ortho-C–H bond halogenation of anilides and N-aryl carbamates using easily available N-halosuccinimides (NXS) as the active halogenation reagent in the presence of nickel or silver catalyst has been developed. This method provides a new approach to 2-haloanilides and carbamates, which may serve as starting materials for the synthesis of pharmaceutically and biologically active compounds.

practical strategy for cericammoniumnitrate promoted highly chemo- and regioselective ortho-nitration of aniline carbamates has been developed under mild and neutral conditions without the requirement of additional catalyst and oxidant. Both electron rich and highly electron-deficient anilines afforded good to excellent yields of the desired products with outstanding functional groups tolerance.
