摘要
以氘代苯（Ｃ６Ｄ６）及单质溴（Ｂｒ２）为原料，铁粉（Ｆｅ）及单质碘（Ｉ２）为催化剂，同时改进了常规溴苯合成中粗产物的后处理工序，最终合成出了产率达７２．５％ 、氘代率达９９．２％ 的氘代溴苯（Ｃ６Ｄ５Ｂｒ）。采用付立叶变换红外光谱仪及激光拉曼光谱仪对Ｃ６Ｄ５Ｂｒ的振动光谱特性进行了研究，此外亦采用相对重量校正因子１Ｈ－核磁共振波谱法对样品氘代率的测定进行了探讨。
A simple, efficient and novel method for the synthesis of bromobenzene d 5 from commercial benzene d 6 (99.32D%) is described. Fe and a little I 2 were used as the catalysts, and the method of crude product solution treatment was improved by solid K 2CO 3. The yield of bromobenzene d 5 was 72.5%, and the deuterium content is about 99.2% measured by 1H NMR.
