Reaction Conditions:

with selenium;potassium hydroxide in water at 60; for 0.5 h;

Steps:

2 Example 2: Preparation of Dialkyl Diselenide Compound II-2

The reaction formula is as follows:Add 99mg (1.25mmol) of selenium powder and 84mg (1.5mmol) of potassium hydroxide to the reaction flask, then add 0.5mL of water, and then add 156mg of ethyl iodide (1mmol) I-2 into the reaction flask under stirring. The reaction was stopped for 0.5h at 60°C. Filter, wash the filter cake twice with ethyl acetate (1mL×2), combine the filtrates, add 3 mL of water, mix well and stand for separation. After collecting the ethyl acetate layer, the water layer is washed with ethyl acetate (2mL×2). ) Extract twice, combine the ethyl acetate phases, and evaporate the ethyl acetate on a rotary evaporator to obtain 107 mg of dialkyl diselenide compound II-2 with a yield of 99%.
