PREPARATION OF AROMATIC AMINO COMPOUND BY ONE-STEP REACTION OF AROMATIC COMPOUND WITH AZIDE IN THE PRESENCE OF HALOGENATED ACETIC ACID OR HALOGENATED METHANESULFONIC ACID

摘要

PURPOSE:To prepare an aromatic amino compound, economically, in one step, by reacting an aromatic compound with an azide in the presence of a halogenated acetic acid or a halogenated methanesulfonic acid. CONSTITUTION:An aromatic amino compound such as phenylcarbamic acid ethyl ester, diphenylamine, etc. is prepared by reacting an aromatic compound such as benzene, toluene, etc. with an azide compound such as azidoformic acid ethyl ester, phenylazide, etc. in the presence of a halogenated acetic acid such as trifluoroacetic acid, trichloroacetic acid, etc. or a halogenated methanesulfonic acid such as trifluoromethanesulfonic acid, etc.
