一般說明

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.

應用

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.

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
