Paragraph 0148-0150; 0152; 0166, (2021/05/29)
A safe, simple, and selective method and reagent for deoxyfluorination is disclosed. With the method and reagent disclosed herein, organic compounds such as carboxylic acids, carboxylates, carboxylic acid anhydrides, aldehydes, and alcohols can be fluorinated by using the most common nucleophilic fluorinating reagents and electron deficient fluoroarenes as mediators under mild conditions, giving corresponding fluoroorganic compounds in excellent yield with a wide range of functional group compatibility and easy product purification. For example, directly utilizing KF for deoxyfluorination of carboxylic acids provides the most economical and the safest pathway to access acyl fluorides, key intermediates for syntheses of peptide, amide, ester, and dry fluoride salts.

In order to overcome the problems of high cost and poor stability of the existing deoxidation fluorination reagent, the invention provides a fluorination reagent. The fluorination reagent comprises acation M and an anion, and the anion is selected from one or more of the following perfluoropolyether chain carboxylic acid anions: CF3 (OCF2) nCO2, and n is selected from 1-10. Meanwhile, the invention further discloses a deoxidation fluorination method. The fluorination reagent provided by the invention has the advantages that the materials are easy to obtain, the fluorination products can beobtained at higher yield for various alcohol substrates, and the universality for different alcohol substrates is better.
