ABSTRACT:
ar-(Hydrocarbylthio)aromatic amines, such as (alkylthio) anilines, are prepared by heating one or more other ar-(hydrocarbylthio)aromatic amines in the presence of a catalyst, such as aluminum chloride, to redistribute the hydrocarbylthio groups with little or no co-formation of secondary or tertiary amines. The amine starting material is one or more primary aromatic amines having at least one free ring position and at least one hydrocarbylthio substituent in a ring position other than a meta-position.
