The invention discloses a method for synthesizing selenourea derivatives, which comprises the following steps in molar part: under the protection of nitrogen or argon, firstly, 1-5 parts of first amine, 5-12 parts of chloroform, 2-8 parts of The alkaline substance and the reaction solvent are mixed, and the reaction is stirred at 25°C to 80°C for 1 to 6 hours; then 1 to 6 parts of selenium powder, 1 to 4 parts of alkaline substance, 1 part of morpholine or 1 part of second amine are added, and then The reaction solution is obtained by stirring and reacting at 25° C. to 80° C. for 3 to 8 hours. Then, the selenourea derivative can be obtained by post-processing the reaction solution. It is 5～10mL/g. The method for synthesizing selenourea derivatives disclosed in the invention has the following beneficial effects: (1) the raw materials are simple and easy to obtain, and the reaction conditions are mild; (2) the product yield is relatively ideal; (3) the asymmetric selenourea derivatives are realized Synthesis. |
