A convenient method for one‐pot two‐step 1,3‐dipolar cycloadditon reaction of arylboronic acid, sodium azide followed with terminal alkynes in the presence of 2‐pyrrolecarbaldiminato‐Cu(II) complexes catalyst is reported. Various 1‐aryl‐1,2,3‐triazoles were prepared in 63%–97% yields in water at 30°C without any additives and avoiding the isolation of unstable aryl azides.
