Embodiment Construction
[0022] The present invention will be further described below through specific examples, but not as a limitation.
[0023] A, B, C, D, and E in the examples are used as numbers.
[0024] Implementation 1: Preparation of 4-methylhomopiperazine bismuth dicarbamate (A)
[0025] Add 0.571 g (5 mmol) of 1-methylhomopiperazine, 0.25 g (6 mmol) of sodium hydroxide, and 10-15 mL of anhydrous methanol into a 50 mL round bottom flask, and stir magnetically in a cold water bath at 0-5 °C After dissolving, add dropwise 0.76g (10 mmol) CS 2 , low temperature magnetic stirring reaction for 1 h, 10-50 ° C magnetic stirring reaction for 3 h.
[0026] 0.53 g (1.7 mmol) BiCl 3 Dissolve it in 5-15 mL of anhydrous methanol, drop it into the above reaction solution, add a certain amount of dichloromethane, and stir at room temperature for 3 h. After the reaction, a certain amount of water was added, the dichloromethane layer was separated, washed with water, dried over anhydrous sodium sulfate,...
