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

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 0026; 0029-0031; 0034-0036; 0039-0041; ..., (2021/07/21)
The invention discloses a preparation method of fluoroethylene carbonate. The preparation method comprises the steps of preparation of phenyl iodine difluoride and preparation of fluoroethylene carbonate. The method has the beneficial effects that the synthesis of the fluoroethylene carbonate does not need to use a toxic chlorination reagent, and the cheap raw materials hydrogen peroxide and hydrogen fluoride are used; according to the preparation method, the high-purity fluoroethylene carbonate is obtained by directly distilling in a fluoroethylene carbonate synthesis reaction kettle, and the operation is simple; wherein, the acetic acid, iodobenzene, the organic solvent and the catalyst palladium acetate (II) in the preparation process of fluoroethylene carbonate are recycled, so that the cost is saved.

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.
