碳酸铯催化下端炔碘化合成炔基碘
Cesium Carbonate Catalyzed Iodination of Terminal Alkynes to Synthesize 1-Iodoalkynes
【摘要】 催化量的碳酸铯(0.2equiv.)、氢氧化钾(2.0equiv.)及端炔(1.0equiv.)在无水THF-HMPA中,室温搅拌3h,然后加入碘的THF溶液,室温搅拌2h,生成炔基碘.产率为70%~93%.
【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.
