Description

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
