Descripción general
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.
Aplicación
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.

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

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
