氢氧化铯存在下, 以无水N,N -二甲基甲酰胺(DMF)作溶剂, 在室温下水合肼还原硒形成的二硒化铯与含官能团的卤代烃或磺酸酯反应, 高收率地形成对应的二烷基二硒醚.

关键词: 氢氧化铯, 二烷基二硒醚, 水合肼,

In the presence of cesium hydroxide, using dry N,N -dimethylformamide (DMF) as solvent, hydrazine hydrate reduced selenium to give cesium diselenide, which reacted with functional alkyl halide or tosylates at room temperature to afford the corresponding diaryl diselenides in high yields.

Key words: cesium hydroxide, diaryl diselenide, hydrazine hydrate, selenium
