Sodium chlorate/hydrochloric acid mixtures were used to chlorinate activated arenes and the $\alpha$-position of ketones. This chlorination method was used to produce selectively mono-, di-, and trichlorinated compounds by controlling the molarity of sodium chlorate. This reagent proved to be much more efficient and easier to handle than chlorine gas.
The reactions of acetanilides with a calculated amount of benzyltrimethylammonium tetrachloroiodate in acetic acid at room temperature or at 70°C gave, selectively, the desired chloro-substituted acetanilides in good yields.
