一般描述
三甲基硅基胺基锂（LHMDS）是一种非亲核强碱，广泛应用于有机合成中的脱保护反应和碱催化反应。它通常可溶于大多数非极性有机溶剂。
应用
双三甲基硅基胺基锂溶液(1.0 M，溶于THF溶液)可用作碱：
- 催化聚(对苯甲酰胺)合成中的聚合反应。
- 用于环状聚（α-类肽）和α-（二氟甲基）苯乙烯的合成。
- 用于定向醛醇缩合和Darzens缩合反应；芳基酯衍生物的α-芳基化和烯丙基胺化反应。
- 与六甲基二硅基氮烷钠（NaHMDS）相比，可用于生成动力学烯醇化物（kinetic enolate），因为生成的烯醇化物比NaHMDS生成的烯醇化物更具有区域稳定性（regiostable ）。
