Abstract

An aromatic compound, which may be an aromatic hydrocarbon, a halogenated aromatic hydrocarbon, a carboxylic acid ester of a hydroxyaromatic compound or an ester of an aromatic acid, is chlorinated or brominated in the nucleus by treatment with (a) iron or a metal of the platinum group or a compound of any of these metals, (b) a source of nitrate ions and (c) a source of chloride or bromide ions, or perchloric acid. A number of iron or platinumgroup metal compounds are specified, as also are a number of sources of chloride or bromide ions. The source of nitrate ions may be nitric acid, sodium nitrate, nitric oxide, nitrous anhydride, a nitrite, nitrous acid, nitrogen di- or tetra-oxide or nitric anhydride. A single compound, e.g. palladium nitrate or ferric chloride, may provide both the iron or platinum-group metal compound and the nitrate, chloride or bromide ion. The reaction is preferably effected at about 60-150 C. in a solvent and in the presence of molecular oxygen. Examples are given of the treatment of benzene, chlorobenzene, toluene, phenyl acetate, methyl benzoate and naphthalene. Reference is made also to the treatment of ethylbenzene, cumene, anthracene, biphenyl, phenanthrene, t-butylbenzene, [alpha]-phenylnaphthalene, p-xylene, terphenyl, 3-phenylheptane, 1,4-diphenylbutane, diphenylmethane and tetralin.
