  • 实验室制备碘甲烷:在甲醇与红磷的混合物中加入碘时,会发生放热反应而生成碘甲烷:5 CH3OH + P + 2.5 I2 → 5 CH3I + H3PO4 + H2O 反应中生成了三碘化磷中间体,起到了与甲醇发生碘化反应的作用。 碘甲烷也可由硫酸二甲酯与碘化钾在碳酸钙存在下反应制得:(CH3O)2SO2 + KI → K2SO4 + 2 CH3I 先将反应产物蒸馏,然后用Na2S2O3、水和Na2CO3溶液洗涤,便可得到纯净的碘甲烷。

  • 甲基化反应:碘甲烷与碳酸二甲酯、硫酸二甲酯、三氟甲磺酸甲酯是常见的甲基化试剂 根据软硬酸碱理论,碘是“软”的阴离子,因而碘甲烷所参与的甲基化反应也应在两位亲核试剂较“软”的一段发生。比如,在与硫氰酸根离子反应时,S更软,因而从S原子进攻的可能性较从N原子进攻的可能性大,产物主要是硫氰酸甲酯(CH3SCN)而非CH3NCS。而且,碘甲烷与1,3-二羰基化合物生成的烯醇盐之间发生的反应也可用以上理论来解释。相对于碳原子,氧原子较硬,碘甲烷参与的反应也几乎都生成C-甲基化的产物。 碘甲烷甲基化具有以下一些缺点: 它相对分子质量较大,一摩尔MeI的质量几乎等于三摩尔CH3Cl的质量; 碘化合物较氯化物和溴化物仍显得比较昂贵,因而在工业上更加便宜的硫酸二甲酯仍有不少应用,尽管它的毒性比碘甲烷要高出很多; 碘离子离去基团可能会造成副反应; 碘甲烷的毒性比相应的氯化合物和溴化合物要大,对生产工人很不利。 因此在选择甲基化试剂时,通常要均衡考虑价格、来源、毒性、化学选择性及反应容易程度等诸多因素。
  • 用途一:主要用作甲基化试剂,在医药工业中用于碘甲基蛋氨酸(维生素U)、镇痛药、解毒药磷酸系药物的生产
