General description
Potassium fluoride (KF) on activated alumina is a highly reactive catalyst (basic in nature) for various organic reactions. High reactivity is due to the formation of potassium hexafluoroaluminiate, potassium hydroxide and potassium aluminate on the interaction of its fluoride ion with alumina. Celite coated with potassium fluoride participates in various hydrogen-bond-mediated reactions. Potassium fluoride on basic alumina in acetonitrile has been employed for the ultrasound-assisted deprotection of tert-butyldimethylsilyl ethers of phenols. Neutralization reaction of hydrofluoric acid with KOH or postassium carbonate affords KF.
Application
Potassium fluoride may be employed for doping the natural calcium phosphate (NP) for high yield synthesis of activated alkenes.
A versatile fluoride ion source used in a study of ion-specific swelling and de-swelling of ampholytic polymer gels, in the room temperature oxidation of noble metals in HF, and in the measurement of electronic polarizabilities of ions in polymers of alkali halides.
