We demonstrate exceptional levels of regioselectivity in the tandem, animation reactions between 1,2-differentiated dihaloarenes and N-substituted amidines, The regiochemical outcome of this Cul-catalyzed reaction is achieved through a combination of N1/N2 chemoselectivity on the amidine and reactivity-controlled X1/X2 chemoselectivity on the 1,2-dihaloarene. This reaction proves to be fairly general for the regiospecific synthesis of 1,2-substituted benzimidazoles.
