| Abstract: | A mixture of cesium carbonate (0.2 equiv.), potassium hydroxide (2.0 equiv.) and terminal al-kynes (1.0 equiv.) in THF-HMPA was stirred at room temperature for 3 h, then the solution of iodine in THF was added and stirred at room temperature for 2 h. The 1-iodoalkynes were obtained in 70%～93% yields. |
