General description
Tetrabutylammonium fluoride trihydrate is a mild base used in reactions like aldol-type condensation reactions, Michael-type reactions, ring-opening reactions. Its is also used as a promoter in cross-coupling reactions and cyclization of carbocycles and heterocycles.
Application
Reactant for:
Preparation of deprotecting agents in preparation of cellulose derivatives
Synthesis of lipophilic peptides for DNA transfections in vivo
Dehydrobromination reactions
Tetrabutylammonium fluoride trihydrate can be used as a base:
- For the dehydrobromination of vinyl bromides to terminal acetylenes.
- In the conversion of 1,1-dibromo-1-alkenes to terminal alkynes via Corey–Fuchs reaction.
- In Hiyama cross-coupling reaction of aryl and heteroaryl chlorides with aryltrialkoxysilanes in the presence of a palladium catalyst.
It can be used to catalyze ethynylation of quinolines and isoquinolines using calcium carbide in aqueous N,N-dimethylacetamide.
Other Notes
Reagent for the cleavage of silyl ethers and other silyl protecting groups; Catalyst for various reactions with silicon compounds; Use as a base in organic synthesis; Instability of anhydrous TBAF
