• sodium diselenide
• diselenides
• alkaline

This paper described a novel method that is in alkaline protonic solvent (water or ethanol) to prepare sodium diselenide with a 8: 1 molar ratio of selenium to sodium borohydride, then to synthesize organic diselenides. Compared with the reaction in neutral solution described in literature, this method has advantages as below. (1) To prepare same amount of diselenide, the amount of NaBH4 in alkaline solution is only 1/8 of that in neutral solution. (2) The reaction proceeded mildly with no injurious gas forming. (3) The operation is convenient and safe. (4) The obtained Na2Se2 solution can be utilized directly to synthesize diselenides with higher yields.
