环成环速度顺序为Cl_2CH—>ClCH_2—>ClCH_2CH_2CH_2—>CH_2=CH—>CH_3—,这与理论推断相符。

| Abstract: | Influence of the substituents on silicon atom on the cyclization reaction of silatraneswas investigated.It wasfound that the electro-withdrawing group facilitated the reaction but theelectro-releasing group does not advantage the reaction. The amount of alcohol formed during the cyclization was determined by gas chromatography.A plot of percentage conversion against reaction time was made.In DMF we have successfullydetermined the rates of cyclization in the following order; C1_2CH->C1CH_2->C1CH_2CH_2CH_2->CH_2=CH->CH_3- These results were consistent with the theoretical assumption.Higher rates of reaction werealso observed at higher temperature and with organyltrimethoxysilane. |
