By altering the amount of Selectfluor, a highly selective mono- and difluorination of 1,3-dicarbonyl compounds provides various 2-fluoro- and 2,2-difluoro-1,3-dicarbonyl compounds in very good yields. This practical and convenient fluorination can be performed in aqueous media without any catalyst and base.
