实验过程

The mixture of 2.0 g (0.0127 mol) of dichloroglyoxime (Compound No.6), 20 ml of dichloroethane and 2.4 g (0.0306 mol) of acetyl chloride was stirred in an ice bath. To the mixture, triethylamine (3.1 g, 0.0307 mol) was added dropwise, followed by stirring for 30 minutes. The reaction mixture was washed twice with 15 ml of water. The dichloroethane solution was concentrated under reduced pressure, to obtain white crystals of dichloroglyoxime diacetate (Compound No.2, yield: 30%).
