General description

Tetrabutylammonium fluoride hydrate is known to be a source of F− anion, used in nucleophilic fluorination reactions.

Application

Reactant for preparation of:
  • Double clathrate hydrates at high pressures
  • Cellulose ethers
  • Terminal olefins via dehydrohalogenation reactions
  • Neutral and zwitterionic 3-carboranyl thymidine analogues for boron neutron capture therapy
Tetrabutylammonium fluoride hydrate can be used:
  • To prepare 2,7-diethynyl-9-propyl-9H-carbazole, which is a key intermediate for the synthesis of calix[4]arene−carbazole polymers.
  • As an anion source in the study of selective detection of F− by anion receptor viz Schiff base.
  • To prepare terminal olefins from primary alkyl iodides
