Abstract
A method of preparing a difluorinated alcohol compound is provided. The difluorinated alcohol compound can be easily synthesized when an aldehyde and N-fluorobenzenesulfonimide are reacted in the presence of L-proline, and thus the method has advantage in that preparation processes are simple and reagents are economical and safe, compared to the related-art methods. Therefore, the preparation method can be effectively applied to prepare a difluorinated alcohol used in various applications for raw materials such as functional medicines, agricultural chemicals, polymerizable compounds, etc.
