Antimony trifluoride is the inorganic compound with the formula SbF 3. Sometimes called Swarts' reagent, it is one of two principal fluorides of antimony, the other being SbF 5. It appears as a white solid. As well as some industrial applications, [2] it is used as a reagent in inorganic and organofluorine chemistry.
Swarts fluorination is a process whereby the chlorine atoms in a compound – generally an organic compound, but experiments have been performed using silanes – are replaced with fluorine, by treatment with antimony trifluoride in the presence of chlorine or of antimony pentachloride. Some metal fluorides are particularly more useful than ...
Carboxylic acids can be converted to trifluoromethyl groups by treatment with sulfur tetrafluoride and trihalomethyl compounds, particularly trifluoromethyl ethers and trifluoromethyl aromatics, are converted into trifluoromethyl compounds by treatment with antimony trifluoride/antimony pentachloride (the Swarts reaction).
Antimony fluoride may refer to either of the following: Antimony trifluoride, SbF 3; Antimony pentafluoride, SbF 5 This page was last edited on 12 March 2021 ...
Actinium trifluoride, AcF 3; Aluminium trifluoride, AlF 3; Americium trifluoride, AmF 3; Antimony trifluoride, SbF 3, sometimes called Swart's reagent; Arsenic trifluoride, AsF 3 ...
Frédéric Swarts also introduced antimony fluoride in this role in 1898. [39] [42] The nonflammability and nontoxicity of the chlorofluorocarbons CCl 3 F and CCl 2 F 2 attracted industrial attention in the 1920s. General Motors settled on these CFCs as refrigerants and had DuPont produce them via Swarts' method. [39]
Bis(trifluoromethyl)peroxide (BTP) is a fluorocarbon derivative first produced by Frédéric Swarts. [3] It has some utility as a radical initiator for polymerisation reactions. BTP is unusual in the fact that, unlike many peroxides, it is a gas, is non-explosive, and has good thermal stability.
Ethyl trifluoroacetate can be obtained by reacting 2,4,6-tris-(trifluoromethyl)-1,3,5-triazine with ethanol in the presence of hydrochloric acid. The former, in turn, can be prepared by a two-step reaction starting from trichloroacetonitrile by reaction with hydrogen chloride and fluorination of the intermediate with antimony trifluoride.
