実験手順
The specific preparation is described as follows: refluxing 3-bromo-1,2-diaminobenzene in ethanol solution, then adding into selenium dioxide dissolved in hot water, after that, refluxing for 2 hours. The precipitation is recrystallized with ethyl acetate after being filtered to get 4-bromo-2,1,3-benzoselenadiazole finally.
