(57) [Summary] [Structure] Formula (I) F n ArNH 2 (I) [wherein n is 1, 2, 3 or 4, Ar is phenyl, naphthyl or pyridyl, and an Ar residue The remaining substituents above are the same or different and independently of each other hydrogen, halogen, (C 1 -C 4 ) -alkyl, phenyl, NR 2 , OR, CN, CHO or COR (wherein R is hydrogen or (C 1 -C 6 ) -alkyl)] and is represented by the formula (II) X m F n ArNO 2 (II) [wherein n, Ar and the remaining substituents on the Ar residue have the meanings given above, X is chlorine or bromine, and m is 1, 2, 3 or 4] is reacted with hydrogen in the presence of a palladium catalyst, a water-insoluble non-water-soluble amine which does not form a hydrogen halide, and optionally an inert solvent. The above method characterized by the above. [Effect] High-purity fluoroaniline can be produced in a high yield and easily obtained from a precursor that can be used on an industrial scale by an industrially suitable method. |
