A mixed Cu I /Cu II catalyst based on magnetic cysteine functionalized graphene oxide (Cu I/II @Cys‐MGO) was prepared and used for the azidonation reaction of aryl boronic acids and one‐pot synthesis of 1,4‐diaryl −1,2,3‐triazoles. Aryl azides were obtained in good yields and short reaction times via cross‐coupling of aryl boronic acids with sodium azide in the presence of Cu II catalytic species in this catalytic system. The azide‐alkyne cycloaddition reaction was catalyzed by CuI catalytic species in Cu I / II @Cys‐MGO nanocomposite.
