The copper(Ⅰ) catalyzed coupling reaction of substituted propargyl tosylate with propargyl alcohol proceeds smoothly at room temperature to give 2,5-diynyl alcohol under solid-liquid phase transfer condition. A number of 2,5-diynyl alcohols and 2,5,8-triynyl alcohols were synthesized in this way in good yield.
