Application

Potassium fluoride dihydrate may be used in the following processes:
  • As a source of active fluoride ion when used in combination with tetra-n-butylammonium chloride.
  • To generate tetrabutylammonium fluoride in situ by reacting with tetrabutylammonium hydrogensulfate, which can catalyze the esterification of carboxylic acids with alkyl halides and ring-opening of aziridines.
  • In combination with chlorotrimethylsilane for the desilylation of O-tert-butyldimethylsilyl ethers.
