CuI/TMEDA-catalyzed cross-coupling reaction of N-(2-haloaryl)trifluoroacetimidoyl chlorides with primaryamines. The present double amination process tolerates the presence of Cl, Br, or I substituent at the 2-position of the phenyl group. copper - double amination - N-(2-haloaryl)trifluoroacet-imidoyl chlorides - primaryamines - benzimidazoles
