General description
双(三甲基硅基)氨基锂 溶液(LiHMDS)通常用作有机合成中的非亲核性强布朗斯台德碱。
Application
LiHMDS 可用作以下反应的试剂：
- 去质子化和亲核二氟甲基化反应。
- 通过α-苄基甲苯磺酰基甲基异氰酸酯和N-碘琥珀酰亚胺（NIS）的加成反应合成异喹啉衍生物。
- 通过芳基氟化物与双（频哪醇合）二硼之间的钯催化的交叉偶联反应制备芳基硼酸频哪醇酯。
双(三甲基硅基)氨基锂通常用作有机合成中的非亲核性强布朗斯台德碱。它可以与氟化铯进行盐复分解反应，合成双（三甲基硅基）酰胺铯（CsHMDS）和氟化锂。

Full details of an anti-selective catalytic asymmetric nitroaldol reaction promoted by a heterobimetallic catalyst comprised of Nd(5)O(O(i)Pr)(13), an amide-based ligand, and NaHMDS (sodium hexamethyldisilazide) are described. A systematic synthesis and evaluation of amide-based ligands led to the identification of optimum
