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.[1]
- To generate tetrabutylammonium fluoride in situ by reacting with tetrabutylammonium hydrogensulfate, which can catalyze the esterification of carboxylic acids with alkyl halides[2] and ring-opening of aziridines.[3]
- In combination with chlorotrimethylsilane for the desilylation of O-tert-butyldimethylsilyl ethers.[4]
