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 ...
The Swarts reaction is generally applied to the synthesis of organofluorine compounds, but experiments have been performed using silanes. [8] It was once used for the industrial production of freon. Other fluorine-containing Lewis acids serve as fluorinating agents in conjunction with hydrogen fluoride.
This reaction also affords (C 5 H 5) 2 ZrH 2, which is treated with methylene chloride to give Schwartz's reagent [3] An alternative procedure that generated Schwartz's reagent from dihydride has also been reported. [4] Moreover, it's possible to perform an in situ preparation of (C 5 H 5) 2 ZrHCl from zirconocene dichloride by using LiH.

Unit cell of Hg 2 F 2, with F from adjacent molecules coordinating the Hg atoms. In common with other Hg(I) (mercurous) compounds which contain linear X-Hg-Hg-X units, Hg 2 F 2 contains linear FHg 2 F units with an Hg-Hg bond length of 251 pm (Hg-Hg in the metal is 300 pm) and an Hg-F bond length of 214 pm. [5] The overall coordination of each Hg atom is a distorted octahedron; in addition to ...

Frédéric Jean Edmond Swarts (2 September 1866 – 6 September 1940) was a Belgian chemist who prepared the first chlorofluorocarbon, CF 2 Cl 2 (Freon-12) [1] as well as several other related compounds. He was a professor in the civil engineering at the University of Ghent.
It participates in various co-polymerisation reactions. [2] BTFE telomers are oily liquids sold under the tradename BFC oil. The telomers can be prepared with fluorotrichloromethane or tetrachloromethane as telogens. If tetrachloromethane is used for the telomerisation, it will have -CCl 3 terminals. [5]
