General description

碘化钠是一种无机钠盐，通常在有机合成中用作碘离子的来源。通过亲核位移反应将烷基卤化物和磺酸盐转化为烷基碘化物和芳基碘化物。此外，NaI 还与氧化剂结合使用，用于有机硼烷、酚类和芳香族化合物的碘化。

Application

碘化钠可用于以下方面：      
  • NaI-AlCl3 在酮肟到苯胺的 Beckmann 重排中用作脱水剂。      
  • 以硅胶负载的氯化铈用作催化剂，以通过邻苯二胺与酮的反应合成 2,3-二氢-1H-1,5-苯二氮卓类药物。      
  • NaI-二氯二甲基硅烷催化体系用于将二芳基甲醇还原为相应的二芳基甲烷。

Features and Benefits

  • 提高效率——免除需要松散硬化粉末的时间和精力     
  • 更加安全——无需使用工具大力敲碎团块
  • 更加环保——不会粘在包装上，减少了浪费     
  • 更加经济——制备和溶剂化速度更快，提高效率并节约成本      
  • 质量保证——经过专业检测的出色品质，无抗结剂添加     
  • 灵活的用量选择——有从研究到放大级别的用量规格可供选择。
