Abstract: | A mixed CuI/CuIIcatalyst based on magnetic cysteine functionalized graphene oxide (CuI/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 CuII catalytic species in this catalytic system. The azide-alkyne cycloaddition reaction was catalyzed by CuI catalytic species in CuI/II@Cys-MGO nanocomposite. |
