Application
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.
General description
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.

Using the pyrolysis-gas chromatography-mass spectrometry and off-line pyrolysis/silylation methods for lignites from three Miocene brown coal basins of Poland resulted in the characterization of many organic compounds, including dominant cellulose degradation products such as levoglucosan, 1,6-anhydro-beta-D-glucofuranose, and 1,4:3,6-dianhydroglucopyranose. Levoglucosan is

The objectives of this study were to assess demineralized dentin porosity and quantify the different porous features distribution within the material using mercury intrusion porosimetry (MIP) technique. We compared hexamethyldisilazane (HMDS) drying and lyophilization (LYO) (freeze-drying) in sample preparation. Fifty-six
