Application
NaHMDS可作为碱用于:
- 通过1,4-消除反应从N-羰基-1-氨基-4-甲氧基-2-烯烃中合成 N-羰基-1-氨基-1,3-二烯衍生物。
- 使烷基或芳基酮去除质子化,以通过羟基化反应生成烯酸衍生物。
- 在双金属非均相催化剂催化下,在硝基烷烃与醛之间通过硝基醇反应对映选择性合成1,2-氨基醇。
General description
双(三甲基硅基)氨基钠溶液(NaHMDS)作为强碱广泛应用于有机合成中的脱质子反应和碱催化反应。它还参与烯醇、威提格试剂和卡宾的生成。
Packaging
推荐将25毫升安全/密封™瓶作为一次性使用的瓶子。重复穿刺可能会导致产品性能下降。
