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.
Cesium diselenide formed by the hydrazine reduction of selenium with anhydrous N, N’-dimethylformamide (DMF) as a solvent in the presence of cesium hydroxide is reacted with a functional group-containing halogenated hydrocarbon or sulfonate , The corresponding dialkyl diselenide is formed in high yield.
