以N,N-二甲基甲酰胺(DMF)作溶剂, 在4 Å分子筛存在及氮气保护下, 将端炔、CsOH、硒粉在室温搅拌2 h, 然后加入二芳基碘盐, 在0 ℃搅拌30 h, 得炔硒醚, 收率约60%.

关键词: 氢氧化铯, 炔硒醚, 二芳基碘盐, 硒

In the presence of 4Å MS, using N,N-dimethylformamide (DMF) as solvent, a mixture of terminal acetylene, cesium hydroxide and element selenium was stirred under N2 atomsphere at room temperature for 2 h, then diaryliodonium salts were added and the resulting mixture was stirred at 0 ℃ for 30 h to give acetylenic selenides in about 60% yields .

Key words: acetylenic selenide, cesium hydroxide, diaryliodonium salt, selenium
