General description
Lithium bis(trimethylsilyl)amide (LHMDS) is a non-nucleophilic strong base widely used in organic synthesis for deprotonation reactions and base-catalyzed reactions. It is generally soluble in most nonpolar organic solvents.
Application
Lithium bis(trimethylsilyl)amide solution (1.0 M in THF) can be used as a base:
- To catalyze polymerization reaction in the synthesis of poly(p-benzamide)s.
- In the synthesis of cyclic poly(α-peptoid)s and α-(difluoromethyl)styrene.
- In directed aldol condensations and Darzens condensation reactions; α-arylation of aryl ester derivatives and allylic amination reaction.
- For the generation of kinetic enolates than sodium hexamethyldisilazide (NaHMDS) because the enolates produced are more regiostable than those produced with NaHMDS.
Packaging
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

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
