Applicazioni

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.

Note

Light sensitive. Hygroscopic. Incompatible with strong acids and oxidizing agents.
