氢氧化铯催化下,以商业THF作溶剂,端炔与二芳基二硒醚在氮气保护下,25或35 ℃时反应,立体选择地生成(Z)-1,2-二芳硒基烯.

关键词: 立体选择合成, 二芳基二硒醚, 氢氧化铯, (Z)-1,2-二芳硒基烯

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
