Description

Application

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.
