Cu-catalyzed cross coupling between phosphinic amides and aryl halides was accomplished for the first time by using(±)-trans- cyclohexane-1,2-diamine as the ligand.This reaction provided a novel approach for synthesizing arylated phosphinic amides.Both kinetic measurement and theoretical calculation indicated that phosphinic amides were much less reactive than amides by about 10 times in Cu-catalyzed cross coupling.
