Copper catalyzed synthesis of 1-aryl-1,2,3-triazoles from aryl iodides, alkynes, and sodium azide

Aryl azides were synthesized using heterogeneous porous Cu (0) catalyst via a coupling reaction of aryl iodides with sodium azide under mild conditions. Under the same conditions, one-pot Cu-catalyzed azide–alkyne cycloaddition of aryl iodides, alkynes, and sodium azide yielded 1-aryl-1,2,3-triazoles.
