Electrochemical fluorination of a benzylic position in sulfolane solvent was written by Laurent, Eliane;Marquet, Bernard;Tardivel, Robert. And the article was included in Journal of Fluorine Chemistry in 1990.Safety of Ethyl 2-fluorophenylacetate This article mentions the following:
The use of sulfolane as a solvent instead of MeCN in the electrofluorination of benzylic derivatives, e.g. RC6H4CH2E [R = H, Cl; E = COMe, CO(OEt), CN)], gives greater yields of benzylic fluorides (e.g. RC6H4CFHE) because the formation of acetamido byproducts is prevented. However, the parallel fluorination of the aromatic nucleus is not avoided under these conditions. In the experiment, the researchers used many compounds, for example, Ethyl 2-fluorophenylacetate (cas: 584-74-7Safety of Ethyl 2-fluorophenylacetate).
Ethyl 2-fluorophenylacetate (cas: 584-74-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of Ethyl 2-fluorophenylacetate
