摘要

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