4-Halo-1-aminoanthraquinones are formed when anthraisoxazol-6-ones are refluxed in hydrohalic acids.The 3 position undergoes halogenation when 5-substituted isoxazoles are used.The process takes place via a one-proton mechanism with the participation of halide ion in the rate-determining step, possibly with the intermediate formation of N-haloaminoanthraquinones.
