1H-1,2,3-triazoles can be prepared in good yield by the reaction of terminalalkyne and sodiumazide in the presence of cuprous chloride at a temperature higher than 70 °C. The alkyne is unactivated and the reaction has to be carried out under inert gas. At room temperature, the reaction first gives a Cu(I)-azide complex which is converted to a Cu-alkyne complex when the temperature is raised to higher
末端炔烃与叠氮化钠在氯化亚铜存在下,在高于 70 ℃的温度下反应,可以高收率地制备 1H-1,2,3-三唑。炔烃是未活化的,反应必须在惰性气体下进行。在室温下,反应首先产生 Cu(I)-叠氮化物配合物,当温度升至高于 70 °C 时,该配合物转化为 Cu-炔烃配合物。Cu(I)-炔烃配合物和叠氮化物离子从Cu(I)解离或配位到Cu(I)的反应然后得到1H-1,2,3-三唑。
