Descrição

Aplicação

• 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.[1]
• In the nucleophilic fluorination of organic halides, tosylates, and triflates.[1]
• For the regioselective synthesis of fluorohydrins by ring-opening of terminal epoxides.[1]
