- 概述:碘苯(Iodobenzene)也称碘代苯,是苯的一碘取代物,分子式为C6H5I,是无色有特殊气味的液体,难溶于水,可溶于氯仿、乙醚和乙醇。对光敏感,见光颜色逐渐变黄。闪点74℃。 由于C-I键键能比C-Cl和C-Br键键能低,因此碘苯的反应性比氯苯和溴苯更强。它可以与镁反应生成格氏试剂苯基碘化镁(PhMgI),后者可在有机合成中用作苯基负离子的合成子等价物。 碘苯也可作为薗头偶合反应、Heck反应和其他金属催化的偶联反应中的原料。
- 用途二:用于有机合成或用作折光率标准液。

- 方法一:由苯胺经重氮化、置换而得。将30%盐酸、苯胺加入水中,搅拌冷却至2℃,缓缓滴加亚硝酸钠溶液,控制温度不超过12℃。滴加最后一部分亚硝酸钠溶液时,用碘化钾淀粉试纸测试,呈蓝色为反应终点,得重氮化液。将碘化钾溶液分多次加入重氮化液中,此时放出氮气,放置2h,至无氮气逸出为止。冷却后,分去上层水溶液。加10%氢氧化钠溶液使反应液至pH14。进行水蒸气蒸馏,馏出液分去水层,干燥后常压分馏,收集184-188℃馏分,即为碘苯,收率77%。
