一般描述
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.
应用
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.
