On April 30, 2008, Lu, Li-Hui; Wu, Jia-Hao; Yang, Chia-Hsi published an article.Electric Literature of 5301-96-2 The title of the article was Preparation of 1H-1,2,3-triazoles by cuprous ion mediated cycloaddition of terminal alkyne and sodium azide. And the article contained the following:
1H-1,2,3-triazoles were prepared in good yield by the reaction of terminal alkyne and sodium azide in the presence of cuprous chloride at a temperature higher than 70 °C. 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. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Electric Literature of 5301-96-2
