Paragraph 0169-0212, (2021/01/12)
In order to overcome the problems of high cost and low stability of the existing fluorination reagents for preparing acyl fluoride, sulfonyl fluoride and phosphoryl fluoride compounds, the invention provides a fluorination method, which comprises the following operation steps of: adding a fluorination reagent into a substrate, wherein the fluorination reagent comprises cations M and anions, the anions are selected from one or more of perfluoropolyether chain carboxylic acid anions as shown in the specification: CF3(OCF2)nCO2, wherein n is selected from 1-10; the substrate comprises a carboxylic acid compound, a sulfonic acid compound, a phosphoric acid compound and a phosphine oxide compound; and carrying out fluorination reaction to obtain acyl fluoride, sulfonyl fluoride and phosphoryl fluoride products. According to the fluorination method provided by the invention, the perfluoropolyether chain carboxylate is used as a fluorination reagent, so that the dehydroxylation fluorination reaction of the carboxylic acid compound, the sulfonic acid compound and the phosphoric acid compound and the fluorination reaction of the phosphine oxide compound are realized, the product yield isrelatively high, and the fluorination method has relatively good universality for different substrates.
