Application
Reactant for:
- Reaction with K tert-butoxide to give disilylated fluorosilylenoid for subsequent self-condensation to fluorodisilanyl anion
- Cross-coupling reactions with vinyl and aryl triflates
- Cocatalyst in phase-transfer fluorination of alkyl halides and sulfonates
- Used as a nucleophilic fluorinating agent
Other Notes
Hypervalent tin fluoride: a useful nonhygroscopic, very stable (to up to 210°) fluorinating agent
