一般說明

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。

應用

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 )。

High-density live cell array serves as a valuable tool for the development of high-throughput immunophenotyping systems and cell-based biosensors. In this paper, we have, for the first time, demonstrated a simple fabrication process to form the hexamethyldisilazane (HMDS) and poly(ethylene

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

Common dehydration methods of cells on biomaterials for scanning electron microscopy (SEM) include air drying, hexamethyldisilazane (HMDS) or tetramethysilane (TMS) treatment and critical point drying (CPD). On the other side, freeze-drying has been widely employed in dehydrating biological samples and
