Title:
フッ素化芳香族環化合物の製造方法
Document Type and Number:
Japanese Patent JP2004503515
Kind Code:
A
Abstract:
A process is provided for increasing the fluorine content of benzene or pyridine rings which are optionally substituted with from 1 to 3 inert substituents. The process involves (a) contacting the ring with a metal fluoride composition comprising cupric fluoride (CuF2) at a temperature above 250 DEG C sufficient to transfer F from cupric fluoride to the optionally substituted ring, thereby chemically reducing the metal fluoride compositions; (b) oxidizing the reduced metal fluoride composition from (a) in the presence of HF to regenerate a metal fluoride compposition comprising cupric fluoride; and (c) employing regenerated metal fluoride composition of (b) in (a).
