1,3-Dicarbonyls, such as 1,3-diketones and 1,3-ketoesters, react directly with elemental fluorine at room temperature to give the corresponding 2-fluoro- and, in some cases, 2,2-difluoro-compounds in high yield.

Room-temperature fluorination of pentane-2,4-dione with CsSO4F gave 3-fluoro and 1,3-difluoro derivatives, while 5,5-difluorobarbituric acid was formed in high yield in a 2 h reaction at 100 °C; 1,3-dimethyluracil was converted in methanol via cis- and trans-5-fluoro-6-methoxy derivatives into 5-fluoro-1,3-dimethyluracil in high yield and uridine into 5-fluorouridine.
