Abstract

An efficient one-pot synthesis of 1-aryl 1,2,3-triazoles from aryl bromides/iodides and terminal alkynes in the presence of sodium azide is described. In the case of aryl iodides, the reactions proceeded at room temperature. The reactions normally gave high yields.

Key words

1,2,3-triazoles - one-pot - copper - 1,3-dipolar cycloaddition - catalyst
