Document Type and Number:
Japanese Patent JP7381912
Kind Code:
B2
Abstract:
Provided is a method for producing a compound represented by general formula (1) [wherein R1 represents a hydrogen atom, a hydroxyl group, a fluorine atom, a cyano group, a nitro group, a hydrocarbon group or a perfluoroalkyl group; X1's may be the same as or different from each other and independently represent a halogen atom other than a fluorine atom; and n represents an integer of 1 to 6 and n1 represents an integer of 1 to 6, wherein n ≥ n1 and n1 represents an integer of 2 to 6 when n represents an integer of 2 to 6], the method comprising a step for reacting a compound represented by general formula (2) [wherein R1, X1 and n are as mentioned above] with a metal fluoride in a solvent comprising a nitrogenated organic compound in the presence of a phosphonium salt having at least one alkyl group to produce the compound represented by general formula (1), in which, when n represents an integer of 2 or more, at least two X1's are fluorinated in the reaction. The production method is a novel method whereby a fluorinated aromatic compound can be produced with high efficiency.
