Reaction Conditions:

in ethyl acetate for 18 h;Reflux;

Steps:

1.235 g of dithioperthiobenzoic anhydride (4 mmol) and 1.002 g of AIBN (6 mmol) were placed in a 100 mL three-necked flask, and the apparatus was refluxed on a condenser, the system was closed, and the gas was exchanged three times for 10 min each time. .Then 30 mL of anhydrous, anhydrous ethyl acetate was added and the reaction was refluxed for 18 h.After the reaction was stopped, it was directly dried and then separated through a column, and the developing solvent was a mixed solvent of petroleum ether and ethyl acetate (volume ratio) of 50:1.The product was collected points, spin dry, drained vacuo to give a dark red solid 1.504g (CPBD), yield 85%.
