Descrição geral
Lithium bis(trimethylsilyl)amide is commonly used in organic synthesis as a non-nucleophilic strong Bronsted base. It is soluble in most nonpolar solvents such as aromatic hydrocarbons, hexanes, and THF.
Aplicação
Lithium bis(trimethylsilyl)amide can be used as a reagent:
- In the deprotonation and nucleophilic difluoromethylation reactions.
- 3-methoxy substituted dihydropyrrole derivatives by reacting with aldehydes and lithiated methoxyallene via in situ formations of N-trimethylsilylated imines.
- In Darzens condensation and directed aldol condensation reactions.
- To synthesize poly(N-octyl-p-benzamide)s by chain-growth polycondensation of 4-octylaminobenzoic acid methyl ester.

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

A silica microsphere suspension and a silica sol are employed in a two-step dipping process for the preparation of a superhydrophobic surface. It's not only a facile way to achieve the lotus effect, but can also create a multi-functional surface

Trimethylsilylation of cellulose in different 1,3-dialkylimidazolium ionic liquids (IL) with hexamethyldisilazane (HMDS) as a silylating agent was investigated. Trimethylsilyl (TMSi) cellulose with a degree of substitution (DS) greater than 1 is insoluble in the IL. The maximum DS obtained depends
