참여 물질

반응 단계

12 grams (0.09 mol) of aluminum chloride are introduced into a ground-necked flask. 3.1 cm3 (0.04 mol) of dimethylformamide are added dropwise with stirring. After cooling, two grams (0.01 mol) of benzoselenazolinone are added and the mixture is homogenized. It is heated to 70°-80° C. on an oil bath with stirring, and 0.01 to 0.012 mol of acetyl chloride is then added. heating is maintained at a temperature of 80°-90° C. for a time T of approximately 4 h 30 min.
