应用
- Used as an etchant for silica films
Reactant for:
- Nucleophilic fluorination
- Ring-opening fluorination reaction
- Substitution reactions
Tetrabutylammonium hydrogen difluoride (TBABF) can be used as a reagent:
- For the conversion of aromatic boronic acids and esters into corresponding tetrabutylammonium trifluoroborate salts. These salts are utilized as surrogates of boronic acids in Suzuki-Miyaura cross-coupling reactions.
- In the nucleophilic fluorination of organic halides, tosylates, and triflates.
- For the regioselective synthesis of fluorohydrins by ring-opening of terminal epoxides.
