Abstract
Official abstract text for this publication.
The present invention provides a halogenated aniline represented by formula (I) (wherein each of X 1 and X 2 independently represents a chlorine atom, a bromine atom or an iodine atom), a method for producing the halogenated aniline, and other aspects.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a halogenated nitrobenzene, comprising: a step of halogenating 1,2-difluorobenzene or a 1-halogeno-3,4-difluorobenzene to obtain a halogenated benzene represented by formula (III): wherein each of X 1 and X 2 independently represents a chlorine atom, a bromine atom or an iodine atom, and a step of subsequently nitrating the halogenated benzene to obtain a halogenated nitrobenzene represented by formula (II): wherein each of X 1 and X 2 independently represents a chlorine atom, a bromine atom or an iodine atom. 2. The method for producing a halogenated nitrobenzene according to claim 1 , wherein fuming sulfuric acid and concentrated nitric acid are added to the halogenated benzene represented by formula (III) to nitrate the halogenated benzene. 3. The method for producing a halogenated nitrobenzene according to claim 1 , wherein fuming sulfuric acid and fuming nitric acid are added to the halogenated benzene represented by formula (III) to nitrate the halogenated benzene.
