Direct fluorination of cyclic 1,3-diones gives 2-mono- and 2,2-di-fluorinated products. The monofluorinated compounds crystallise in their enol forms and the difluorinated compounds form stable monohydrates whose crystal structures have been elucidated. Direct fluorination of phlorogulcinol in formic acid yields 1,1,3,3,5,5-hexafluoro-2,2,4,4,6,6-hexahydroxycyclohexane.
环状1,3-二酮的直接氟化反应生成2-一氟和2,2-二氟的产物。单氟化化合物以其烯醇形式结晶,而二氟化化合物形成稳定的一水合物,其晶体结构已经阐明。邻苯三酚在甲酸中直接氟化产生1,1,3,3,5,5-六氟-2,2,4,4,6,6-六羟基环己烷。
