The electrochemical fluorination of organosulfur compounds in triethylamine/hydrofluoric acid (Et3N-5HF) with polystyrene-supported iodobenzene (PSIB) and tetraethylammonium chloride (Et4NCl) was performed successfully in an undivided cell under constant current conditions to afford the corresponding fluorinated compounds in moderate to good yields. Recycle use of the PSIB could be achieved due to its easy separation. Notably, the mediatory activity of the iodobenzene derivative was not appreciably changed even after 10 recycle uses.
Electroorganic synthesis under solvent-free conditions. Highly regioselective anodic monofluorination of cyclic ethers, lactones, and a cyclic carbonate

, p. 1503 - 1505 (2002)
Regioselective anodic fluorination of cyclic ethers, lactones, and a cyclic carbonate in Et4NF·nHF (n = 4, 5) and Et3N·5HF without a solvent was successfully carried out to give the corresponding monofluorinated products in moderate yields. This is the first report of direct electrochemical fluorination of cyclic ethers, lactones, and a cyclic carbonate using anodic fluorination.

Paragraph 0022-0027, (2021/11/10)
The invention discloses a rapid continuous flow synthesis process of fluoroethylene carbonate, which comprises the following steps. Step I, EC vent nitrogen is added to the reaction kettle to be heated to the reaction temperature, thionyl chloride is added dropwise, and then an amount of AIBN is dropwise added, and the reaction 1.5 - 2h is carried out under 200 - 220Pa under reduced pressure. Step II. When the whole reaction of chloroethylene carbonate is completed, the reaction process is monitored by gas chromatography, and the reaction progress is monitored 1 - 3h through gas chromatography, and then the reaction process is monitored by gas chromatography, and the filtrate is filtered and the filtrate is filtered and the filtrate is 30 °C evaporated off under reduced pressure. The method avoids tedious work of repeated long-time operation in the past process, reduces labor intensity, shortens reaction time, and is suitable for continuous industrial production.

Paragraph 0020-0047, (2020/03/09)
The invention relates to a fluoroethylene carbonate production method. A purpose of the invention is mainly to solve the problems of high catalyst cost and low product yield in the prior art. According to the technical scheme of the invention, the method comprises: adding chloroethylene carbonate into a reactor, adding a polar aprotic solvent, a catalyst and a fluorinating reagent, reacting undera certain reaction condition, and separating reaction liquid by using a separation unit after the reaction is finished so as to obtain the fluoroethylene carbonate product. With the technical scheme of the invention, the problems in the prior art are well solved. The method of the invention can be applied to production of fluoroethylene carbonate.
