Silver fluoride Chemical Properties,Usage,Production
Chemical Properties
orange to brown solid
Uses
Silver(I) fluoride is used as a fluorination and desilylation reagent in organic synthesis. In medical filed, it is used as topical caries in aqueous form in dentistry. It is employed in organofluorine chemistry for addition of fluoride across multiple bonds, especially to prepare perfluoroalkylsilver(I) by reacting with alkenes. Further, it is involved in the preparation of tetralkylammonium fluorides by the reaction with tetralkylammonium bromide. In addition to this, it is used as a desulfuration-fluorination reagent on thiourea derived substrates.
Uses
- Silver fluoride is applied to convert organic Br and Cl Compounds to their fluoro analogs; as antiseptic.
- Preparation of bromoacetylenes from bulky, trialkylsilylacetylenes.
- Also used in a palladium-catalyzed cross coupling of acetanilides with trialkoxysilanes.

Definition
ChEBI: Silver monofluoride is a silver salt and a fluoride salt.
Preparation
Silver(I) fluoride was prepared by reacting hydrogen fluoride with the carbonate and with the oxide.
General Description
Odorless yellow to gray solid. Sinks and mixes with water.
Air & Water Reactions
Water soluble.
Reactivity Profile
Boron reacts explosively when ground with Silver fluoride; silicon reacts violently [Bretherick 1979 p, 197]. Dimethyl sulfoxide is violently reactive with fluorinating agents such as Silver fluoride [Chem. Eng. News 44(24):7 1956]. When Silver fluoride is ground with calcium hydride the mass becomes incandescent [Mellor 3:389 1946-1947]. CaH2 reacts incandescently with AgF if subject to friction. (Mellor, 1941, Vol. 3, 389, 651).
Hazard
Strong irritant.
Health Hazard
Inhalation of dust causes irritation of nose and throat. Ingestion may cause vomiting, salty taste, abdominal pain, diarrhea, convulsions, collapse, thirst, disturbed color vision, and acute toxic nephritis. Contact with eyes causes irritation. Skin may be blackened on prolonged exposure.
Purification Methods
The fluoride is a hygroscopic solid with a solubility of 135g/100mL of H2O at 15o, and forms an insoluble basic fluoride in moist air. Purify it by washing with AcOH and dry *C6H6, then keep it in a vacuum desiccator at room temperature to remove *C6H6, and store it in opaque glass bottles. The flaky hygroscopic crystals darken on exposure to light. It attacks bone and teeth. [Sharpe J Chem Soc 4538 1952, Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 240 1963.]
