Anwendungen & Verwendung
Verwenden
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. 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.
Herstellung & Synthese
synthetische
Silver(I) fluoride was prepared by reacting hydrogen fluoride with the carbonate and with the oxide.
