The alkyne was unactivated and the reaction was carried out under inert gas. At room temperature, the reaction first gave a Cu(I)-azide complex which was converted to a Cu-alkyne complex when the temperature was raised to higher than 70 °C. The reaction of Cu(I)-alkyne complex and azide ion dissociated from or coordinated to Cu(I) then gave 1H-1,2,3-triazoles.
