摘要
利用四烃基锡化合物与浓盐酸直接混合加热反应,合成了3种混合二烃基二氯化锡(Ⅳ);通过IR、1HNMR和3CNMR的测定,对产物的结构进行了表征,探讨了反应温度、时间及浓盐酸的用量对反应产率的影响,当四烃基锡与浓盐酸的物质的量比为1∶12,在92℃下反应9min,混合二烃基二氯化锡的产率>70%。与其他方法相比较,该方法具有操作简单、对环境污染小、产率较高等特点,符合绿色化学的要求。
Three mixed dialkly tin dichlorides have been synthesized by the reaction of tetralkyl tin with concentrated hydrochloric acid. Their structures were characterized by ^1HNMR, ^13CNMR,and IR spectroscopy. The effects of temperature, molar ratio of reactants, and reaction time on product yield were investigated. The experimental results showed that the method had the advantage of simple operation, quick reaction, reduced pollution, and high yield to meet the demands Of green chemistry compared with other methods.
