Cesium hydroxide effectively catalyzed the addition of diaryldiselenides to terminal acetylenes in commercial THF under N2 at 25 or 35 ℃to give exclusively (Z)-1,2-bis(arylseleno)-1-alkenes in high yields.

Key words: stereoselective synthesis, diaryl diselenide, cesiumhydroxide, (Z)-1,2-bis(arylseleno)-1-alkene
